Description
The Mottled Sculpin is a bottom-dwelling freshwater fish native to North America, characterized by its large head, broad pectoral fins, and mottled brown coloration for camouflage. It prefers cool, clear, well-oxygenated streams and rivers with rocky substrates, often hiding among rocks and debris. This species is predatory, feeding on insects, crustaceans, and small fish.
