description Spiny Lumpsucker Overview

The spiny lumpsucker is a species of marine ray-finned fish belonging to the family Cyclopteridae, found in the North Pacific Ocean. It is characterized by a rotund body covered in distinct, sharp tubercles and a modified pelvic fin that functions as a suction disc. This adhesive disc allows the fish to anchor itself to rocks and seaweed in its harsh benthic environment. They primarily inhabit cold, deep waters and feed on small benthic invertebrates.
