Cottidae, commonly known as sculpins, is a family of fish primarily found in cold, freshwater environments. They are characterized by their flattened bodies, large heads, and spiny fins. Sculpins are often bottom-dwellers, using their pectoral fins to navigate rocky substrates and hunt for small invertebrates. These fish are distributed mainly in the northern hemisphere, particularly in the North Atlantic and North Pacific regions. Sculpins play a vital role in their ecosystems, serving as both predators and prey. Some species are also popular among anglers for their unique appearance and behavior.
