Originally in the genus Phoca with a number of other species, it was reclassified into the monotypic genus Pagophilus in 1844.
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.
Seals typically swallow their food whole, and will rip apart prey that is too big. [97] [98] The leopard seal, a prolific predator of penguins, is known to violently shake its prey to death. [99] Complex serrations in the teeth of filter-feeding species, such as crabeater seals, allow water to leak out as they swallow their planktonic food. [85]
Known predators are killer whales, sharks, male New Zealand sea lions, and possibly leopard seals. [1] New Zealand sea lions are also known to target pups as their prey. [18] Several regurgitations by sea lions have been found to contain remains of fur seal pups, some with plastic tags previously attached to female fur seal pups. [18]

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.
Pinnipedia is an infraorder of carnivores, composed of seals, sea lions, and the walrus. A member of this group is called a pinniped or a seal. The clade contains three families: Odobenidae, comprising the walrus; Otariidae, the eared seals, split between the sea lions and fur seals; and Phocidae, the earless or true seals.
Hawaiian monk seals grow to be 6-7 feet long, weigh 400-600 pounds, and can live more than 30 years. Males and females are generally the same size — the only way to tell them apart is to look at ...
