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 animals per cubic metre. [ 3 ]
Given this, Arctic habitats are projected to shift vigorously in the next years, impacting krill growth and abundance of nutrients such as chlorophyll a. [8] The movement of krill in various geographic locations result in a movement of energy in the food web. Carbon, caloric, and lipid concentrations vary depending on the specie and the location.
At this stage in their growth they are small enough to benefit from surface tension in order to climb vertical walls. [7] In fresh water they develop pigmentation, turn into elvers (young eels), and feed on creatures such as small crustaceans, worms, and insects. For 10 to 14 years they mature, growing to a length of 60 to 80 cm.
This is a list of maximum recorded animal lifespans in captivity.Only animals from the classes of the Chordata phylum are included. [1] On average, captive animals (especially mammals) live longer than wild animals.
Krill also release faecal pellets (3) whilst they feed, which can sink to the deep sea but can be consumed (coprophagy) and degraded as they descend (4) by krill, bacteria and zooplankton. In the marginal ice zone, faecal pellet flux can reach greater depths (5). Krill also release moults, which sink and contribute to the carbon flux (6).

Krill is a rich source of protein and omega-3 fatty acids which are under development in the early 21st century as human food, dietary supplements as oil capsules, livestock food, and pet food. [10] [11] [12] Most krill is processed to produce fish food for use in aquariums and aquacultures. The krill is sold freeze-dried, either whole or ...
In particular, the biomass of consumers (copepods, krill, shrimp, forage fish) is larger than the biomass of primary producers. This happens because the ocean's primary producers are tiny phytoplankton which grow and reproduce rapidly, so a small mass can have a fast rate of primary production .
