Northern elephant seals eat a variety of prey, including mesopelagic fish such as myctophids, deep-water squid, Pacific hake, pelagic crustaceans, relatively small sharks, rays, and ratfish. [ 25 ] [ 16 ] [ 26 ] Octopoteuthis deletron squid are a common prey item, one study found this species in the stomachs of 58% of individuals sampled off ...
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.
Within marine food webs, H. heteropsis plays an important role in the diets of tuna, porpoises, blue sharks, sperm whales, elephant seals, and albatross. [4] Not much is known about the diet of H. heteropsis itself, although limited stomach content evaluations show that they feed on fish, crustaceans, and smaller squids. [4]
Pinnipeds range in size from the 1.1 m (3 ft 7 in) and 50 kg (110 lb) Baikal seal to the 6 m (20 ft) and 3,700 kg (8,200 lb) male southern elephant seal, which is also the largest member of Carnivora. [1]
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.
P. glacialis is known to feed on many crustaceans, fish, lanternfish, Antarctic krill, and Antarctic silverfish, and has been known to practice cannibalism. [4] Animals known to routinely feed on glacial squid include the Antarctic petrel, light-mantled albatross, Ross seal, southern elephant seal, Weddell seal, Patagonian toothfish, wandering albatross, grey-headed albatross, the Adélie ...
At sea, they can dive up to 2,000 feet below the surface for up to 20 minutes at a time in search of “rays, skates, rat fish, squid, and small sharks.” Elephant seals can reach over 13 feet in ...
A southern elephant seal's eyes are large, round, and black. The width of the eyes, and a high concentration of low-light pigments, suggest sight plays an important role in the capture of prey. Like all seals, elephant seals have hind limbs whose ends form the tail and tail fin. Each of the "feet" can deploy five long, webbed fingers.
