The sei whale is a baleen whale, the third-largest rorqual after the blue whale and the fin whale. Endangered Species Act. Balaenoptera borealis, the formal name of the sei whale, is most often deep gray in color with a lighter gray area covering a portion of its underside and bottom jaw. Direct comparisons of sounds in water to sounds in air can be complicated, see, Prieto, Rui, Monica A. Silva, Martine Berube, Per J. Palsbøll (2012). [76] Seven whales tagged off Faial and Pico from May to June in 2008 and 2009 made their way to the Labrador Sea, while an eighth individual tagged in September 2009 headed southeast – its signal was lost between Madeira and the Canary Islands. Sei whales are pretty adaptable. Sei whales live in all oceans, although rarely in polar or tropical waters. This rorqual is a filter feeder, using its baleen plates to obtain its food by opening its mouth, engulfing or skimming large amounts of the water containing the food, then straining the water out through the baleen, trapping any food items inside its mouth. Gray, J. E. 1846. [10][13] A 1991 study in the North Atlantic estimated only 4,000. In Japanese, the whale was called iwashi kujira, or sardine whale, a name originally applied to Bryde's whales by early Japanese whalers. In the North Atlantic, it feeds primarily on calanoid copepods, specifically Calanus finmarchicus, with a secondary preference for euphausiids, in particular Meganyctiphanes norvegica and Thysanoessa inermis. [39] In the Pacific, the whale has been called the Japan finner; "finner" was a common term used to refer to rorquals. [74], In the North Pacific, the total reported catch by commercial whalers was 72,215 between 1910 and 1975;[11] the majority were taken after 1947.

Small populations reside mainly in the Antarctic Ocean and in some parts of the Indian Ocean. [83] Japanese interests claim this figure is outdated, and in 2002 claimed the western North Pacific population was over 28,000,[88] a figure not accepted by the scientific community. Each plate is made of fingernail-like keratin, which is bordered by a fringe of very fine, short, curly, wool-like white bristles. When feeding they open their mouth and swallow a large gulp of water and prey. Very little is known about their social structure. Scroll below to learn where these magnificent ocean titans reside. [99] The drastic reduction in northeastern Atlantic copepod stocks during the late 1960s may be another culprit. Once stocks of more profitable right whales, blue whales, fin whales, and humpback whales became depleted, sei whales were hunted in earnest, particularly from 1950 to 1980. [10] The specific name is the Latin word borealis, meaning northern. The enormous size with their contrasting … Where do sei whales live? See more. These whales occur in the open ocean and generally avoid coastal waters. Large females lead the northward migration and reach the Denmark Strait earlier and more reliably than other sexes and classes, arriving in mid-July and remaining through mid-September. Perrin, William F., James G. Mead, and Robert L. Brownell, Jr. "Review of the evidence used in the description of currently recognized cetacean subspecies". To receive emails about our campaigns and how you can support them, please enter your email address below and press the ‘subscribe’ button. Balaenoptera borealis ( (northern hemisphere) and B. borealis schlegellii ( southern hemisphere), sei whale tends to follow shelf contours and plankton gatherings of aquatic/marine biomes, in temperate and subpolar regions in the summer, but migrate to sub-tropical waters during the winter. Researchers think this may be a response to the predation rate. Quotas on sei whales in the North Atlantic began in 1977. You can unsubscribe at any time. At the end of the day that's what counted at the time. The sei whale can be found swimming in all of the worlds major oceans, however certain populations may be more abundant than others. As of February 2017[update], the U.S. National Marine Fisheries Service estimated that the eastern North Pacific population stood at 374 whales. [6] More than 2,000 were caught in British Columbian waters between 1962 and 1967. (2006). Like other great whales, they prefer to spend the summer feeding in cooler waters before migrating to … The different estimates result from scientists' inability to observe an entire pregnancy; most reproductive data for baleen whales were obtained from animals caught by commercial whalers, which offer only single snapshots of fetal growth. [65] In Sea of Japan and Sea of Okhotsk, whales are not common, although whales were more commonly seen than today in southern part of Sea of Japan from Korean Peninsula to the southern Primorsky Krai in the past, and there had been a sighting in Golden Horn Bay,[66] and whales were much more abundant in the triangle area around Kunashir Island in whaling days, making the area well known as sei – ground,[67] and there had been a sighting of a cow calf pair off the Sea of Japan coast of mid-Honshu during cetacean survey. [15][16] It has also been referred to as the lesser fin whale because it somewhat resembles the fin whale. Sei whales live in all oceans and seas, except tropical and polar regions. In the late 1970s, some "pirate" whaling took place in the eastern North Atlantic. It inhabits most oceans and adjoining seas, and prefers deep offshore waters. Sei whale usually resides in temperate waters, away from the shore. [29][30][31] The largest specimens taken off Iceland were a 16.15 m (53.0 ft) female and a 14.6 m (48 ft) male, while the longest off Nova Scotia were two 15.8 m (52 ft) females and a 15.2 m (50 ft) male. Sei Whales are found from subtropical to subpolar regions but in deep water and offshore. [54] An observer situated one metre from a vocalizing whale would perceive a volume roughly equivalent to the volume of a jackhammer operating two metres away. [97][98] Sei whales were said to have been scarce in the 1960s and early 1970s off northern Norway. Run, bake, walk, cycle… what could you do for whales and dolphins? Minke Whale – There are two known species of minke whales currently in existence, the common or north Atlantic minke whale (which inhibits the north Atlantic waters) and the Antarctic or southern minke whale (which lives in the Antarctic region south of the equator). Do Sei whale have teeth? I didn't think it was really nice to do that. [25] Their ranges do not overlap. [9] The whale's name comes from the Norwegian word for pollock, a fish that appears off the coast of Norway at the same time of the year as the sei whale. Where do sei whales live? How long does a Sei whale live? The research is conducted by the Institute of Cetacean Research (ICR) in Tokyo, a privately funded, nonprofit institution. [97], Mass death events for sei whales have been recorded for many years and evidence suggests endemic poisoning (red tide) causes may have caused mass deaths in prehistoric times. [9] In the Northern Hemisphere, males are usually 12.8–12.9 m (42–42 ft) and females 13.3–13.5 m (44–44 ft) at sexual maturity, while in the Southern Hemisphere, males average 13.6 m (45 ft) and females 14 m (46 ft). and Christian T. Chimimba. The species remained listed on the IUCN Red List of Threatened Species in 2000, categorized as "endangered". [6], In the North Atlantic between 1885 and 1984, 14,295 sei whales were taken. [83] By the end of whaling, the population was down to between 7,260 and 12,620. They also avoid bodies of water that are semi-enclosed. [31], Despite knowing some general migration patterns, exact routes are incompletely known[31] and scientists cannot readily predict exactly where groups will appear from one year to the next. Since the late 1960s to early 1970s, the sei whale has been second only to the fin whale as the preferred target of Icelandic whalers, with meat in greater demand than whale oil, the prior target. During the colder winter months these whales will travel towar… Growing up to 19.5 metres long, female sei whales are the larger of the two sexes, eclipsing their male counterparts by over 2 metres. They are found in nearly all of the world’s waters from the sub-Arctic and sub-Antarctic, apart from the Mediterranean and Baltic seas. You will find the Sei Whale living in most of the oceans as well as the seas that are adjoined to them. They are found in nearly all of the world’s waters from the sub-Arctic and sub-Antarctic, apart from the Mediterranean and Baltic seas. They are found like many whales in both Northern and Southern hemispheres following the best feeding at different times of year. It appeared to "hitch a ride" on prevailing currents, with erratic movements indicative of feeding behavior in five areas, in particular the CGFZ, an area of known high sei whale abundance as well as high copepod concentrations. [11] Whaling in southern oceans originally targeted humpback whales. Between dives, the whale surfaces for a few minutes, remaining visible in clear, calm waters, with blows occurring at intervals of about 60 seconds (range: 45–90 sec.). Registered Charity (Scotland) No. A newborn is weaned from its mother at 6–9 months of age, when it is 8–9 m (26–30 ft) long,[28] so weaning takes place at the summer or autumn feeding grounds. The sei whale is among the fastest cetaceans. The whale's body is typically a dark steel grey with irregular light grey to white markings on the ventral surface, or towards the front of the lower body. Reaching speeds up to 34.5 miles per hour makes the Sei Whale the fast whale in the water. OUR DATA: We use the most recent data from these primary sources: AnAge, UMICH, Max Planck, PanTHERIA, Arkive, UKC, AKC. During the summer, they are commonly found in the Gulf of Maine, and on Georges Bank and Stellwagen Bank off the U.S. coast in the western North Atlantic. [82] Shore stations in Japan and Korea processed 300–600 each year between 1911 and 1955. The whale's diet preferences has been determined from stomach analyses, direct observation of feeding behavior,[42][43] and analyzing fecal matter collected near them, which appears as a dilute brown cloud. Sei whales appeared off the coast of Norway at the same time as the pollock, both coming to feed on the abundant plankton. [91]. Sei whales, an endangered species, can grow to 65 feet and live as long as 70 years. The bodies of sei whales range in colouring from murky blues to steely greys to deep browns. Researchers attempt to extrapolate conception dates by comparing fetus size and characteristics with newborns. You also have the option to opt-out of these cookies. Other names: Rudolphi's rorqual; Japan finner' Sardine whale; Coalfish whale. [8] The difficulty of distinguishing them at sea from their close relatives, Bryde's whales and in some cases from fin whales, creates confusion about their range and population, especially in warmer waters where Bryde's whales are most common. [72] In the northeast Atlantic, the sei whale winters as far south as West Africa such as off Bay of Arguin, off coastal Western Sahara and follows the continental slope northward in spring. [26] ([27] In the Northern Hemisphere, males reach up to 17.1 m (56 ft) and females up to 18.6 m (61 ft),[28] while in the Southern Hemisphere males reach 18.6 m (61 ft) and females 19.5 m (64 ft)—the authenticity of an alleged 22 m (72 ft) female caught 50 miles northwest of St. Kilda in July 1911 is doubted. Most common in the southern hemisphere, they prefer deep waters and will only approach shores around islands. They eat krill, squid, and small schooling fish by lunge diving or by skimming the water. These calls averaged 82.3 Hz down to 34 Hz over about 1.4 seconds in duration. One whale would always leave the group during or immediately after such socializing bouts. The Sei Whales (pronounced “say”) you might see on your Antarctica cruise are another example of a speedy whale. Adult Sei whales can weigh between 20 and 30 tonnes and grow up to 19.5m in length. The Sei whales body is typically a dark steel grey with irregular light grey to white markings on the ventral surface, or towards the front of the lower body. They prefer temperate waters in the mid-latitudes, and can be found in the Atlantic, Indian, and Pacific Oceans. Sometimes breaching, their bodies leave the water at a low angle and finish with a graceful belly flop. The 33ft mammal, thought to be a Sei whale, was discovered in salt marshes on the north bank of the River Humber near the village of Skeffling. A world where every whale and dolphin is safe and free. Prior to commercial whaling, the North Pacific hosted an estimated 42,000. [13][14], Sei is the Norwegian word for pollock, also referred to as coalfish, a close relative of codfish. Sei whales live in all oceans, although rarely in polar or tropical waters. [27] The average age of sexual maturity of both sexes is 8–10 years. They occupy sub-polar and temperate regions during the summer, migrating to sub-tropical waters in the winter. Along their heads, a single ridge runs from the tip of the nose to  two blowholes and set  aloft  their backs is a sickle-shaped dorsal fin. Sei whales don’t gulp-feed like the other whales in their family. The sei whale is a baleen whale and it lives in most oceans and seas but prefers deep off shore waters. [49] In the Southern Hemisphere, prey species include the copepods Neocalanus tonsus, Calanus simillimus, and Drepanopus pectinatus, as well as the euphausiids Euphausia superba and Euphausia vallentini[45] and the pelagic amphipod Themisto gaudichaudii. Sei whales have been recorded from northern Indian Ocean as well such as around Sri Lanka and Indian coasts. [39] The tail is thick and the fluke, or lobe, is relatively small in relation to the size of the whale's body. In the North Atlantic, its range extends from southern Europe or northwestern Africa to Norway, and from the southern United States to Greenland.

[10], Following large-scale commercial whaling during the late 19th and 20th centuries, when over 255,000 whales were killed,[11][12] the sei whale is now internationally protected. Fast movers when they want to be, sei whales can really ramp up the speed. The main focus of the research is to examine what they eat and to assess the competition between whales and fisheries. [69] Sei whales are commonly distributed along west to southern Latin America including along entire Chilean coasts, within Beagle Channel[70] and possibly feed in the Aysen region. A pelagic baleen whale, adults measure up to 16 metres and can live for 65 years. [38] Dorsal fin shape, pigmentation pattern, and scarring have been used to a limited extent in photo-identification studies. Rorquals take their name from the Norwegian word røyrkval, meaning "furrow whale",[23] because family members have a series of longitudinal pleats or grooves on the anterior half of their ventral surface. pp. It can reach speeds of up to 50 km/h (27 kn) over short distances. The sei whale is an aquatic mammal present in nearly all of the world’s oceans, preferring to live and travel in non-polar and non-tropical waters. Facing mounting evidence that several whale species were threatened with extinction, the IWC established a complete moratorium on commercial whaling beginning in 1986.[8]. [10] It has a single ridge extending from the tip of the rostrum to the paired blowholes that are a distinctive characteristic of baleen whales. [45][48] Some of these fish are commercially important. [9] The sei's very fine baleen bristles, about 0.1 mm (0.004 in) are the most reliable characteristic that distinguishes it from other rorquals. Sei whales inhabit all oceans and adjoining seas except in tropical and polar regions. [83], In the Southern Hemisphere, population estimates range between 9,800 and 12,000, based upon catch history and CPUE. As these species likewise became scarce, sei whale catches increased rapidly in the late 1950s and early 1960s. Sei whales favour temperate, deep offshore waters more so than other species of large whale, being rarely seen inshore. It likely functions as a contact call. The sei-whale". On the cetaceous animals. Together, we can: By adopting a whale or dolphin, by making a donation, or by fundraising for WDC, you can help us provide a safe future for these amazing creatures. The meat's value made the hunting of this difficult-to-catch species profitable in the early twentieth century. The nicknames ‘pollack whale', ‘coalfish whale' and ‘sardine whale' come from the fact that the appearance of sei whales often signalled the presence of large numbers of these fish. Animal. Later, as modern whaling shifted to Sanriku—where both species occur—it was confused for the sei whale. Discover How Long Sei whale Lives. The Sei Whale, Balaenoptera borealis, is a baleen whale, the third largest rorqual after the Blue Whale and the Fin Whale. Since the moratorium on commercial whaling, some sei whales have been taken by Icelandic and Japanese whalers under the IWC's scientific research programme. Please read our privacy policy for information on how we handle your data. [97] The IWC estimated 9,718 whales based upon survey data between 1978 and 1988. Only the larger older individuals tend to go very far south, they are relatively rare in Antarctica. SC040231, Humpback whale underwater - Vanessa Mignon, Bottlenose dolphin - Charlie Phillips/WDC. [86] [75] An individual satellite-tagged off Faial, in the Azores, traveled more than 4,000 km (2,500 mi) to the Labrador Sea via the Charlie-Gibbs Fracture Zone (CGFZ) between April and June 2005. [53], The sei whale makes long, loud, low-frequency sounds. Now the term only applies to the latter species. [8], Reaching 19.5 m (64 ft) long and weighing as much as 28 t (28 long tons; 31 short tons),[8] the sei whale consumes an average of 900 kg (2,000 lb) of food every day; its diet consists primarily of copepods, krill, and other zooplankton.

Southern Hemisphere stocks were protected in 1979. The sei whale is a baleen whale, the third-largest rorqual after the blue whale and the fin whale. Endangered Species Act. Balaenoptera borealis, the formal name of the sei whale, is most often deep gray in color with a lighter gray area covering a portion of its underside and bottom jaw. Direct comparisons of sounds in water to sounds in air can be complicated, see, Prieto, Rui, Monica A. Silva, Martine Berube, Per J. Palsbøll (2012). [76] Seven whales tagged off Faial and Pico from May to June in 2008 and 2009 made their way to the Labrador Sea, while an eighth individual tagged in September 2009 headed southeast – its signal was lost between Madeira and the Canary Islands. Sei whales are pretty adaptable. Sei whales live in all oceans, although rarely in polar or tropical waters. This rorqual is a filter feeder, using its baleen plates to obtain its food by opening its mouth, engulfing or skimming large amounts of the water containing the food, then straining the water out through the baleen, trapping any food items inside its mouth. Gray, J. E. 1846. [10][13] A 1991 study in the North Atlantic estimated only 4,000. In Japanese, the whale was called iwashi kujira, or sardine whale, a name originally applied to Bryde's whales by early Japanese whalers. In the North Atlantic, it feeds primarily on calanoid copepods, specifically Calanus finmarchicus, with a secondary preference for euphausiids, in particular Meganyctiphanes norvegica and Thysanoessa inermis. [39] In the Pacific, the whale has been called the Japan finner; "finner" was a common term used to refer to rorquals. [74], In the North Pacific, the total reported catch by commercial whalers was 72,215 between 1910 and 1975;[11] the majority were taken after 1947.

Small populations reside mainly in the Antarctic Ocean and in some parts of the Indian Ocean. [83] Japanese interests claim this figure is outdated, and in 2002 claimed the western North Pacific population was over 28,000,[88] a figure not accepted by the scientific community. Each plate is made of fingernail-like keratin, which is bordered by a fringe of very fine, short, curly, wool-like white bristles. When feeding they open their mouth and swallow a large gulp of water and prey. Very little is known about their social structure. Scroll below to learn where these magnificent ocean titans reside. [99] The drastic reduction in northeastern Atlantic copepod stocks during the late 1960s may be another culprit. Once stocks of more profitable right whales, blue whales, fin whales, and humpback whales became depleted, sei whales were hunted in earnest, particularly from 1950 to 1980. [10] The specific name is the Latin word borealis, meaning northern. The enormous size with their contrasting … Where do sei whales live? See more. These whales occur in the open ocean and generally avoid coastal waters. Large females lead the northward migration and reach the Denmark Strait earlier and more reliably than other sexes and classes, arriving in mid-July and remaining through mid-September. Perrin, William F., James G. Mead, and Robert L. Brownell, Jr. "Review of the evidence used in the description of currently recognized cetacean subspecies". To receive emails about our campaigns and how you can support them, please enter your email address below and press the ‘subscribe’ button. Balaenoptera borealis ( (northern hemisphere) and B. borealis schlegellii ( southern hemisphere), sei whale tends to follow shelf contours and plankton gatherings of aquatic/marine biomes, in temperate and subpolar regions in the summer, but migrate to sub-tropical waters during the winter. Researchers think this may be a response to the predation rate. Quotas on sei whales in the North Atlantic began in 1977. You can unsubscribe at any time. At the end of the day that's what counted at the time. The sei whale can be found swimming in all of the worlds major oceans, however certain populations may be more abundant than others. As of February 2017[update], the U.S. National Marine Fisheries Service estimated that the eastern North Pacific population stood at 374 whales. [6] More than 2,000 were caught in British Columbian waters between 1962 and 1967. (2006). Like other great whales, they prefer to spend the summer feeding in cooler waters before migrating to … The different estimates result from scientists' inability to observe an entire pregnancy; most reproductive data for baleen whales were obtained from animals caught by commercial whalers, which offer only single snapshots of fetal growth. [65] In Sea of Japan and Sea of Okhotsk, whales are not common, although whales were more commonly seen than today in southern part of Sea of Japan from Korean Peninsula to the southern Primorsky Krai in the past, and there had been a sighting in Golden Horn Bay,[66] and whales were much more abundant in the triangle area around Kunashir Island in whaling days, making the area well known as sei – ground,[67] and there had been a sighting of a cow calf pair off the Sea of Japan coast of mid-Honshu during cetacean survey. [15][16] It has also been referred to as the lesser fin whale because it somewhat resembles the fin whale. Sei whales live in all oceans and seas, except tropical and polar regions. In the late 1970s, some "pirate" whaling took place in the eastern North Atlantic. It inhabits most oceans and adjoining seas, and prefers deep offshore waters. Sei whale usually resides in temperate waters, away from the shore. [29][30][31] The largest specimens taken off Iceland were a 16.15 m (53.0 ft) female and a 14.6 m (48 ft) male, while the longest off Nova Scotia were two 15.8 m (52 ft) females and a 15.2 m (50 ft) male. Sei Whales are found from subtropical to subpolar regions but in deep water and offshore. [54] An observer situated one metre from a vocalizing whale would perceive a volume roughly equivalent to the volume of a jackhammer operating two metres away. [97][98] Sei whales were said to have been scarce in the 1960s and early 1970s off northern Norway. Run, bake, walk, cycle… what could you do for whales and dolphins? Minke Whale – There are two known species of minke whales currently in existence, the common or north Atlantic minke whale (which inhibits the north Atlantic waters) and the Antarctic or southern minke whale (which lives in the Antarctic region south of the equator). Do Sei whale have teeth? I didn't think it was really nice to do that. [25] Their ranges do not overlap. [9] The whale's name comes from the Norwegian word for pollock, a fish that appears off the coast of Norway at the same time of the year as the sei whale. Where do sei whales live? How long does a Sei whale live? The research is conducted by the Institute of Cetacean Research (ICR) in Tokyo, a privately funded, nonprofit institution. [97], Mass death events for sei whales have been recorded for many years and evidence suggests endemic poisoning (red tide) causes may have caused mass deaths in prehistoric times. [9] In the Northern Hemisphere, males are usually 12.8–12.9 m (42–42 ft) and females 13.3–13.5 m (44–44 ft) at sexual maturity, while in the Southern Hemisphere, males average 13.6 m (45 ft) and females 14 m (46 ft). and Christian T. Chimimba. The species remained listed on the IUCN Red List of Threatened Species in 2000, categorized as "endangered". [6], In the North Atlantic between 1885 and 1984, 14,295 sei whales were taken. [83] By the end of whaling, the population was down to between 7,260 and 12,620. They also avoid bodies of water that are semi-enclosed. [31], Despite knowing some general migration patterns, exact routes are incompletely known[31] and scientists cannot readily predict exactly where groups will appear from one year to the next. Since the late 1960s to early 1970s, the sei whale has been second only to the fin whale as the preferred target of Icelandic whalers, with meat in greater demand than whale oil, the prior target. During the colder winter months these whales will travel towar… Growing up to 19.5 metres long, female sei whales are the larger of the two sexes, eclipsing their male counterparts by over 2 metres. They are found in nearly all of the world’s waters from the sub-Arctic and sub-Antarctic, apart from the Mediterranean and Baltic seas. You will find the Sei Whale living in most of the oceans as well as the seas that are adjoined to them. They are found in nearly all of the world’s waters from the sub-Arctic and sub-Antarctic, apart from the Mediterranean and Baltic seas. They are found like many whales in both Northern and Southern hemispheres following the best feeding at different times of year. It appeared to "hitch a ride" on prevailing currents, with erratic movements indicative of feeding behavior in five areas, in particular the CGFZ, an area of known high sei whale abundance as well as high copepod concentrations. [11] Whaling in southern oceans originally targeted humpback whales. Between dives, the whale surfaces for a few minutes, remaining visible in clear, calm waters, with blows occurring at intervals of about 60 seconds (range: 45–90 sec.). Registered Charity (Scotland) No. A newborn is weaned from its mother at 6–9 months of age, when it is 8–9 m (26–30 ft) long,[28] so weaning takes place at the summer or autumn feeding grounds. The sei whale is among the fastest cetaceans. The whale's body is typically a dark steel grey with irregular light grey to white markings on the ventral surface, or towards the front of the lower body. Reaching speeds up to 34.5 miles per hour makes the Sei Whale the fast whale in the water. OUR DATA: We use the most recent data from these primary sources: AnAge, UMICH, Max Planck, PanTHERIA, Arkive, UKC, AKC. During the summer, they are commonly found in the Gulf of Maine, and on Georges Bank and Stellwagen Bank off the U.S. coast in the western North Atlantic. [82] Shore stations in Japan and Korea processed 300–600 each year between 1911 and 1955. The whale's diet preferences has been determined from stomach analyses, direct observation of feeding behavior,[42][43] and analyzing fecal matter collected near them, which appears as a dilute brown cloud. Sei whales appeared off the coast of Norway at the same time as the pollock, both coming to feed on the abundant plankton. [91]. Sei whales, an endangered species, can grow to 65 feet and live as long as 70 years. The bodies of sei whales range in colouring from murky blues to steely greys to deep browns. Researchers attempt to extrapolate conception dates by comparing fetus size and characteristics with newborns. You also have the option to opt-out of these cookies. Other names: Rudolphi's rorqual; Japan finner' Sardine whale; Coalfish whale. [8] The difficulty of distinguishing them at sea from their close relatives, Bryde's whales and in some cases from fin whales, creates confusion about their range and population, especially in warmer waters where Bryde's whales are most common. [72] In the northeast Atlantic, the sei whale winters as far south as West Africa such as off Bay of Arguin, off coastal Western Sahara and follows the continental slope northward in spring. [26] ([27] In the Northern Hemisphere, males reach up to 17.1 m (56 ft) and females up to 18.6 m (61 ft),[28] while in the Southern Hemisphere males reach 18.6 m (61 ft) and females 19.5 m (64 ft)—the authenticity of an alleged 22 m (72 ft) female caught 50 miles northwest of St. Kilda in July 1911 is doubted. Most common in the southern hemisphere, they prefer deep waters and will only approach shores around islands. They eat krill, squid, and small schooling fish by lunge diving or by skimming the water. These calls averaged 82.3 Hz down to 34 Hz over about 1.4 seconds in duration. One whale would always leave the group during or immediately after such socializing bouts. The Sei Whales (pronounced “say”) you might see on your Antarctica cruise are another example of a speedy whale. Adult Sei whales can weigh between 20 and 30 tonnes and grow up to 19.5m in length. The Sei whales body is typically a dark steel grey with irregular light grey to white markings on the ventral surface, or towards the front of the lower body. They prefer temperate waters in the mid-latitudes, and can be found in the Atlantic, Indian, and Pacific Oceans. Sometimes breaching, their bodies leave the water at a low angle and finish with a graceful belly flop. The 33ft mammal, thought to be a Sei whale, was discovered in salt marshes on the north bank of the River Humber near the village of Skeffling. A world where every whale and dolphin is safe and free. Prior to commercial whaling, the North Pacific hosted an estimated 42,000. [13][14], Sei is the Norwegian word for pollock, also referred to as coalfish, a close relative of codfish. Sei whales live in all oceans, although rarely in polar or tropical waters. [27] The average age of sexual maturity of both sexes is 8–10 years. They occupy sub-polar and temperate regions during the summer, migrating to sub-tropical waters in the winter. Along their heads, a single ridge runs from the tip of the nose to  two blowholes and set  aloft  their backs is a sickle-shaped dorsal fin. Sei whales don’t gulp-feed like the other whales in their family. The sei whale is a baleen whale and it lives in most oceans and seas but prefers deep off shore waters. [49] In the Southern Hemisphere, prey species include the copepods Neocalanus tonsus, Calanus simillimus, and Drepanopus pectinatus, as well as the euphausiids Euphausia superba and Euphausia vallentini[45] and the pelagic amphipod Themisto gaudichaudii. Sei whales have been recorded from northern Indian Ocean as well such as around Sri Lanka and Indian coasts. [39] The tail is thick and the fluke, or lobe, is relatively small in relation to the size of the whale's body. In the North Atlantic, its range extends from southern Europe or northwestern Africa to Norway, and from the southern United States to Greenland.

[10], Following large-scale commercial whaling during the late 19th and 20th centuries, when over 255,000 whales were killed,[11][12] the sei whale is now internationally protected. Fast movers when they want to be, sei whales can really ramp up the speed. The main focus of the research is to examine what they eat and to assess the competition between whales and fisheries. [69] Sei whales are commonly distributed along west to southern Latin America including along entire Chilean coasts, within Beagle Channel[70] and possibly feed in the Aysen region. A pelagic baleen whale, adults measure up to 16 metres and can live for 65 years. [38] Dorsal fin shape, pigmentation pattern, and scarring have been used to a limited extent in photo-identification studies. Rorquals take their name from the Norwegian word røyrkval, meaning "furrow whale",[23] because family members have a series of longitudinal pleats or grooves on the anterior half of their ventral surface. pp. It can reach speeds of up to 50 km/h (27 kn) over short distances. The sei whale is an aquatic mammal present in nearly all of the world’s oceans, preferring to live and travel in non-polar and non-tropical waters. Facing mounting evidence that several whale species were threatened with extinction, the IWC established a complete moratorium on commercial whaling beginning in 1986.[8]. [10] It has a single ridge extending from the tip of the rostrum to the paired blowholes that are a distinctive characteristic of baleen whales. [45][48] Some of these fish are commercially important. [9] The sei's very fine baleen bristles, about 0.1 mm (0.004 in) are the most reliable characteristic that distinguishes it from other rorquals. Sei whales inhabit all oceans and adjoining seas except in tropical and polar regions. [83], In the Southern Hemisphere, population estimates range between 9,800 and 12,000, based upon catch history and CPUE. As these species likewise became scarce, sei whale catches increased rapidly in the late 1950s and early 1960s. Sei whales favour temperate, deep offshore waters more so than other species of large whale, being rarely seen inshore. It likely functions as a contact call. The sei-whale". On the cetaceous animals. Together, we can: By adopting a whale or dolphin, by making a donation, or by fundraising for WDC, you can help us provide a safe future for these amazing creatures. The meat's value made the hunting of this difficult-to-catch species profitable in the early twentieth century. The nicknames ‘pollack whale', ‘coalfish whale' and ‘sardine whale' come from the fact that the appearance of sei whales often signalled the presence of large numbers of these fish. Animal. Later, as modern whaling shifted to Sanriku—where both species occur—it was confused for the sei whale. Discover How Long Sei whale Lives. The Sei Whale, Balaenoptera borealis, is a baleen whale, the third largest rorqual after the Blue Whale and the Fin Whale. Since the moratorium on commercial whaling, some sei whales have been taken by Icelandic and Japanese whalers under the IWC's scientific research programme. Please read our privacy policy for information on how we handle your data. [97] The IWC estimated 9,718 whales based upon survey data between 1978 and 1988. Only the larger older individuals tend to go very far south, they are relatively rare in Antarctica. SC040231, Humpback whale underwater - Vanessa Mignon, Bottlenose dolphin - Charlie Phillips/WDC. [86] [75] An individual satellite-tagged off Faial, in the Azores, traveled more than 4,000 km (2,500 mi) to the Labrador Sea via the Charlie-Gibbs Fracture Zone (CGFZ) between April and June 2005. [53], The sei whale makes long, loud, low-frequency sounds. Now the term only applies to the latter species. [8], Reaching 19.5 m (64 ft) long and weighing as much as 28 t (28 long tons; 31 short tons),[8] the sei whale consumes an average of 900 kg (2,000 lb) of food every day; its diet consists primarily of copepods, krill, and other zooplankton.

[100] Nova Scotia's population estimates are between 1,393 and 2,248, with a minimum of 870. The only confirmed historical record is the capture of a 14 m (46 ft) female, which was brought to the Cap Lopez whaling station in Gabon in September 1950. This call has also been reported from recordings in the Gulf of Maine, New England shelf waters, the mid-Atlantic Bight, and in Davis Strait. yes the sei whale does live with a pack I just found out google Where does the sei whale live? [2] The majority of the "sei" whales caught off Angola and Congo, as well as other nearby areas in equatorial West Africa, are thought to have been predominantly misidentified Bryde's whales. Recent Examples on the Web The sei whale, a somewhat mysterious type of whale that prefer to live in temperate waters in the mid-latitudes, was not yet mature, marine mammal biologists say. Most calls lasted about a half second, and occurred in the 240–625 hertz range, well within the range of human hearing. [8] In the northwest Atlantic, sightings and catch records suggest the whales move north along the shelf edge to arrive in the areas of Georges Bank, Northeast Channel, and Browns Bank by mid- to late June. [78], Small numbers were taken off the Iberian Peninsula, beginning in the 1920s by Spanish whalers,[81] off the Nova Scotian shelf in the late 1960s and early 1970s by Canadian whalers,[72] and off the coast of West Greenland from the 1920s to the 1950s by Norwegian and Danish whalers. Large individuals can be confused with fin whales, unless the fin whale's asymmetrical head coloration is clearly seen. The Swedish-born German naturalist Karl Rudolphi initially identified it as Balaena rostrata (=Balaenoptera acutorostrata). [8], Sei whales usually travel alone[41] or in pods of up to six individuals. Humans kill a great many whales each year, and this might have effects on their reproductive activity. All the calls were downswept tonal calls, all but two ranging from a mean high frequency of 39.1 Hz down to 21 Hz of 1.3 second duration – the two higher frequency downswept calls ranged from an average of 100.3 Hz to 44.6 Hz over 1 second of duration. View all. For example, Ruud (1952) found that 42 of the "sei whale" catch off Gabon in 1952 were actually Bryde's whales, based on examination of their baleen plates. Sei whales rarely dive deeper than 300m, or for more than 20 minutes, as their prey is usually found quite close to the surface. When they need to they can burst up to speeds in the neighbourhood of 80 km per hour for short distances, making them one of the fastest cetaceans in the seas. The difficulty of distinguishing them at sea from their close relatives, Bryde's whales and in some cases from fin whales, creates confusion about their range and population, especially in warmer waters where Bryde's whales are most common. [45] The catch peaked in 1964–65 at over 20,000 sei whales, but by 1976, this number had dropped to below 2,000 and commercial whaling for the species ended in 1977.[6]. Heavy exploitation in the North Pacific began in the early 1960s, with catches averaging 3,643 per year from 1963 to 1974 (total 43,719; annual range 1,280–6,053). Registered Charity (England and Wales) No. Whales in the Labrador Sea as early as the first week of June may move farther northward to waters southwest of Greenland later in the summer. [9] It is among the fastest of all cetaceans, and can reach speeds of up to 50 km/h (31 mph) (27 knots) over short distances. Blue whales are truly majestic giants of the ocean. Conservation status: Endangered. Keep up-to-date with all the news from WDC and the world of whales and dolphins. "Migratory destinations and sex composition of sei whales (, Pacific Islands Cetaceans Memorandum of Understanding, 10.2305/IUCN.UK.2008.RLTS.T2475A9445100.en, https://ecos.fws.gov/ecp0/profile/speciesProfile?sId=4753, "Special Issue: The Great Whales: History and Status of Six Species Listed as Endangered Under the U.S. The Sei whale could be confused with the Bryde’s whale, but it does not arch its back as much as the Bryde’s when it blows, so at the surface the whale appears very gentle when appearing or when disappearing.. In addition, it eats larger organisms, such as the Japanese flying squid, Todarodes pacificus pacificus,[47] and small fish, including anchovies (Engraulis japonicus and E. mordax), sardines (Sardinops sagax), Pacific saury (Cololabis saira), mackerel (Scomber japonicus and S. australasicus), jack mackerel (Trachurus symmetricus) and juvenile rockfish (Sebastes jordani). Dr. Seiji Ohsumi, Director General of the ICR, said, Conservation groups, such as the World Wildlife Fund, dispute the value of this research, claiming that sei whales feed primarily on squid and plankton which are not hunted by humans, and only rarely on fish. [57], BBC News quoted Roddy Morrison, a former whaler active in South Georgia, as saying, "When we killed the sei whales, they used to make a noise, like a crying noise. [11] They were hunted in large numbers off the coasts of Norway and Scotland beginning in the late 19th and early 20th centuries,[73] and in 1885 alone, more than 700 were caught off Finnmark. These calls closely resembled and coincided with a peak in "20- to 35-Hz irregular repetition interval" downswept pulses described from seafloor recordings off Oahu, which had previously been attributed to fin whales. [49] Commercial Sei whaling ended in the eastern North Pacific in 1971. The feces are collected in nets and DNA is separated, individually identified, and matched with known species. The sei became endangered when it was heavily hunted after the stocks of blue and fin whales became depleted and it now has a population of about 12,000, according to the WWF. Usually seen in small groups, numbers of sei whales will often increase when food sources are plentiful. Feeding in colder waters in summer, it is believed that they turn tail in winter and migrate to warmer, lower latitudes. They aren’t often seen though as they tend to stay in the deeper waters offshore. Sei whale is covered by the Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region (Pacific Cetaceans MOU) and the Agreement on the Conservation of Small Cetaceans of the Baltic, North East Atlantic, Irish and North Seas (ASCOBAMS). Sei whales typically live far out from coastlines in deep ocean waters. The sei whale is a baleen whale, the third-largest rorqual after the blue whale and the fin whale. The sei whale (/ˈseɪ/,[4][5] Balaenoptera borealis) is a baleen whale, the third-largest rorqual after the blue whale and the fin whale. [10], Adults have 300–380 ashy-black baleen plates on each side of the mouth, up to 80 cm (31 in) long. [40], The sei whale looks very similar to other large rorquals, especially its smaller relative the Bryde's whale. They have baleen as do the Grey Whales that are often seen from shore.

The sei whale is a baleen whale, the third-largest rorqual after the blue whale and the fin whale. Endangered Species Act. Balaenoptera borealis, the formal name of the sei whale, is most often deep gray in color with a lighter gray area covering a portion of its underside and bottom jaw. Direct comparisons of sounds in water to sounds in air can be complicated, see, Prieto, Rui, Monica A. Silva, Martine Berube, Per J. Palsbøll (2012). [76] Seven whales tagged off Faial and Pico from May to June in 2008 and 2009 made their way to the Labrador Sea, while an eighth individual tagged in September 2009 headed southeast – its signal was lost between Madeira and the Canary Islands. Sei whales are pretty adaptable. Sei whales live in all oceans, although rarely in polar or tropical waters. This rorqual is a filter feeder, using its baleen plates to obtain its food by opening its mouth, engulfing or skimming large amounts of the water containing the food, then straining the water out through the baleen, trapping any food items inside its mouth. Gray, J. E. 1846. [10][13] A 1991 study in the North Atlantic estimated only 4,000. In Japanese, the whale was called iwashi kujira, or sardine whale, a name originally applied to Bryde's whales by early Japanese whalers. In the North Atlantic, it feeds primarily on calanoid copepods, specifically Calanus finmarchicus, with a secondary preference for euphausiids, in particular Meganyctiphanes norvegica and Thysanoessa inermis. [39] In the Pacific, the whale has been called the Japan finner; "finner" was a common term used to refer to rorquals. [74], In the North Pacific, the total reported catch by commercial whalers was 72,215 between 1910 and 1975;[11] the majority were taken after 1947.

Small populations reside mainly in the Antarctic Ocean and in some parts of the Indian Ocean. [83] Japanese interests claim this figure is outdated, and in 2002 claimed the western North Pacific population was over 28,000,[88] a figure not accepted by the scientific community. Each plate is made of fingernail-like keratin, which is bordered by a fringe of very fine, short, curly, wool-like white bristles. When feeding they open their mouth and swallow a large gulp of water and prey. Very little is known about their social structure. Scroll below to learn where these magnificent ocean titans reside. [99] The drastic reduction in northeastern Atlantic copepod stocks during the late 1960s may be another culprit. Once stocks of more profitable right whales, blue whales, fin whales, and humpback whales became depleted, sei whales were hunted in earnest, particularly from 1950 to 1980. [10] The specific name is the Latin word borealis, meaning northern. The enormous size with their contrasting … Where do sei whales live? See more. These whales occur in the open ocean and generally avoid coastal waters. Large females lead the northward migration and reach the Denmark Strait earlier and more reliably than other sexes and classes, arriving in mid-July and remaining through mid-September. Perrin, William F., James G. Mead, and Robert L. Brownell, Jr. "Review of the evidence used in the description of currently recognized cetacean subspecies". To receive emails about our campaigns and how you can support them, please enter your email address below and press the ‘subscribe’ button. Balaenoptera borealis ( (northern hemisphere) and B. borealis schlegellii ( southern hemisphere), sei whale tends to follow shelf contours and plankton gatherings of aquatic/marine biomes, in temperate and subpolar regions in the summer, but migrate to sub-tropical waters during the winter. Researchers think this may be a response to the predation rate. Quotas on sei whales in the North Atlantic began in 1977. You can unsubscribe at any time. At the end of the day that's what counted at the time. The sei whale can be found swimming in all of the worlds major oceans, however certain populations may be more abundant than others. As of February 2017[update], the U.S. National Marine Fisheries Service estimated that the eastern North Pacific population stood at 374 whales. [6] More than 2,000 were caught in British Columbian waters between 1962 and 1967. (2006). Like other great whales, they prefer to spend the summer feeding in cooler waters before migrating to … The different estimates result from scientists' inability to observe an entire pregnancy; most reproductive data for baleen whales were obtained from animals caught by commercial whalers, which offer only single snapshots of fetal growth. [65] In Sea of Japan and Sea of Okhotsk, whales are not common, although whales were more commonly seen than today in southern part of Sea of Japan from Korean Peninsula to the southern Primorsky Krai in the past, and there had been a sighting in Golden Horn Bay,[66] and whales were much more abundant in the triangle area around Kunashir Island in whaling days, making the area well known as sei – ground,[67] and there had been a sighting of a cow calf pair off the Sea of Japan coast of mid-Honshu during cetacean survey. [15][16] It has also been referred to as the lesser fin whale because it somewhat resembles the fin whale. Sei whales live in all oceans and seas, except tropical and polar regions. In the late 1970s, some "pirate" whaling took place in the eastern North Atlantic. It inhabits most oceans and adjoining seas, and prefers deep offshore waters. Sei whale usually resides in temperate waters, away from the shore. [29][30][31] The largest specimens taken off Iceland were a 16.15 m (53.0 ft) female and a 14.6 m (48 ft) male, while the longest off Nova Scotia were two 15.8 m (52 ft) females and a 15.2 m (50 ft) male. Sei Whales are found from subtropical to subpolar regions but in deep water and offshore. [54] An observer situated one metre from a vocalizing whale would perceive a volume roughly equivalent to the volume of a jackhammer operating two metres away. [97][98] Sei whales were said to have been scarce in the 1960s and early 1970s off northern Norway. Run, bake, walk, cycle… what could you do for whales and dolphins? Minke Whale – There are two known species of minke whales currently in existence, the common or north Atlantic minke whale (which inhibits the north Atlantic waters) and the Antarctic or southern minke whale (which lives in the Antarctic region south of the equator). Do Sei whale have teeth? I didn't think it was really nice to do that. [25] Their ranges do not overlap. [9] The whale's name comes from the Norwegian word for pollock, a fish that appears off the coast of Norway at the same time of the year as the sei whale. Where do sei whales live? How long does a Sei whale live? The research is conducted by the Institute of Cetacean Research (ICR) in Tokyo, a privately funded, nonprofit institution. [97], Mass death events for sei whales have been recorded for many years and evidence suggests endemic poisoning (red tide) causes may have caused mass deaths in prehistoric times. [9] In the Northern Hemisphere, males are usually 12.8–12.9 m (42–42 ft) and females 13.3–13.5 m (44–44 ft) at sexual maturity, while in the Southern Hemisphere, males average 13.6 m (45 ft) and females 14 m (46 ft). and Christian T. Chimimba. The species remained listed on the IUCN Red List of Threatened Species in 2000, categorized as "endangered". [6], In the North Atlantic between 1885 and 1984, 14,295 sei whales were taken. [83] By the end of whaling, the population was down to between 7,260 and 12,620. They also avoid bodies of water that are semi-enclosed. [31], Despite knowing some general migration patterns, exact routes are incompletely known[31] and scientists cannot readily predict exactly where groups will appear from one year to the next. Since the late 1960s to early 1970s, the sei whale has been second only to the fin whale as the preferred target of Icelandic whalers, with meat in greater demand than whale oil, the prior target. During the colder winter months these whales will travel towar… Growing up to 19.5 metres long, female sei whales are the larger of the two sexes, eclipsing their male counterparts by over 2 metres. They are found in nearly all of the world’s waters from the sub-Arctic and sub-Antarctic, apart from the Mediterranean and Baltic seas. You will find the Sei Whale living in most of the oceans as well as the seas that are adjoined to them. They are found in nearly all of the world’s waters from the sub-Arctic and sub-Antarctic, apart from the Mediterranean and Baltic seas. They are found like many whales in both Northern and Southern hemispheres following the best feeding at different times of year. It appeared to "hitch a ride" on prevailing currents, with erratic movements indicative of feeding behavior in five areas, in particular the CGFZ, an area of known high sei whale abundance as well as high copepod concentrations. [11] Whaling in southern oceans originally targeted humpback whales. Between dives, the whale surfaces for a few minutes, remaining visible in clear, calm waters, with blows occurring at intervals of about 60 seconds (range: 45–90 sec.). Registered Charity (Scotland) No. A newborn is weaned from its mother at 6–9 months of age, when it is 8–9 m (26–30 ft) long,[28] so weaning takes place at the summer or autumn feeding grounds. The sei whale is among the fastest cetaceans. The whale's body is typically a dark steel grey with irregular light grey to white markings on the ventral surface, or towards the front of the lower body. Reaching speeds up to 34.5 miles per hour makes the Sei Whale the fast whale in the water. OUR DATA: We use the most recent data from these primary sources: AnAge, UMICH, Max Planck, PanTHERIA, Arkive, UKC, AKC. During the summer, they are commonly found in the Gulf of Maine, and on Georges Bank and Stellwagen Bank off the U.S. coast in the western North Atlantic. [82] Shore stations in Japan and Korea processed 300–600 each year between 1911 and 1955. The whale's diet preferences has been determined from stomach analyses, direct observation of feeding behavior,[42][43] and analyzing fecal matter collected near them, which appears as a dilute brown cloud. Sei whales appeared off the coast of Norway at the same time as the pollock, both coming to feed on the abundant plankton. [91]. Sei whales, an endangered species, can grow to 65 feet and live as long as 70 years. The bodies of sei whales range in colouring from murky blues to steely greys to deep browns. Researchers attempt to extrapolate conception dates by comparing fetus size and characteristics with newborns. You also have the option to opt-out of these cookies. Other names: Rudolphi's rorqual; Japan finner' Sardine whale; Coalfish whale. [8] The difficulty of distinguishing them at sea from their close relatives, Bryde's whales and in some cases from fin whales, creates confusion about their range and population, especially in warmer waters where Bryde's whales are most common. [72] In the northeast Atlantic, the sei whale winters as far south as West Africa such as off Bay of Arguin, off coastal Western Sahara and follows the continental slope northward in spring. [26] ([27] In the Northern Hemisphere, males reach up to 17.1 m (56 ft) and females up to 18.6 m (61 ft),[28] while in the Southern Hemisphere males reach 18.6 m (61 ft) and females 19.5 m (64 ft)—the authenticity of an alleged 22 m (72 ft) female caught 50 miles northwest of St. Kilda in July 1911 is doubted. Most common in the southern hemisphere, they prefer deep waters and will only approach shores around islands. They eat krill, squid, and small schooling fish by lunge diving or by skimming the water. These calls averaged 82.3 Hz down to 34 Hz over about 1.4 seconds in duration. One whale would always leave the group during or immediately after such socializing bouts. The Sei Whales (pronounced “say”) you might see on your Antarctica cruise are another example of a speedy whale. Adult Sei whales can weigh between 20 and 30 tonnes and grow up to 19.5m in length. The Sei whales body is typically a dark steel grey with irregular light grey to white markings on the ventral surface, or towards the front of the lower body. They prefer temperate waters in the mid-latitudes, and can be found in the Atlantic, Indian, and Pacific Oceans. Sometimes breaching, their bodies leave the water at a low angle and finish with a graceful belly flop. The 33ft mammal, thought to be a Sei whale, was discovered in salt marshes on the north bank of the River Humber near the village of Skeffling. A world where every whale and dolphin is safe and free. Prior to commercial whaling, the North Pacific hosted an estimated 42,000. [13][14], Sei is the Norwegian word for pollock, also referred to as coalfish, a close relative of codfish. Sei whales live in all oceans, although rarely in polar or tropical waters. [27] The average age of sexual maturity of both sexes is 8–10 years. They occupy sub-polar and temperate regions during the summer, migrating to sub-tropical waters in the winter. Along their heads, a single ridge runs from the tip of the nose to  two blowholes and set  aloft  their backs is a sickle-shaped dorsal fin. Sei whales don’t gulp-feed like the other whales in their family. The sei whale is a baleen whale and it lives in most oceans and seas but prefers deep off shore waters. [49] In the Southern Hemisphere, prey species include the copepods Neocalanus tonsus, Calanus simillimus, and Drepanopus pectinatus, as well as the euphausiids Euphausia superba and Euphausia vallentini[45] and the pelagic amphipod Themisto gaudichaudii. Sei whales have been recorded from northern Indian Ocean as well such as around Sri Lanka and Indian coasts. [39] The tail is thick and the fluke, or lobe, is relatively small in relation to the size of the whale's body. In the North Atlantic, its range extends from southern Europe or northwestern Africa to Norway, and from the southern United States to Greenland.

[10], Following large-scale commercial whaling during the late 19th and 20th centuries, when over 255,000 whales were killed,[11][12] the sei whale is now internationally protected. Fast movers when they want to be, sei whales can really ramp up the speed. The main focus of the research is to examine what they eat and to assess the competition between whales and fisheries. [69] Sei whales are commonly distributed along west to southern Latin America including along entire Chilean coasts, within Beagle Channel[70] and possibly feed in the Aysen region. A pelagic baleen whale, adults measure up to 16 metres and can live for 65 years. [38] Dorsal fin shape, pigmentation pattern, and scarring have been used to a limited extent in photo-identification studies. Rorquals take their name from the Norwegian word røyrkval, meaning "furrow whale",[23] because family members have a series of longitudinal pleats or grooves on the anterior half of their ventral surface. pp. It can reach speeds of up to 50 km/h (27 kn) over short distances. The sei whale is an aquatic mammal present in nearly all of the world’s oceans, preferring to live and travel in non-polar and non-tropical waters. Facing mounting evidence that several whale species were threatened with extinction, the IWC established a complete moratorium on commercial whaling beginning in 1986.[8]. [10] It has a single ridge extending from the tip of the rostrum to the paired blowholes that are a distinctive characteristic of baleen whales. [45][48] Some of these fish are commercially important. [9] The sei's very fine baleen bristles, about 0.1 mm (0.004 in) are the most reliable characteristic that distinguishes it from other rorquals. Sei whales inhabit all oceans and adjoining seas except in tropical and polar regions. [83], In the Southern Hemisphere, population estimates range between 9,800 and 12,000, based upon catch history and CPUE. As these species likewise became scarce, sei whale catches increased rapidly in the late 1950s and early 1960s. Sei whales favour temperate, deep offshore waters more so than other species of large whale, being rarely seen inshore. It likely functions as a contact call. The sei-whale". On the cetaceous animals. Together, we can: By adopting a whale or dolphin, by making a donation, or by fundraising for WDC, you can help us provide a safe future for these amazing creatures. The meat's value made the hunting of this difficult-to-catch species profitable in the early twentieth century. The nicknames ‘pollack whale', ‘coalfish whale' and ‘sardine whale' come from the fact that the appearance of sei whales often signalled the presence of large numbers of these fish. Animal. Later, as modern whaling shifted to Sanriku—where both species occur—it was confused for the sei whale. Discover How Long Sei whale Lives. The Sei Whale, Balaenoptera borealis, is a baleen whale, the third largest rorqual after the Blue Whale and the Fin Whale. Since the moratorium on commercial whaling, some sei whales have been taken by Icelandic and Japanese whalers under the IWC's scientific research programme. Please read our privacy policy for information on how we handle your data. [97] The IWC estimated 9,718 whales based upon survey data between 1978 and 1988. Only the larger older individuals tend to go very far south, they are relatively rare in Antarctica. SC040231, Humpback whale underwater - Vanessa Mignon, Bottlenose dolphin - Charlie Phillips/WDC. [86] [75] An individual satellite-tagged off Faial, in the Azores, traveled more than 4,000 km (2,500 mi) to the Labrador Sea via the Charlie-Gibbs Fracture Zone (CGFZ) between April and June 2005. [53], The sei whale makes long, loud, low-frequency sounds. Now the term only applies to the latter species. [8], Reaching 19.5 m (64 ft) long and weighing as much as 28 t (28 long tons; 31 short tons),[8] the sei whale consumes an average of 900 kg (2,000 lb) of food every day; its diet consists primarily of copepods, krill, and other zooplankton.
