In Burns, J. J.; Montague, J. J.; and Cowles, C. J. Woodby, D. A. and D. B. Botkin (1993). According to Russian scientists, this total population likely does not exceed 400 animals. Bowhead whale belongs to the group of baleen whales. [50], Not much is known about the endangered Sea of Okhotsk population. [85], Commercial bowhead whaling began in the 16th century when the Basques killed them as they migrated south through the Strait of Belle Isle in the fall and early winter. Indigenous whaling is carried out through a co-management agreement between the Alaska Eskimo Whaling Commission and National Marine Fisheries Service, with oversight by the International Whaling Commission. The Alaskan population spends the winter months in the southwestern Bering Sea. [37] The whale's range varies depending on climate changes and on the forming/melting of ice. [33] The whale's genome may also reveal physiological adaptations such as having low metabolic rates compared to other mammals. During 1858–1860, the ships shifted back to the Bering Strait region, where the majority of the fleet cruised during the summer until the early 20th century. [25] The diet consists of mostly zooplankton, which includes copepods, amphipods, and many other crustaceans. The largest and most well-studied population is found off Alaska and Russia in the Bering, Chukchi and Beaufort Seas. Ice-covered areas have frequently been interpreted as preferred bowhead foraging habitat in analyses that did not as-sess effects of predators. [45], The status of other populations is less well known. The whale's range varies depending on climate changes and on the forming/melting of ice. The bowhead whale is the only baleen whale to spend its entire life in the Arctic and subarctic waters. A newborn calf is typically 4–4.5 m (13–15 ft) long, weighs roughly 1,000 kg (2,200 lb), and grows to 8.2 m (27 ft) within the first year. Here they make highly variable seasonal migrations between coastal areas and offshore waters. We sought to determine when and where different demographic groups of Eastern Canada-West Greenland bowhead … It also has the largest mouth of any animal in the world. By midcentury, the population(s) there had practically been wiped out, forcing whalers to voyage into the "West Ice"—the pack ice off Greenland's east coast. Surfaces shown are habitat selection predictions under different distances to killer whale predators, … [40], Generally, five stocks of bowhead whales are recognized: 1) The Western Arctic stock in the Bering, Chukchi, and Beaufort Seas, 2) The Hudson Bay and Foxe Basin stock, 3) The Baffin Bay and Davis Strait stock, 4) The Sea of Okhotsk stock, and 5) The Svalbard-Barents Sea stock. Reilly, S.B., Bannister, J.L., Best, P.B., Brown, M., Brownell Jr., R.L., Butterworth, D.S., Clapham, P.J., Cooke, J., Donovan, G., Urbán, J. [24] About 2 short tons (1.8 long tons; 1.8 t) of food are consumed each day. The Bowhead whale was named for its distinctive bow-shaped skull, which is enormous—close to 40 percent of total body length can grow up to 20 metres in length. They have an average length of 15 to 18 m (49 to 59 ft) but have been reported up to 20 m (65 ft), and can weigh up to 100 tonnes (220,462 lb). This organ is thought to provide a mechanism of cooling for the whale (which is normally protected from the cold Arctic waters by 40 cm (16 in) or more of fat). The Alaskan population winter in the southwestern Bering Sea. The bulbous ridge of highly vascularized tissue, the corpus cavernosum maxillaris, extends along the centre of the hard plate, forming two large lobes at the rostral palate. Thirty-three bowhead whale carcasses were documented in July–October, from 2009 to 2018. An unknown species of right whale, the so-called "Swedenborg whale", which was proposed by Emanuel Swedenborg in the 18th century, was once thought to be a North Atlantic right whale by scientific consensus. However, moultings have not been recorded in this area due to environmental factors. [34] Through comparative analysis, two alleles that could be responsible for the whale's longevity were identified. ", "Ancient DNA reveals that bowhead whale lineages survived Late Pleistocene climate change and habitat shifts", "Bowhead Whales, and Not Right Whales, Were the Primary Target of 16th- to 17th-Century Basque Whalers in the Western North Atlantic", "The oldest marine vertebrate fossil from the volcanic island of Iceland: a partial right whale skull from the high latitude Pliocene Tjörnes Formation", "Bowhead Whale: Western Arctic Stock (December 30 2015)", Eastern Arctic bowhead whales not threatened, "Foraging Ecology of Bowhead Whales in West Greenland. One individual caught of the coast of Alaska in 2007 was found to have a harpoon point embedded in it that dated back to 1880, … The bowhead whale (Balaena mysticetus), or Greenland right whale, is a baleen whale of Arctic seas. [9] It was seemingly identical to its relatives in the North Atlantic, North Pacific, and Southern Oceans, and as such they were all thought to be a single species, collectively known as the "right whale", and given the binomial name Balaena mysticetus. It inhabits cold waters of the Arctic sea. Based on later DNA analysis, those fossil bones claimed to be from Swedenborg whales were confirmed to be from bowhead whales. [20] Lactation typically lasts about a year. By 1719, they had reached the Davis Strait, and by the first quarter of the 19th century, Baffin Bay. Habitat and Distribution The bowhead is a cold-water species, living in the Arctic Ocean and surrounding waters. For management purposes, five stocks of bowhead whales are recognized [3]. [82], The bowhead whale has been hunted for blubber, meat, oil, bones, and baleen. [70] Also, bowheads in this stock were possibly once abundant in areas adjacent to the White Sea region, where few or no animals currently migrate, such as the Kola and Kanin Peninsula. [20] On average, female bowheads are larger than males. PCNA is also important in DNA repair. [59] Scientific research on this population was seldom done before 2009, when researchers studying belugas noticed concentrations of bowheads in the study area. This makes the bowhead whale one … During expeditions by a tour operator 'Arctic Kingdom', a large group of bowheads seemingly involved in courtship activities was discovered in very shallow bays south of Qikiqtarjuaq in 2012. Würsig, B. and C. Clark (1993). The Alaskan villages that participate in the bowhead subsistence harvest include Barrow, Point Hope, Point Lay, Wainwright, Nuiqsut, Kaktovik, Gambell, Savoonga, Kivalina, Wales, and Little Diomede. The bowhead whale is the only baleen whale to spend its entire life in the Arctic and subarctic waters. The whales tend to winter in areas with loose pack ice, such as northern Hudson Bay, Hudson Strait, central Davis Strait, southern Baffin … WWF played a key role in establishing the world’s first bowhead whale sanctuary, the Ninginganiq National Wildlife Area in Nunavut in 2009. Isabella Bay in Niginganiq National Wildlife Area is the first wildlife sanctuary in the world to be designed specially for bowhead whales. … [82] Bowheads seek the ice and shallow waters' safety when threatened by killer whales. The bowhead has suffered from severe over-exploitation that has seen its range shrink considerably since the 17th century. Studies in the 2000s finally provided clear evidence that the three living right whale species comprise a phylogenetic lineage, distinct from the bowhead, and that the bowhead and the right whales are rightly classified into two separate genera. Like the right whale, it swims slowly, and floats after death, making it ideal for whaling. [80] Floating skins and rubbing behaviours at sea bottom indicated possible moulting had taken place. [67], The most endangered but historically largest of all bowhead populations is the Svalbard/Spitsbergen population. Possibly, vagrants from this population occasionally reach into Asian nations such as off Japan or the Korean Peninsula (although this record might be of a right whale[63]). Whaling and climatic cooling during the Little Ice Age, from the 16th century to the 19th, is supposed to have reduced the whales' summer habitats, which explains the loss of genetic diversity. However, the numbers have been increasing in recent years.[46]. Northward migrating along western Foxe Basin to eastern side of the basin also occurs in spring. [82], Killer whales are also known predators. [38], Historical range could have been broader and more southern than that of currently regarded as bowheads had been abundant among Labrador and Newfoundland (Strait of Belle Isle), and northern Gulf of St. Lawrence at least until 16th and 17th centuries, although whether or not this was due to colder climate of those periods is unclear. [21], A 2013 discovery has clarified the function of the bowhead's large palatal retial organ. [50] Whaling grounds in 19th century covered from Marble Island to Roes Welcome Sound and to [44] These larger numbers correspond to prewhaling estimates, indicating the population has fully recovered. As recently as 1998, Dale Rice, in his comprehensive and otherwise authoritative classification, Marine Mammals of the World: Systematics and Distribution, listed just two species: B. glacialis (the right whales) and B. mysticetus (the bowheads).[11]. Bowheads are one of the longest living mammals on the planet. Today, the number of sightings elsewhereis very small,[71] but with increasing regularities[72] with whales having strong regional connections. [7], The bowhead was an early whaling target. They have the largest mouth of any … [30] Other bowhead whales were estimated to be between 135 and 172 years old. ASAMM surveys large areas of bowhead whale and killer whale summer and autumn habitat and offers consistent information on bowhead whale carcasses. [89], Bowheads were first taken along the pack ice in the northeastern Sea of Okhotsk, then in Tausk Bay and Northeast Gulf (Shelikhov Gulf). It is able to dive and remain submerged under water for up to an hour. [24] The bowhead whale is a filter feeder, and feeds by swimming forward with its mouth wide open. The bowhead whales found off Alaska spend the winter months in the southwestern Bering Sea. mostly shallow coastal water less than 200m deep amongst the sea ice [86], In the North Pacific, the first bowheads were taken off the eastern coast of Kamchatka by the Danish whaleship Neptun, Captain Thomas Sodring, in 1845. [82] Both stocks are rising, and the indigenous hunts seem to be self-sustaining. [50] Fewer whales also migrate to the west coast of Hudson Bay and Mansel and Ottawa Islands. Fun fact: These whales are … This organ becomes engorged with blood, causing the whale to open its mouth to allow cold seawater to flow over the organ, thus cooling the blood. [27], Sexual activity occurs between pairs and in boisterous groups of several males and one or two females. In Burns, J. J.; Montague, J. J.; and Cowles, C. J. Moore, S. E., and R. R. Reeves (1993). The Hudson Bay – Foxe Basin population is distinct from the Baffin Bay – Davis Strait group. This estimate is reinforced by the discovery of ivory and stone harpoon tips – not used since the 1800s – imbedded in whales harvested in recent years by Alaska Natives.17,18,19. [68] Occurring normally in Fram Strait,[69] Barents Sea and Severnaya Zemlya along Kara Sea[46] to Laptev Sea and East Siberian Sea regions, these whales were seen in entire coastal regions in European and Russian Arctic, even reaching to Icelandic and Scandinavian coasts and Jan Mayen in Greenland Sea, and west of Cape Farewell and western Greenland coasts. "Commercial Whaling in the North Pacific Sector". It is also known as Greenland Right Whale. These mutations enable bowhead whales to better repair DNA damage, allowing for greater resistance to cancer. [12] The right whales were thus confirmed to be in a separate genus, Eubalaena. mostly shallow coastal water less than 200m deep amongst the sea ice [88], Commercial whaling, the principal cause of the population decline, is over. The global population is assessed as of least concern.[3][8]. It is circumpolar and spends winter around the southern edge of the sea ice. Other common names of the species are the Greenland right whale or Arctic whale. It is best known for its long baleen plates, which are specialized feeding tools used in place of teeth, and its sharply bowed upper jaw, which gives the whale its common name. Bowhead hunting is limited to whaling crews who are: This bowhead subsistence hunting occurs during the northward spring migrations based from the ice and from small boats during the returning fall migrations. The whaling settlement Smeerenburg was founded on Spitzbergen in 1619. Bowhead hunting happens in fall too if it’s good weather and ice conditions are suitable for going out—late November when the ice is starting to come in. The team used a highly detailed dataset to model suitable habitat for western Arctic bowhead whales in the Beaufort Sea north of Alaska. [23] The Inuit have a word for this behavior to give historical context that this is not a new phenomenon. [83] There is no consensus on the number of deaths by killer whales. during the Pleistocene were far more southerly as fossils have been excavated from Italy and North Carolina, thus could have overlapped between those of Eubalaena based on those locations. Today, the bowhead whale occupies a monotypic genus, separate from the right whales, as proposed by the work of John Edward Gray in 1821. Top. The time spent under water in a single dive is usually limited to 9–18 minutes. Bowhead Whales live in the very cold Arctic and subarctic waters. The other path comes near land to the east of Pugughileq, follows the coast past Southwest Cape, but then turns offshore in a northwestward direction towards the coast of Chukotka…Few whales go past the east end of the island, although the presence of bowhead bones in archeological sites…suggests that at least some whales, at some time of the year, have traveled that way in the past.10 From “Traditional Knowledge of the Bowhead Whale (Balaena mysticetus) around St. Lawrence Island, Alaska”, Bowhead whales are the only large whales that spend most of their life in or near sea ice. [39] Distributions of Balaena spp. Bowheads have the largest mouth of any animal [5] representing almost one-third of the length of the body, the longest baleen plates with a maximum length of 4 m (13.1 ft) [6] and may be the longest-lived mammals, with the ability to reach an age of more than 200 years. The tissue is histologically similar to that of the corpus cavernosum of the mammalian penis. The Alaska Eskimo Whaling Commission co-manages the bowhead subsistence harvest with the National Oceanic and Atmospheric Administration. [31] According to researchers at CSIRO, Australia's national science agency, the genome sequence revealed bowhead whales' maximum lifespan to be 268 years.[32]. They’re considered one of the largest whale species in the world. Bowhead whales are slow swimmers and usually travel alone or in sma… [60][61] Several companies provide whale-watching services, which are mostly land-based. Moulting behaviours had never or seldom been documented for this species before. The summer extent of the Eastern Canada−West Greenland bowhead whales ranges from Western Baffin Bay and the Canadian High Arctic to Northern Foxe Basin and Northwestern Hudson Bay. [90], Some Alaska Natives continue by tradition to hunt bowhead and beluga whales on a subsistence level, with low annual bowhead total quotas set by the International Whaling Commission in conjunction with individual village limits set by the Alaska Eskimo Whaling Commission.[91]. The summer extent of the Eastern Canada-West Greenland bowhead whales ranges from Western Baffin Bay and the Canadian High Arctic to Northern Foxe Basin and Northwestern Hudson Bay. These data suggest that the Western Arctic bowhead stock may be at or near its precommercial whaling level. The group migrates northward in the spring, following openings in the ice, into the Chukchi and Beaufort seas. Depending on the area and environment the whale is in some beluga whales will make seasonal migration trips while others will only travel within a small localized area. Biology. [82] Global warming is increasing the frequency that killer whales are observed in the far north. [43] The annual subsistence harvest of the Western Arctic stock has ranged from 14 to 72, amounting to an estimated 0.1-0.5% of the population. [28] In May 2007, a 15 m (49 ft) specimen caught off the Alaskan coast was discovered with the 3.5 in (89 mm) head of an explosive harpoon of a model manufactured between 1879 and 1885, so the whale was probably harpooned sometime between those years, and its age at the time of death was estimated at between 115 and 130 years. Habitat. The whale is mainly blue-black in colour, with cream-colour blotches on its lower jaw, white blotches on its belly, and a pale grey area on its tail. The first whales begin their spring journey past the island about a month earlier than they have historically and they are gone from the island on their way north about a month earlier. They break through ice over 20-cm thick with the crown of the head to breathe, and can navigate and communicate under extensive ice fields using their sophisticated acoustic sense. Bowhead whales were massively hunted in the past because of their meat and oil. The longest reliably measured were a male of 16.2 m (53 ft) and a female of 18 m (59 ft), both landed in Alaska. "Foods and Feeding Ecology". Intense calls for communication and navigation are produced especially during migration season. "Anatomy & Physiology".

(A) Bowhead whale habitat selection surfaces for sea ice concentration as killer whales move closer. First documented report of the species in Japanese waters was of a strayed infant (7 m [23 ft]) caught in Osaka Bay on 23 June 1969,[64] and the first living sighting was of a 10 m (33 ft) juvenile around Shiretoko Peninsula (the southernmost of ice floe range in the Northern Hemisphere) on 21 to 23 June 2015. LIFESPAN. Carl Linnaeus named this species in the 10th edition of his Systema Naturae (1758). It lives for over a hundred years, produces beautiful songs, and can break through sea ice a foot deep. In Burns, J. J.; Montague, J. J.; and Cowles, C. J. Haldiman, J. T. and R. J. Tarpley (1993). In Burns, J. J.; Montague, J. J.; and Cowles, C. J. 2007. Other common names for this animal are the Greenland Right Whale … Bowheads originally crossed ice-covered inlets and straits to exchange genes between Atlantic and Pacific populations. "Stock Sizes Prior to Commercial Whaling". waters from eastern Greenland and Spitsbergen to eastern Siberia Bowhead whales are now hunted on a subsistence level by native peoples of North America. This group migrates north in the spring, following the openings it finds in the ice, to the Beaufort and Chukchi seas. Soon, ships expanded to the west, catching them around Iony Island and then around the Shantar Islands. [74] The waters around the marine mammal sanctuary[75] of Franz Josef Land is possibly functioning as the most important habitat for this population.[76][77]. In 2015, scientists from the US and UK were able to successfully map the whale's genome. However, recent evidence suggests that the Hudson Bay and Foxe Basin stock and the Baffin Bay and Davis Strait stock should be considered one stock based on genetics and movements of tagged whales. According to whaling captain William Scoresby Jr., the longest bowhead he measured was 17.7 m (58 ft) long, while the longest measurement he had ever heard of was of a 20.4 m (67 ft) whale caught at Godhavn, Greenland, in early 1813. Ecological Variation in the Western Beaufort Sea. Two types of ENM techniques will be used, boosted regression trees and maximum entropy density estimation, to produce seasonal and long range (5-10yr) estimates of bowhead whale … Flippers are small and rounded, and the bowhead … [36] The Alaskan population spends the winter months in the southwestern Bering Sea. Eventually, it was recognized that bowheads and right whales were different, but there was still no strong consensus as to whether they shared a single genus or two. [50] Bowhead ranges within Hudson Bay are usually considered not to cover southern parts,[49][55] but at least some whales migrate into further south such as at Sanikiluaq[citation needed] and Churchill river mouth. CMS Parties strive towards strictly protecting these animals, conserving or restoring the places where they live, mitigating obstacles to migration, and controlling other factors that might endanger them. The IUCN Red List data are:[84], The Alaska Department of Fish and Game and the USA government list the bowhead whale as federally endangered. [94], The bowhead whale is listed in Appendix I[95] of the Convention on the Conservation of Migratory Species of Wild Animals (CMS), as this species has been categorized as being in danger of extinction throughout all or a significant proportion of its range. Contact: eloka@nsidc.org, Elders (after group discussion in Yupik)—Gambell, From “Traditional Knowledge of the Bowhead Whale (Balaena mysticetus) around St. Lawrence Island, Alaska”, Endnotes, References, Acknowledgements, Appendix. They feed predominately on tiny crustaceans, including copepods, amphipods and krill that are filtered through baleen plates in the mouth of the whale.16, Some bowhead whales are thought to live 150-200 years. [16] Unlike most cetaceans, the bowhead does not have a dorsal fin - an adaptation for spending much time under sea-surface ice.[17]. The whales tend to winter in areas with loose pack ice, such as northern Hudson Bay, Hudson Strait, central Davis Strait, southern Baffin … Spring migration arrows were previously published by Noongwook et al. [25] While foraging, bowheads are solitary or occur in groups of two to 10 or more. Authorities have repeatedly recategorized the three populations of right whale plus the bowhead whale, as one, two, three or four species, either in a single genus or in two separate genera. In Burns, J. J.; Montague, J. J.; and Cowles, C. J. Koski, William R., Rolph A. Davis, Gary W. Miller, and David E. Withrow (1993). [23] When fleeing from danger, it can travel at a speed of 10 km/h (6.2 mph) [2.78 m/s (9.1 ft/s)]. Adu… However, if the killer whale … Bowhead whales are large and stocky animals, with a rounded body and a large head that comprises about a third of the total length. During physical exertion, the whale must cool itself to prevent hyperthermia (and ultimately brain damage). [41], The Western Arctic bowhead population, also known as the Bering-Chukchi-Beaufort population, has recovered since the commercial harvest of this stock ceased in the early 1900s. The bowhead whale size is impressive, to say the least! To feed, water is filtered through the fine hairs of keratin of the baleen plates, trapping the prey inside near the tongue where it is then swallowed. By 1849, 50 ships were hunting bowheads in each area; in the Bering Strait, 500 whales were killed that year, and that number jumped to more than 2000 in 1850. [65] Fossils have been excavated on Hokkaido,[66] but it is unclear whether or not northern coasts of Japan once had been included in seasonal or occasional migration ranges. FEATURED The extensive repertoire of bowhead … The bowhead whale (Balaena mysticetus) is a species of baleen whale belonging to the family Balaenidae and the only living representative of the genus Balaena. [23] From 2010 through to 2014, near Greenland, 184 distinct songs were recorded from a population of around 300 animals. This conclusion was derived from analyzing maternal lineage using mitochondrial DNA. To survive in the cold water immediately after birth, calves are born with a thick layer of blubber. [24], The head of the bowhead whale comprises a third of its body length, creating an enormous feeding apparatus. Model output from the time and location of bowhead whale sightings, from aerial and acoustic surveys, will be used to train an environmental niche model (ENM) that characterizes bowhead whale habitat. Unlike other whale species that are known to migrate to warmer temperatures during mating season the bowhead whale remains in the arctic/sub arctic waters all year round.Although the bowhead only travels in arctic waters it can be found migrating to various locations in the upper northern hemisphere such as the Bering sea, Beaufort sea and Chukchi sea.In order to manage living in cold waters throughout t… [14], The bowhead whale has a large, robust, dark-coloured body and a white chin/lower jaw. This predominantly Arctic species is associated with ice floes. [20], Bowhead whales are considered to be the longest-living mammals, living for over 200 years. During breeding season, bowheads make long, complex, variable songs for mating calls. (2012). [16], Bowhead whales are highly vocal[26] and use low frequency (<1000 Hz) sounds to communicate while travelling, feeding, and socialising. [73] Whales have also started approaching townships and inhabited areas such as around Longyearbyen. In Burns, J. J.; Montague, J. J.; and Cowles, C. J. Lowry, L. F. (1993).

"Reproduction". In Burns, J. J.; Montague, J. J.; and Cowles, C. J. Bockstoce, J. R., and J. J. Burns (1993). "Commercial Whaling in the North Atlantic Sector". In the cold water of the Arctic, an animal with a huge, bow-shaped mouth feeds and sings. The Bowhead Whale is a member of the mammal family and the scientific term for them is Balaena mysticetus. Bowhead … An estimated 18,000 bowheads were killed in the Sea of Okhotsk during 1847–1867, 80% in the first decade. Found in both northern Atlantic and Pacific waters, the species has evolved thick skin and blubber for insulation and a source of energy reserves, an enormous, strong and bowed head that can break through ice up to 1 m thick, and an ability to stay under water for over an hour at a time to swim beneath the ice 1,2. Philo, L. M., E. B. Shotts, and J. C. George (1993). The Physical Oceanographic Setting of Bowhead Whale Habitat 26. Bowhead whales are comparable in size to the three species of right whales. Bowhead whales are the only large whales that spend most of their life in or near sea ice. Its population was severely reduced before a 1966 moratorium was passed to protect the species. Even though hunting of bowhead whales is prohibited by law today, remaining bowhead … Beluga Whale – Beluga whales are generally found swimming in shallow coastal waters in and around Arctic waters. [81], In 1978 the International Whaling Commission (IWC) introduced a hunting strike quota for the Bering-Chukchi-Beaufort Sea (BCB) bowhead. [88] An estimated 18,600 bowheads were killed in the Bering Strait region between 1848 and 1914, with 60% of the total being reached within the first two decades. They later spread to the western Beaufort Sea (1854) and the Mackenzie River delta (1889). 5. "Behavior". The relationship is shown in the cladogram below: The earlier fossil record shows no related cetacean after Morenocetus, found in a South American deposit dating back 23 million years. [33] Although the bowhead whale has thousands of times more cells than other mammals, it has a much higher resistance to cancer and aging.
