Cyclopteridae - Lumpfishes

The Cyclopteridae are a family of marine fishes, commonly known as lumpsuckers or lumpfish, in the order Scorpaeniformes. They are found in the cold waters of the Arctic, North Atlantic, and North Pacific oceans. The greatest number of species are found in the North Pacific.

The family name Cyclopteridae derives from the Greek words κύκλος (kyklos), meaning circle, and πτέρυξ (pteryx), meaning wing or fin, in reference to the circle-shaped pectoral fins of most of the fish in this family.
