Harp seal. The harp seal (Pagophilus groenlandicus), also known as Saddleback Seal or Greenland Seal, is a species of earless seal, or true seal, native to the northernmost Atlantic Ocean and Arctic Ocean. Originally in the genus Phoca with a number of other species, it was reclassified into the monotypic genus Pagophilus in 1844.
Ringed seals are both predators and prey. A predator to zooplankton and fish, the ringed seal is considered a primary consumer as well as a secondary consumer. But the tertiary consumer, or top predator, in the Arctic is the polar bear, feeding mostly on seals, including the ringed seal.
Seals typically swallow their food whole, and will rip apart prey that is too big. [96] [97] The leopard seal, a prolific predator of penguins, is known to violently shake its prey to death. [98] Complex serrations in the teeth of filter-feeding species, such as crabeater seals, allow water to leak out as they swallow their planktonic food. [84]
The leopard seal (Hydrurga leptonyx), also referred to as the sea leopard, [3] is the second largest species of seal in the Antarctic (after the southern elephant seal). Its only natural predator is the orca. [4] It feeds on a wide range of prey including cephalopods, other pinnipeds, krill, fish, and birds, particularly penguins.
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 ...
Hawaiian monk seal. The Hawaiian monk seal (Neomonachus schauinslandi) is an endangered species of earless seal in the family Phocidae that is endemic to the Hawaiian Islands. [2] The Hawaiian monk seal is one of two extant monk seal species; the other is the Mediterranean monk seal. A third species, the Caribbean monk seal, is extinct.
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 (/ ˈfoʊsɪdiː /). They are sometimes called crawling seals to distinguish them from the fur seals and sea lions of the family Otariidae.
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 ...
