Euphausia superba is a species of krill found in the Antarctic waters of the Southern Ocean. This species is the primary food source for many larger marine organisms and is a key species in the ecosystem. It is a shrimp-like crustacean that lives in large schools and feeds directly on minute phytoplankton, thereby using the primary production energy that the phytoplankton originally derived from the sun in order to sustain their pelagic life cycle. In terms of biomass, currently the most abundant species on Earth.
