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]
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 ...
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.
Examples are krill-eating crabeater seals, crustacean-eating ringed seals, squid specialists like the Ross seal and southern elephant seal, and the bearded seal and walrus, which specialize on benthic invertebrates. [85] Pinnipeds may hunt solitarily or cooperatively. The former behavior is typical when hunting non-schooling fish, immobile or ...
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]
This places the beaked whales as some of the few food competitors of the sperm whale. Other possible squid predators include the pilot whale, killer whales, larger southern elephant seals, Patagonian toothfish, [40] southern sleeper sharks (Somniosus antarcticus), Antarctic toothfish, and albatrosses (e.g., the wandering and sooty albatrosses).
