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.
The earless seals, phocids, or true seals are one of the three main groups of mammals within the seal lineage, Pinnipedia. All true seals are members of the family Phocidae (/ ˈ f oʊ s ɪ d iː /). They are sometimes called crawling seals to distinguish them from the fur seals and sea lions of the family Otariidae.
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.
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.
Adult harp seals grow to be 1.7 to 2.0 m (5 ft 7 in to 6 ft 7 in) long and weigh from 115 to 140 kg (254 to 309 lb). [1] The harp seal pup often has a yellow-white coat at birth due to staining from amniotic fluid, but after one to three days, the coat turns white and stays white for 2–3 weeks, until the first molt.
