There are 15 known cephalopod species in Greenland waters and at least five are known to inhabit the Greenland Sea ecoregion, including Bathypolypus arcticus, Opisthoteuthis borealis, Cirroteuthis muelleri, Stauroteuthis syrtensis, and Gonatus fabricii. Squid taken as bycatch in the shrimp fishery are often used as bait, and there is no targeted fishery on cephalopods in the ecoregion. The squid Gonatus fabricii has been shown to bioaccumulate trace elements, including mercury.
