The Family Cottidae, commonly known as sculpins, comprises more than 300 species of cold-water fish found throughout the Northern Hemisphere, particularly in the Pacific and Arctic Oceans. Synonyms for this family name include Cottids, sea ravens, bullheads, and father lasher. These bottom-dwelling fish have large heads, spiny fins, and flattened bodies, which help them blend in with their rocky surroundings and avoid predators. Sculpins are primarily carnivorous and feed on small invertebrates, fish eggs, and even other fish. They play an important role in commercial and recreational fisheries and are a popular subject for aquarium enthusiasts.
