The sea hosts about 80 species of zooplankton, more than 70 species of phytoplankton, and nearly 700 species of polychaetes, bryozoans, crustaceans and mollusks, but their total volume is relatively small owing to the cold climate. Major fish species include polar cod ("Boreogadus saida"), Arctic cod ("Arctogadus glacialis"), saffron cod ("Eleginus gracilis"), Arctic char ("Salvelinus alpinus"), chum salmon ("Oncorhynchus keta"), Arctic cisco ("Coregonus autumnalis"), least cisco ("Coregonus sardinella"), lake whitefish ("Coregonus clupeaformis"), broad whitefish ("Coregonus nasus"), Pacific herring ("Clupea pallasii"), fourhorn sculpin ("Myoxocephalus quadricornis"), inconnu ("Stenodus leucichthys") and flatfish.
