It is unclear whether the two sightings from the same area on June 25 and July 19, 2019 belong to the same individual (see above). No coastal or other wintering ground has been found for North Pacific right whales. The IUCN Red List data are:, The Alaska Department of Fish and Game and the USA government list the bowhead whale as federally endangered. In winter, the whales' distribution is particularly mysterious. Afterward, General Douglas MacArthur, head of Allied occupation forces, encouraged the Japanese to resume whaling to feed their hungry population. Like the right whale, it swims slowly, and floats after death, making it ideal for whaling. Gunshot calls appear to be made by males and may be associated with some aspect of mating. The tail fluke is broad (up to 40% of body length). , During the 1960s, the IWC did not place observers on whaling ships. Japan then joined the International Whaling Commission which barred the hunting of right whales. 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.It is the only baleen whale endemic to the Arctic and subarctic waters. The callosities appear white due to large colonies of cyamids (whale lice). The southern right whale has made Hermanus, South Africa one of the world centers for whale watching. , Additionally, there have been two sightings of individual right whales off British Columbia in 2013. The Plan also contains proposed conservation measures, which mainly consist of various research proposals including passive acoustic monitoring, satellite tagging, and review of historic whaling logbooks.  Last records off west coast were in 1998 off Cape San Martin and Monterey.  Ryukyu Islands had been suggested as a wintering ground for the western population, but little evidence supports this. Despite intensive searching, they were unable to spot the animals visually. , Bowheads were first taken along the pack ice in the northeastern Sea of Okhotsk, then in Tausk Bay and Northeast Gulf (Shelikhov Gulf). The densest concentrations occurred along both coasts of Kamchatka and in the Gulf of Alaska. Omura, H., S. Ohsumi, K. N. Nemoto, K. Nasu, and T. Kasuya. Isabella Bay in Niginganiq National Wildlife Area is the first wildlife sanctuary in the world to be designed specially for bowhead whales. The next most common call has been labeled the "downcall" and this is also fairly stereotypic. In winter, the ice-loving Bowhead moves south into the Bering Sea, but the right whales have migrated further south of the Aleutian Islands into the North Pacific. Modern sightings in the East and South China Seas, or Yellow and Bohai Seas are very rare, and the number of records is small. In the west, most recent sightings of right whales occur along the Kamchatka Peninsula, in the Kurile Islands, in the Sea of Okhotsk, and the Commander Islands, along the coasts of Japan. For 10 North Pacific right whales taken in the 1960s, their girth in front of the flippers was 0.73 of the total length of the whale.  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). There is no evidence that right whales' sounds are used for echolocation as is seen in dolphins and toothed whales.

A few Native American tribes hunted in the North Pacific.  The functional purpose of the callosities has not been determined. Pelagic whalers in the 19th century hunted large numbers of right whales along the coasts of Kamchatka and in the Sea of Okhotsk. Was the population in the Sea of Okhotsk a third population distinct from the whales found in the Pacific east of Kamchatka? However, they are highly acrobatic and frequently breach (jump clear of the sea surface), tail-slap and lobtail.. 2015). Belonovich O. In 1611, the first whaling expedition sailed to Spitsbergen. , Like right whales in other oceans, North Pacific right whales feed primarily on copepods, mainly the species Calanus marshallae. PeerJ 5:e3464. These whales belong to Davis Strait stock. Aside from the strongly-build tails and massive heads equipped with callosities, the sheer size of this animal is its best defense, making young calves are the most vulnerable to orca and shark attacks. He also spoke of one, caught near Spitsbergen around 1800, that was allegedly nearly 21.3 m (70 ft) long. The later "factory ships" that processed carcasses while at sea further transformed pelagic whaling. Right whales have rotund bodies with arching rostrums, V-shaped blowholes and dark gray or black skin.  There have been claims that pectoral fins of pacific right whale are larger in portion than the other right whales and more pointed, and there may exist shape differences of tail by individuals or sex. He also documented an additional 126 right whales killed in the Sea of Okhotsk between 1963 and 1968 and another 10 in the Kuril Islands in 1971. On August 10, 2004, a group of two were seen in the Bering Sea. CS1 maint: BOT: original-url status unknown (.  The absence of calves from historic California stranding data suggests that this area was never an important calving or wintering ground. These areas support extensive and multi-species commercial fisheries for pollock, flatfish, cod, various crabs and other resources (but not salmon). In 2010, a team led by National Marine Mammal Laboratory ecologist Brendan Kelly counted 34 possible hybridizations between distinct populations or species of Arctic marine mammals, many of which are endangered or threatened. , Killer whales are also known predators.  Since hunting of the southern right whale ceased, stocks are estimated to have grown by 7% a year.
