The Arctic alligatorfish[2] (Aspidophoroides olrikii) is a fish in the family Agonidae (poachers).[3] It was described by C.F. Lütken in 1877.[4] It is a marine and brackish-water dwelling fish which is known from the Arctic, the northwestern Atlantic and northwestern and northeastern Pacific Ocean, including Canada , Greenland, Siberia, the Barents Sea, the White Sea, the Kara Sea, the Chukchi Sea, the Bering Sea, the Bering Strait, and the Anadyr Gulf. It dwells at a depth range of 7–520 metres, in salinities of 30-35 ppt, and leads a benthic lifestyle, inhabiting sand and mud bottoms. It mostly lives in temperatures below 0 °C, but on rare occasions has been found in temperatures of 2-3 °C. Males can reach a maximum total length of 8.6 centimetres.[3]
The diet of the Arctic alligatorfish consists of amphipods such as Dyopedos porrectus and Paradulichia typica, bivalves such as Macoma calcarea, ostracods, isopods, and nemertine worms.[5]
