Pinnipedia is an infraorder of mammals in the order Carnivora, composed of seals, sea lions, and the walrus. A member of this group is called a pinniped or a seal. [a] They are widespread throughout the ocean and some larger lakes, primarily in colder waters.
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 ...
The skull of the leopard seal. The leopard seal has a distinctively long and muscular body shape when compared to other seals. The overall length of adults is 2.4–3.5 m (7.9–11.5 ft) and their weight is in the range 200 to 600 kilograms (440 to 1,320 lb), making them the same length as the northern walrus but usually less than half the weight.

Global efforts such as the Southern elephant seals as oceanographic samplers [43] and the Marine Mammals Exploring the Oceans Pole to Pole projects [44] have led to the collection of a large suite of long-term coupled behavioural-oceanographic data. As part of these projects, satellite-relay data loggers were attached to southern elephant seals ...
The bearded seal is unique in the subfamily Phocinae in having two pairs of teats, a feature it shares with monk seals. Bearded seals reach about 2.1 to 2.7 m (6.9 to 8.9 ft) in nose-to-tail length and from 200 to 430 kg (441 to 948 lb) in weight. [5] The female seal is larger than the male, meaning that they are sexually dimorphic.
