Baikal seals can dive up to depths of 400 m (1,300 ft) [4] and stay underwater for more than 40 minutes. [1] Most dives last less than 10 minutes and generally only 2–4 minutes. [1] Baikal seals have two litres more blood than any other seal of their size and can stay underwater for up to 70 minutes if they are frightened or need to escape ...

The most widely distributed species of pinniped (walruses, eared seals, and true seals), they are found in coastal waters of the northern Atlantic and Pacific oceans, Baltic ...
Harbor seals (common seals) are also known to enter estuaries and freshwater rivers in pursuit of their prey. [8] In addition a unique subspecies in Quebec and an isolated population of harbor seals in Alaska are known to inhabit freshwater lakes for the duration of the year. They are also known to frequently migrate to the Western Arctic.

Harp seals combine anatomical and behavioral approaches to managing their body temperatures, instead of elevating their metabolic rate and energy requirements. [8] Their lower critical temperature is believed to be under −10 degrees Celsius in air. [9] Blubber insulates the harp seal's core but does not insulate the flippers to the same extent.
Spotted seals dive to depths up to 300 m (980 ft) while feeding on a variety of ocean prey. Juveniles eat primarily krill and small crustaceans while adults eat a variety of fish including herring, arctic cod, pollock, and capelin. [4] They do not seem to vocalize a lot, although not much is known about their vocalizations.
Upon spotting a seal, it walks to within 100 yards (90 m), and then crouches. If the seal does not notice, the bear creeps to within 30 to 40 feet (9 to 10 m) of the seal and then suddenly rushes to attack. [71] A third hunting method is to raid the birth lairs that female seals create in the snow. [70] They may also feed on fish. [72]
Caspian seals migrate back to the southern part of the Caspian Sea after the breeding season and molting in late April because the north begins to warm with constant ice melting. The southern region of the Caspian Sea has deep, colder waters where the seals spend the summer months.
