The harbor (or harbour) seal (Phoca vitulina), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere. 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 ...
Freshwater seals are pinnipeds which live in freshwater bodies. The group is paraphyletic in nature, the uniting factor being the environment in which these pinnipeds live. The vast majority of all modern seals live solely in saltwater habitats though this is likely due to the rarity of sufficiently large freshwater bodies rather than the ...
Harp seals spend relatively little time on land compared with time at sea. They are social animals and can be quite vocal in groups. Within their large colonies, smaller groups with their own hierarchies form. [2] Groups of several thousand form during pupping and mating season. [17] Harp seals can live over 30 years in the wild.

Grey seals are vulnerable to typical predators for a pinniped mammal; their primary predator would be the orca or killer whale, but certain large species of sharks are known to prey on grey seals in North American waters, particularly great white sharks and bull sharks but also, upon evidence, additionally Greenland sharks. Some grey seal ...
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. Seals live in the oceans of both hemispheres and, with the exception of the more tropical monk seals, are mostly confined to polar, subpolar, and ...
Elephant seals or sea elephants are very large, oceangoing earless seals in the genus Mirounga.Both species, the northern elephant seal (M. angustirostris) and the southern elephant seal (M. leonina), were hunted to the brink of extinction for lamp oil by the end of the 19th century, but their numbers have since recovered.
Ringed seals require sea ice to live and reproduce. They live most of their lives alone, only grouping together into colonies when they are on sea ice to molt, mate, or rest. [19] Without access to sea ice, ringed seals are unable to sustain life, which further affects trophic levels both above and below. Ringed seals are both predators and prey.
