흰돌고래/Beluga Whale/白い鯨//シロイルカ
최대몸길이 4.5m, 몸무게 1.5t이다. 영어명은 벨루가(Beluga 혹은 Belukha) 또는 화이트 훼일(White Whale)이다. 출생 직후의 몸길이는 1.5m이며, 암컷은 5∼6세, 수컷은 8∼9세에 성숙한다.
목을 90˚가까이 좌우로 구부릴 수 있을 만큼 유연하며 피부가 매우 부드럽다. 일각과에 속하지만 이빨로 된 뿔은 없다. 이빨은 위턱에 8∼11개, 아래턱에 8∼9개가 불규칙하게 나 있으며, 때로는 휘어져 있기도 하다. 등면 중앙에 피부가 약간 솟아 있으며, 등지느러미는 없다.
사람에게 잘 길들여지며, 잠수한 채로 2∼3㎞까지 이동할 수 있다. 물 속에서 카나리아와 비슷한 울음소리를 낸다. 주로 오징어·연어·청어·갑각류 등을 먹는다. 보통 5∼10마리가 무리지어 회유하나, 번식기에는 100∼200마리의 무리를 이룬다. 번식기는 봄이고, 임신기간은 약 14개월이며, 2∼3년에 한배에 1마리를 출산한다. 수유기간은 약 2년이다.
일생 동안 한 집단 안에서 생활한다. 북극에 살고 있는 사람들에게 기름과 가죽을 제공해 주는 귀중한 동물이다. 북극해와 베링해, 캐나다 북부 해역, 그린란드 주변을 회유(回游)한다.
The beluga whale (/bɪˈluːɡə/) (Delphinapterus leucas) is an Arctic and sub-Arctic cetacean. It is one of two members of the family Monodontidae, along with the narwhal, and the only member of the genus Delphinapterus. It is also known as the white whale, as it is the only cetacean of this colour; the sea canary, due to its high-pitched calls; and the melonhead, though that more commonly refers to the melon-headed whale, which is an oceanic dolphin.
The beluga is adapted to life in the Arctic, so it has anatomical and physiological characteristics that differentiate it from other cetaceans. Amongst these are its all-white colour and the absence of a dorsal fin, which allows it to swim under ice with ease.[3] It possesses a distinctive protuberance at the front of its head which houses an echolocation organ called the melon, which in this species is large and deformable. The beluga's body size is between that of a dolphin and a true whale, with males growing up to 5.5 m (18 ft) long and weighing up to 1,600 kg (3,530 lb). This whale has a stocky body. Like many cetaceans, a large percentage of its weight is blubber (subcutaneous fat). Its sense of hearing is highly developed and its echolocation allows it to move about and find breathing holes under sheet ice.
Belugas are gregarious and form groups of 10 animals on average, although during the summer, they can gather in the hundreds or even thousands in estuaries and shallow coastal areas. They are slow swimmers, but can dive to 700 m (2,300 ft) below the surface. They are opportunistic feeders and their diets vary according to their locations and the season. The majority of belugas live in the Arctic Ocean and the seas and coasts around North America, Russia and Greenland; their worldwide population is thought to number around 150,000. They are migratory and the majority of groups spend the winter around the Arctic ice cap; when the sea ice melts in summer, they move to warmer river estuaries and coastal areas. Some populations are sedentary and do not migrate over great distances during the year.
The native peoples of North America and Russia have hunted belugas for many centuries. They were also hunted by non-natives during the 19th century and part of the 20th century. Hunting of belugas is not controlled by the International Whaling Commission, and each country has developed its own regulations in different years. Currently some Inuit in Canada and Greenland, Alaska Native groups and Russians are allowed to hunt belugas to consume and sell; aboriginal whaling is excluded from the International Whaling Commission 1986 moratorium on hunting. The numbers have dropped substantially in Russia and Greenland, but not in Alaska and Canada. Other threats include natural predators (polar bears and killer whales), contamination of rivers (as with Polychlorinated biphenyl (PCBs) which bioaccumulate up the food chain) and infectious diseases. The beluga was placed on the International Union for Conservation of Nature's Red List in 2008 as being "near threatened"; the subpopulation from the Cook Inlet in Alaska, however, is considered critically endangered and is under the protection of the United States' Endangered Species Act. Of seven Canadian beluga populations, those inhabiting eastern Hudson Bay, Ungava Bay and the St. Lawrence River are listed as endangered.
Belugas are one of the most commonly kept cetaceans in captivity and are housed in aquariums, dolphinariums and wildlife parks in North America, Europe and Asia. They are popular with the public due to their colour and expression.
