Description
The Coastal Riffle Sculpin is a bottom-dwelling freshwater fish native to the Pacific Northwest. It is characterized by its mottled brown coloration, large head, and fan-like pectoral fins, which help it hold position in fast-flowing currents. This species is a territorial ambush predator, feeding on aquatic invertebrates and small fish.
