Antarctic krill (Euphausia superba) is a species of krill found in the Antarctic waters of the Southern Ocean. It is a small, swimming crustacean that lives in large schools, called swarms , sometimes reaching densities of 10,000–30,000 individual animals per cubic metre. [ 3 ]
Thysanoessa. Thysanoessa is a genus of the krill [1] that play critical roles in the marine food web. They're abundant in Arctic and Antarctic areas, feeding on zooplankton and detritus to obtain energy. [2] Thysanoessa are responsible for the transportation of carbon and nutrients from surface waters to deeper trophic levels.
Antarctic krill (Euphausia superba) are a keystone species, forming an important part of the Antarctic food web.. At least 235 marine species are found in both Antarctica and the Arctic, ranging in size from whales and birds to small marine snails, sea cucumbers, and mud-dwelling worms.
The Antarctic krill is an important species in the context of biogeochemical cycling [74] [42] and in the Antarctic food web. [ 75 ] [ 76 ] It plays a prominent role in the Southern Ocean because of its ability to cycle nutrients and to feed penguins and baleen and blue whales .
The Adélie penguin is known to feed mainly on Antarctic krill, ice krill, Antarctic silverfish, lanternfish (specifically, the Antarctic lanternfish), amphipods (Themisto gaudichaudii, Cyllopus lucassi, Hyperia and unidentified gammariids), [33] [34] sea krill, glacial squid and other cephalopods [35] (diet varies depending on geographic ...
The crabeater seal (Lobodon carcinophaga), also known as the krill-eater seal, is a true seal with a circumpolar distribution around the coast of Antarctica. They are the only member of the genus Lobodon. They are medium- to large-sized (over 2 m in length), relatively slender and pale-colored, found primarily on the free-floating pack ice that ...
The krill fishery is the commercial fishery of krill, small shrimp -like marine animals that live in the oceans world-wide. The present estimate for the biomass of Antarctic krill (Euphausia superba) is 379 million tonnes. [1] The total global harvest of krill from all fisheries amounts to 150–200,000 tonnes annually, mainly Antarctic krill ...
Binomial name. Thalassoica antarctica. (Gmelin, JF, 1789) range. 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. They feed while swimming but can dive from both the surface and the air.
