Actinopterygii (ray-finned fishes) > Scorpaeniformes
(Scorpionfishes and flatheads) > Liparidae
Etymology: Liparis: Greek, liparos = fat (Ref. 45335); rutteri: Named after C. Rutter, of the U.S. Fish Commission (Ref. 6885).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 0 - 73 m (Ref. 2850). Temperate
North Pacific: known only from the Bering Sea, the northern Gulf of Alaska (Kodiak) and southeastern Alaska (Yakutat). Records from further south must be considered highly doubtful, especially if specimens measure greater than 6 or 7 cm.
