Northern krill

Northern krill (Meganyctiphanes norvegica) is a species of krill that lives in the North Atlantic Ocean including the Norwegian Sea, North Sea, and parts of the Mediterranean. It is an important component of the zooplankton, providing food for whales, seals, fish, and birds. In the Southern Ocean, Antarctic krill Euphausia superba fills a similar role. M. norvegica is the only species recognized in the genus Meganyctiphanes.

Northern krill supply a crucial link in the North Atlantic Ocean food web, transmitting energy from primary producers to high-level predators. Krill in the North Atlantic Oceans feed on phytoplankton, copepods, and other zooplankton.
