Over half of this biomass is eaten by whales, seals, penguins, seabirds, squid, and fish each year. Most krill species display large daily vertical migrations, providing food for predators near the surface at night and in deeper waters during the day. Krill are fished commercially in the Southern Ocean and in the waters around Japan.
Thus invertebrates such as squid and shrimp are also referred to as "forage fish". Even the tiny shrimp-like creatures called krill, small enough to be eaten by other forage fish, yet large enough to eat the same zooplankton as forage fish, are often classified as "forage fish". [5]
[4] [5] For example, a large marine vertebrate may eat smaller predatory fish but may also eat filter feeders; the stingray eats crustaceans, but the hammerhead eats both crustaceans and stingrays. Animals can also eat each other; the cod eats smaller cod as well as crayfish, and crayfish eat cod larvae. The feeding habits of a juvenile animal ...

Antarctic krill is the keystone species of the Antarctic ecosystem beyond the coastal shelf, [22] and provides an important food source for whales, seals (such as leopard seals, fur seals, and crabeater seals), squid, icefish, penguins, albatrosses and many other species of birds. Crabeater seals have even developed special teeth as an ...
The Antarctic petrel (Thalassoica antarctica) is a boldly marked dark brown and white petrel, found in Antarctica, most commonly in the Ross and Weddell Seas.They eat Antarctic krill, fish, and small squid.
It feeds on a wide variety of creatures. Young leopard seals usually eat mostly krill, squid and fish. Adult seals probably switch from krill to more substantial prey, including king, Adélie, rockhopper, gentoo, emperor and chinstrap penguins, and less frequently, Weddell, crabeater, Ross, and young southern elephant seals.
