The species grows to about 20 cm and has a stocky, greyish body and characteristically lives against the underside of the pack ice, sheltering among the ice crystals. Antifreeze compounds in its blood prevent freezing. It feeds on small zooplankton, especially krill and amphipods. The fish is harmless to humans.
