Antarctic Krill
Antarctic krill (''Euphausia superba'') is a species of krill found in the Antarctica, 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. It feeds directly on minute phytoplankton, thereby using the primary production energy that phytoplankton originally derive from the sun in order to sustain its pelagic biological life cycle, life cycle. It grows to a length of , weighs up to , and can live for up to six years. A key species in the Antarctic ecosystem and in terms of biomass (ecology), biomass, ''E. superba'' is one of the most abundant animal species on the planet, with a cumulative biomass of approximately . Life cycle The main spawn (biology), spawning season of Antarctic krill is from January to March, both above the continental shelf and also in the upper region of deep sea oceanic areas. In the typical way of all krill, the male at ...

Euphausia Lucens
''Euphausia lucens'' is a species of krill endemic to the temperate waters of the Southern Hemisphere. Distribution and habitat ''Euphausia lucens'' is an epipelagic species restricted to the Southern Hemisphere, where it has a circumpolar distribution including parts of the Atlantic, Indian and Pacific Oceans. It is most common in the temperate waters between 41°S and 45°S, avoiding the cooler waters of the Southern Ocean, but may be found as far north as 37°S and as far south as 52°S. It prefers water temperatures between and typically occurs in waters no shallower than deep; it is generally not encountered closer to the coast. In the eastern South Pacific, ''Euphausia lucens'' occupies the area directly north of the range of '' Euphausia vallentini''. Description Adult ''Euphausia lucens'' measure long. The eyes are large and spherical and the rostrum is noticeably short. There is a small tooth on the lower edge of the carapace, but the abdomen lacks any spines. Adu ...
