Norwegian Sea
Zooplankton is mostly copepods Calanus finmarchicus and Calanus hyperboreus. C. hyperboreus is strongest in the Arctic waters. They are the main diet of most marine predators. The most important krill species are Meganyctiphanes norvegica, Thyssanoessa inermis, and Thyssanoessa longicaudata. In contrast to the Greenland Sea, there are a lot of calcareous plankton (Coccolithophore and Globigerinida).
