Migration/Dispersal patterns

Spotted seals migrate south from the Chukchi Sea through the Bering Strait in October-November ahead of the advancing sea ice, and overwinter in the Bering Sea in the pack ice over the continental shelf. During spring, they are distributed mainly in the ice front and move to coastal habitats after the sea ice retreats.

Social system/Group size

Usually solitary. They haul in large groups during summer and form small groups of a male, female and her pup in spring.

Major threats

They are hunted (mainly in China to use the genitals and the fur as medicine).
