It is also found in Alaska from the southeastern Bristol Bay to Demarcation Point during the ice-free seasons of summer and autumn when spotted seals mate and have pups.

[5] The reduction in arctic ice floes due to global warming led to concerns that the spotted seal was threatened with extinction.

The dense fur varies in color from silver to gray and white and is characterized by dark, irregular spots against the lighter background and covering the entire body.

[4][7] Spotted seals are inhabitants of arctic or sub-arctic waters, often in the outer areas of ice floes during the breeding season.

[7] There is also a smaller population of 300 grey spotted seals living in waters off Baekryeong Island located far north of the west coast of South Korea.

In order to prevent the squabble from being fought by water-bombing rocks on Baengnyeong Island, the Hani Sea Water Leopard Artificial Rest Area has been set up.

The numerically largest groups in Alaska are at Kasegaluk Lagoon in the Chukchi Sea, near Cape Espenburg in Kotzebue Sound, and in Kuskokwim Bay on sandbars and shoals, where several thousand may collect.

Spotted seals are believed annually monogamous, and during breeding season, they form "families" made up of a male, female, and their pup, born after a 10-month gestation period.

[4] Based on satellite tracking conducted on Yellow Sea population, it was revealed that seals migrate more than 3,300 km (2,100 mi).

[12] The main threats to the species in China are global warming, marine traffic, industry noise, ocean pollution, and poaching for aquarium exhibition.
