The sea has about 80 species of zooplankton, more than 70 species of phytoplankton, and nearly 700 species of polychaetes, bryozoans, crustaceans and mollusks. But there are not very many of the animals because of the cold climate. Important fish species include polar cod, Arctic cod, saffron cod, Arctic char, chum salmon, Arctic cisco, least cisco, lake whitefish, broad whitefish, Pacific herring, fourhorn sculpin, inconnu and flatfish.
