A sculpin is a type of fish that belongs to the superfamily Cottoidea in the order Scorpaeniformes. As of 2006, this superfamily contains 11 families, 149 genera, and 756 species.
Gobies are found in many types of habitat, including the area of ocean and fresh waters. They live in rivers, submarine canyons, kelp forests, and shallow coastal habitats such as tidepools.
Gobies are bottom-dwelling fish that live at the bottom of ponds. Their pectoral fins are smooth on the upper edge and webbed with sharp rays along the lower edge, a modification that makes them specialized for capture of the substrate. This adaptation helps the fish anchor in fast water.
