Fin's Fish Guide

Arctic coastal waters of the Arctic Ocean and adjacent seas, on stony and rocky bottoms of cold, shallow to moderately deep water.
Description
The leatherfin lumpsucker is a small, globular lumpsucker of the family Cyclopteridae (lumpsuckers) reaching about 10 cm. The stocky body has a rough, knobbly skin; as in the common lumpsucker the pelvic fins are fused into a powerful sucking disc, with which the fish anchors itself firmly to stones, even in current and surf. The species is adapted to cold water and lives on stone and rock bottoms of the Arctic coastal waters of the Arctic Ocean and adjacent seas, around Siberia and North America. On the bottom it searches for small crustaceans, worms and zooplankton. The male guards the clutch laid on stones until it hatches. Because of its small size it has no fishery importance.
