The Family Cyclopteridae includes a group of fish species commonly known as the lumpfish family. These fish are distributed throughout the North Atlantic and Arctic regions, and they are known for their unique physical characteristics, including a flattened head and large, sucker-like pelvic fins. Other synonyms for the Family Cyclopteridae include the snailfish family and the lumpsuckers; the latter term comes from their suction cups, which allow them to attach to rocks and other surfaces in their environment. Despite their unusual appearance, members of this family are commercially harvested for their high-quality roe, which is considered a delicacy in some cultures.
