Individual captive animals have been recorded at depths between 400 and 647 m below sea level, [74] while animals in the wild have been recorded as diving to a depth of more than 700 m, with the greatest recorded depth being over 900 m. [75] A dive normally lasts 3 to 5 minutes, but can last up to over 20 minutes.
Earth's ocean. The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. [1] It spans an area of approximately 14,060,000 km 2 (5,430,000 sq mi) and is the coldest of the world's oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic ...

Clione limacina, known as the naked sea butterfly, sea angel, and common clione, is a sea angel (pelagic sea slug) found from the surface to greater than 500 m (1,600 ft) depth. [2][3] It lives in the Arctic Ocean and cold regions of the North Atlantic Ocean. It was first described by Friderich Martens in 1676 and became the first gymnosomatous ...
The bearded seal (Erignathus barbatus), also called the square flipper seal, is a medium-sized pinniped that is found in and near to the Arctic Ocean. [3] It gets its generic name from two Greek words (eri and gnathos) that refer to its heavy jaw. The other part of its Linnaean name means bearded and refers to its most characteristic feature ...

Channichthyidae. The crocodile icefish or white-blooded fish comprise a family (Channichthyidae) of notothenioid fish found in the Southern Ocean around Antarctica. They are the only known vertebrates to lack hemoglobin in their blood as adults. [2] Icefish populations are known to reside in the Atlantic and Indian sectors of the Southern Ocean ...
Polar seas is a collective term for the Arctic Ocean (about 4-5 percent of Earth's oceans) and the southern part of the Southern Ocean (south of Antarctic Convergence, about 10 percent of Earth's oceans). In the coldest years, sea ice can cover around 13 percent of the Earth's total surface at its maximum, but out of phase in the two ...
