Features of the bowhead whale brain include a blunted temporal lobe and a gyrification index that is less than most cetaceans. Based on the recovery of stone harpoon tips in their blubber, and from analysis of eye tissue, scientists believe that the life-span of bowhead whales can be over 200 years. The Alaskan population spends the winter months in the southwestern Bering Sea.  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. Mating can take place throughout the year, but there is a peak in mating activity during late winter and spring. In Burns, J. J.; Montague, J. J.; and Cowles, C. J. Moore, S. E., and R. R. Reeves (1993). These animals exhibit slow growth and high survival.  Although the bowhead whale has thousands of times more cells than other mammals, it has a much higher resistance to cancer and aging. The Alaska Eskimo Whaling Commission co-manages the bowhead subsistence harvest with the National Oceanic and Atmospheric Administration.  The whale's genome may also reveal physiological adaptations such as having low metabolic rates compared to other mammals. , Sexual activity occurs between pairs and in boisterous groups of several males and one or two females. 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, 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. 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. Find out more, The Telegraph values your comments but kindly requests all posts are on topic, constructive and respectful. In Burns, J. J.; Montague, J. J.; and Cowles, C. J. Lowry, L. F. (1993). 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. 2. Bowheads have the largest mouth of any animal  representing almost one-third of the length of the body, the longest baleen plates with a maximum length of 4 m (13.1 ft)  and may be the longest-lived mammals, with the ability to reach an age of more than 200 years. During physical exertion, the whale must cool itself to prevent hyperthermia (and ultimately brain damage). This area is an important habitat for whales that were observed to be relatively active and to interact with humans positively, or to rest on sea floors. In the Western Arctic, they mainly caught them in the Anadyr Gulf, the Bering Strait, and around St. Lawrence Island.  Bowhead ranges within Hudson Bay are usually considered not to cover southern parts, but at least some whales migrate into further south such as at Sanikiluaq and Churchill river mouth. , The bowhead was an early whaling target.  Larger portions of the bay are used for summering, while wintering is on smaller scale where some animals winter in Hudson Strait most notably north of Igloolik Island and northeastern Hudson Bay. This group migrates north in the spring, following the openings it finds in the ice, to the Beaufort and Chukchi seas.  The population of bowheads in West Greenland and Canada is estimated to be 6,000 and rising, and hunts in this are minimal (<0.001 percent). This conclusion was derived from analyzing maternal lineage using mitochondrial DNA. He also spoke of one, caught near Spitsbergen around 1800, that was allegedly nearly 21.3 m (70 ft) long. The Hudson Bay – Foxe Basin population is distinct from the Baffin Bay – Davis Strait group. "Reproduction".  Through comparative analysis, two alleles that could be responsible for the whale's longevity were identified. In fact, he’s only middle-aged at that point in his astoundingly long life. Native Alaskans and Canadian Inuit are allowed a limited subsistence hunt for bowhead whales … After analysing the genetic code of 252 vertebrates, Australian scientists found 42 genes which predict length of life, and were able to tell that the average bowhead will live for 268 years, some 57 years longer than the oldest known whale. It takes 13 to 14 months after mating for the calf to be born. It is the only baleen whale endemic to the Arctic and subarctic waters. A 2011 study estimated that the Western Arctic population was 16,892 (95% CI: 15,074-18,928), more than triple the population estimate in 1978. The bowhead is the only whale of the baleens to spend its whole life in arctic and sub-arctic seas. , Bowheads were first taken along the pack ice in the northeastern Sea of Okhotsk, then in Tausk Bay and Northeast Gulf (Shelikhov Gulf). These two specific gene mutations linked to the bowhead whale's ability to live longer are the ERCC1 gene and the proliferating cell nuclear antigen (PCNA) gene. Bowhead whales feed on planktonic organisms including copepods, amphipods, euphausiids, and various other crustaceans. Some bowhead whales have been discovered with harpoons dating from the 1880s, proving they can survive for huge periods but their true lifespan has remained a mystery. Researchers are using its genetic blueprint to probe how it is that this species can live longer than 200 years. A once-rare event, killer whales are now seen more frequently. While many ocean lovers can easily identify the iconic sperm whale, the charismatic humpback and the wily orca, not all are familiar with the bowhead. These whales are slow swimmers, normally travelling around 2–5 km/h (1.2–3.1 mph) [0.55–1.39 m/s (1.8–4.6 ft/s)]. & Zerbini, A.N. Some populations are faring better as a result. WWF welcomed the creation a nature sanctuary in the region. , Bowhead whales are highly vocal and use low frequency (<1000 Hz) sounds to communicate while travelling, feeding, and socialising. However, discoveries of antique ivory spear points in living whales in 1993, 1995 and 1999 have triggered further research based on structures in the whales eye, leading to the reliable conclusion that at least some individuals have lived to be 150 – 200 years old (another report has said a female at the age of 90 was allegedly still reproductive). “The lifespan clock also creates a new opportunity to study the biology of extinct species, where ancient DNA methods can provide genome assemblies,” added Dr Mayne. 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. In May 2007, a 15 m (49 ft) specimen caught off the Alaskancoast 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. Generally this is when they are from 10 to 15 years of age. The male whale’s mating songs are at their peak in March. Bowhead whales have the thickest blubber of any whale species at 17 to 19 inches (43 to 48 cm) thick. , 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 lifespan of a Bowhead whale was once thought to be 60 to 70 years, similar to other whales. 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).. The population was severely reduced before a 1966 moratorium was passed to protect the species. We urge you to turn off your ad blocker for The Telegraph website so that you can continue to access our quality content in the future.  Other bowhead whales were estimated to be between 135 and 172 years old. The females will give birth to one calf every 3 or 4 years. Northward migrating along western Foxe Basin to eastern side of the basin also occurs in spring. A bowhead whale has a lifespan of up to 100 years, although a few have been estimated to live up to 200 years. Because of their possible life span, female bowhead whales are believe… Thus, bowheads in the Sea of Okhotsk were once called "forgotten whales" by researchers. , Bowhead whales are not social animals, typically travelling alone or in small pods of up to six. 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. 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). Soon, ships expanded to the west, catching them around Iony Island and then around the Shantar Islands. According to Russian scientists, this total population likely does not exceed 400 animals. Bowheads are named after their characteristic massive triangular skull, which is used to break through Arctic ice. , The most endangered but historically largest of all bowhead populations is the Svalbard/Spitsbergen population. They Its baleen is the longest of that of any whale, at 3 m (9.8 ft), and is used to strain tiny prey from the water. For some species, like the Greenland shark which may live more than 500 years, scientists are forced to use carbon dating, but the inaccuracy of the process means that estimates can be out by more than 100 years. 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. Growth may be faster in females than in males, and … A bowhead whale surfaces from a dive in the chilly waters of Lancaster Sound, Canada.  Cow – calf pairs and juveniles up to 13.5 m (44 ft) in length consist of majority of summering aggregation in northern Foxe Basin, while matured males and noncalving females may use the northwestern part of Hudson Bay.  The diet consists of mostly zooplankton, which includes copepods, amphipods, and many other crustaceans. "Distribution and Movement". During periods of feeding, the average swim speed is increased to 1.1–2.5 m/s (3.6–8.2 ft/s) [3.96–9 km/h (2.46–5.59 mph)]. The book also discusses the biological and physical aspects of the Arctic ecosystem in which these whales live, with careful attention paid to the dramatic changes taking place. However, if climate change substantially shrinks sea ice, these whales could be threatened by increased shipping traffic. Long-lived animals are notoriously difficult to track from birth to death, because researchers do not live long enough to follow them throughout their lives. 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. 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. You need to be a subscriber to join the conversation. In 1611, the first whaling expedition sailed to Spitsbergen. Bowhead Whale. They are able to mate when they reach a length of 35 to 40 feet. LOKE FILM AND ADAM SCHMEDES/CELL REPORTS 2015  The Inuit have a word for this behavior to give historical context that this is not a new phenomenon. This also prevents buckling or breakage of the plates from the pressure of the water passing through them as the whale advances.  Spurred by this discovery, scientists measured the ages of other bowhead whales; one specimen was estimated to be 211 years old. 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. The tissue is histologically similar to that of the corpus cavernosum of the mammalian penis. They consume about two tons of food a day. The global population is assessed as of least concern.. Current status of population structure of this stock is unclear, whether they are remnant of the historic Svalbard group, recolonized individuals from other stocks, or if a mixing of these two or more stocks had taken place.  Fewer whales also migrate to the west coast of Hudson Bay and Mansel and Ottawa Islands. , Commercial whaling, the principal cause of the population decline, is over. 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. An estimated 18,000 bowheads were killed in the Sea of Okhotsk during 1847–1867, 80% in the first decade. 1. 3. , 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. Bowheads are not ones to be rushed and don’t really do anything particularly quickly.  From 2010 through to 2014, near Greenland, 184 distinct songs were recorded from a population of around 300 animals. 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. “It is rarely possible to follow long-lived species from birth to death as they would normally out live a generation of researchers. , Killer whales are also known predators. , The bowhead whale has a large, robust, dark-coloured body and a white chin/lower jaw. What allows Bowhead whales to live for over two centuries is their low body temperature and environment – the lower a mammal’s body temperature, the longer it … Bowhead whales are now hunted on a subsistence level by native peoples of North America. 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. They later spread to the western Beaufort Sea (1854) and the Mackenzie River delta (1889). Nefedova T., Gavrilo M., Gorshkov S., 2013. Distribution patterns of whales in this regions are largely affected by presences of killer whales, and bowheads can disappear from normal ranges due to recent changes in killer whales' occurrences within the bay possibly because of changes in movements of ice floes by climate change. The gestation period is 13–14 months with females producing a calf once every three to four years.  It also possesses a strongly bowed lower jaw and a narrow upper jaw. Of the five stocks of bowhead populations, three are listed as "endangered", one as "vulnerable", and one as "lower risk, conservation dependent" according to the IUCN Red List. The Alaskan population winter in the southwestern Bering Sea. “Using our lifespan estimator and the bowhead whale genome, we estimated the maximum longevity of the bowhead whale to be 268 years.  Global warming is increasing the frequency that killer whales are observed in the far north.  Distributions of Balaena spp.  Occurring normally in Fram Strait, Barents Sea and Severnaya Zemlya along Kara Sea 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. It is estimated that calves are probably born every three or four years after a gestation period of 13-14 months. , 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. Bowhead whales need to eat about 220,000 pounds (100 tons) of food a year. Can its genes tell us why? In Burns, J. J.; Montague, J. J.; and Cowles, C. J.  The Alaskan population spends the winter months in the southwestern Bering Sea. But they’re not.  Bowheads are not thought to be deep divers, but they can reach a depth down to 500 ft (150 m). 21 Sample size Medium Data quality Acceptable Observations. Based on the recovery of stone harpoon tips from harvested bowheads, it is evident that bowhead whales live well over 100 years. 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. To learn more about the population, these mammals have been regularly observed near the Shantar Islands, very close to the shore, such as at Ongachan Bay. Inuit hunters have reported bowheads surfacing through 60 cm (24 in) of ice. Isabella Bay in Niginganiq National Wildlife Area is the first wildlife sanctuary in the world to be designed specially for bowhead whales. 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. , 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. Würsig, B. and C. Clark (1993). Mating generally will occur in March. These data suggest that the Western Arctic bowhead stock may be at or near its precommercial whaling level. "Behavior". , Congregation within Foxe Basin occurs in a well-defined area at 3,700 km (2,300 mi) north of Igloolik Island to Fury and Hecla Strait and Jens Munk Island and Gifford Fiord, and into Gulf of Boothia and Prince Regent Inlet. Bowhead whales grow up to 60 feet (18.3 m) and 200,000 pounds (91 tons).  About 2 short tons (1.8 long tons; 1.8 t) of food are consumed each day.  In 1847, the first bowheads were caught in the Sea of Okhotsk, and the following year, Captain Thomas Welcome Roys, in the bark Superior, of Sag Harbor, caught the first bowheads in the Bering Strait region. "Morbidity and Mortality." Within 30 minutes of birth, bowhead calves are able to swim on their own.  Scientific research on this population was seldom done before 2009, when researchers studying belugas noticed concentrations of bowheads in the study area. ERCC1 is linked to DNA repair and increased cancer resistance. Likewise the Woolly Mammoth would have lived to 60, while the passenger pigeon which died out in 1914 had a lifespan of 28 years. Like some other members of the order Cetacea, bowhead whales slap their … They can be up to 13 feet long, very large compared to other animal species. , The head of the bowhead whale comprises a third of its body length, creating an enormous feeding apparatus. Bowhead whales are one of the least encephalized mammals, possessing a small brain relative to their body size (e.g., a 3 kg brain in a 30,000 kg body). "Balaena mysticetus Linnaeus 1758 (bowhead whale)", 10.2305/IUCN.UK.2012.RLTS.T2467A17879018.en, "Whale bones found in highway were not from mystery whale", "Bowhead whales lost genetic diversity, study shows", "Natural History and Conservation of the Greenland Whale, or Bowhead, in the Northeast Atlantic", "Behaviour and Kinematics of Continuous Ram Filtration in Bowhead Whales (, "Bowhead Whale : Baleen Whales : Voices in the Sea", "Comparative oncology: what dogs and other species can teach us about humans with cancer", "Can Marine Biology Help Us Live Forever? Bowheads originally crossed ice-covered inlets and straits to exchange genes between Atlantic and Pacific populations. Between 1854 and 1857, the fleet shifted to the Sea of Okhotsk, where 100–160 ships cruised annually. However, moultings have not been recorded in this area due to environmental factors. Discover How Long Bowhead whale Lives. However, it can occur any time from March through August.  According to researchers at CSIRO, Australia's national science agency, the genome sequence revealed bowhead whales' maximum lifespan to be 268 years.. OUR DATA: We use the most recent data from these primary sources: AnAge, UMICH, Max Planck, PanTHERIA, Arkive, UKC, AKC. This discovery showed the longevity of the bowhead whale is much greater than originally thought. 4.  Changes in the gene UCP1, a gene involved in thermoregulation, can explain differences in the metabolic rates in cells.  The whale's range varies depending on climate changes and on the forming/melting of ice. Basin, and north of Igloolik in summer, and satellite tracking indicates that some portions of the group within the bay do not venture further south than such as Whale Cove and areas south of Coasts and Mansel Islands. The Bowhead Whale: Balaena mysticetus: Biology and Human Interactions covers bowhead biology from their anatomy and behavior, to conservation, distribution, ecology and evolution. The group migrates northward in the spring, following openings in the ice, into the Chukchi and Beaufort seas.  Before commercial whaling, they were estimated to number 50,000. “It estimated the maximum lifespan of the Pinta Island tortoise to be 120 years old. In 2015, scientists from the US and UK were able to successfully map the whale's genome. Bowhead whales have a life expectancy of at least 40 years, but perhaps longer.  Several companies provide whale-watching services, which are mostly land-based. Philo, L. M., E. B. Shotts, and J. C. George (1993). These whales belong to Davis Strait stock.  Original population size of this local group is unclear, but possibly about 500 to 600 whales annually summered in the northwestern part of the bay in 1860s. It provides protective padding and buoyancy as well as insulation. In Burns, J. J.; Montague, J. J.; and Cowles, C. J. Haldiman, J. T. and R. J. Tarpley (1993). To survive in the cold water immediately after birth, calves are born with a thick layer of blubber. 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. A greater number of cells present in an organism was once believed to result in greater chances of mutations that cause age-related diseases and cancer.  Whales have also started approaching townships and inhabited areas such as around Longyearbyen.  Lactation typically lasts about a year. Today, the bowhead whale occupies a monotypic genus, separate from the right whales, as proposed by the work of John Edward Gray in 1821. Historically, age determination in bowhead whales has been difficult, and life history parameters are better known in terms of body length than age. However, the numbers have been increasing in recent years.. While the global population is thought to be secure, thus assigned "least concern" status, some populations are listed by the National Marine Fisheries Service as "endangered" under the auspices of the United States' Endangered Species Act. Writing in the journal Scientific Reports, Dr Benjamin Mayne, a molecular biologist at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Canberra, said: “Bowhead whales are thought to be the longest living mammal, with one individual estimated as 211 years old. The team also applied their lifespan clock to extinct species and discovered that the life expectancy of Neanderthals was 37.8. The blubber of a bowhead whale may be as thick as 1.6 feet.  This study puts the yearly growth rate at 3.7% (95% CI = 2.8-4.7%) from 1978 to 2011. "Anatomy & Physiology". It can also be used as a source of energy. About 1,200 were off West Greenland in 2006, while the Svalbard population may only number in the tens. Surviving for at least 200 years, the bowhead whale is the longest living mammal on Earth but zoologists have struggled to discover its true life expectancy. Bowheads have thousands of times the amount of cells we have, and should be more susceptible to cellular disorders such as cancer.
