The term "Sculpin" refers to a group of fish belonging to the family Cottidae, commonly found in both freshwater and marine environments. These fish are characterized by their spiny fins, broad heads, and often unique body shapes. Sculpins are typically bottom-dwellers, using their pectoral fins to navigate rocky substrates. Sculpins are known for their diverse habitats, ranging from rivers and lakes to ocean floors. They play a role in the ecosystem as both predators and prey, feeding on small invertebrates and serving as food for larger fish and birds. Some species, like the Pacific Sculpin, are particularly noted for their distinctive appearance and behavior.
