Krill

Krill refers to marine shrimp-shaped crustaceans of the order Euphausiacea . They are part of the plankton ( zooplankton ).

Antarctic krill

The best known species is the Antarctic krill ( Euphausia superba Dana). Krill forms huge schools . Krill is now used extensively by humans: not only as food, but also in the cosmetics industry , for pharmaceutical production and in alternative medicine (especially krill oil ) and as animal feed in fish farms .

etymology

The word "krill" comes from Norwegian . It is said to be derived from the now uncommon Dutch expression "kriel" for "a little thing" (still used today for bantams and small potatoes). Norwegian whalers used this term for the small crustaceans that they encountered en masse in the stomachs of captured whales, especially the blue whale , during whaling ; they distinguished between large or "storkrill" ( Meganyctiphanes norvegica ) and small or "smaakrill" ( Thysanoessa species, especially Thysanoessa inermis ). The term was later transferred to the Antarctic krill.
