Brief Description
A common bottom-dwelling saltwater fish found along the Pacific coast, known for its ability to camouflage against sandy or rocky substrates.
Characteristics
Features a large, flattened head, a wide mouth, and large pectoral fins. It has a distinctive antler-like preopercular spine with 3-4 points. The coloring is mottled olive-grey or green with silver on the underside and a black spot on the first dorsal fin.
Habitat
Intertidal zones, estuaries, lagoons, and sandy or muddy bottoms. Often found in Puget Sound and along the West Coast.
When to Find It
Year-round; most visible in shallow water during low tide.
Conservation Status
Least Concern
Ecological Role
A vital part of the food web, serving as both a predator of small invertebrates/fish and prey for larger fish, shorebirds, and marine mammals.
Easily Confused With
Other sculpin species (Cottidae family) such as the Buffalo Sculpin. It is distinguished by the specific shape of its branched preopercular spine.
Observation Tips
Look in shallow tide pools or near the water's edge in estuaries. They often bury themselves in sediment, leaving only their eyes visible. Handle with care due to sharp spines.
Interesting Facts
When threatened, they expand their gill covers to flare out their sharp, antler-like spines. They are also unique for their ability to tolerate a wide range of salinities, often moving into brackish or even fresh water.
