Sculpins are small, bottom-dwelling fish found in both freshwater and saltwater environments. They belong to the family Cottidae and are known for their unique body shapes, which often include large heads and spiny fins. Sculpins typically inhabit rocky or sandy substrates, where they can camouflage themselves from predators. These fish are primarily carnivorous, feeding on small invertebrates and other fish. Sculpins are recognized for their ability to adapt to various habitats, including rivers, lakes, and coastal areas. Some species, like the Pacific sculpin, are popular among anglers due to their interesting appearance and behavior.
