Scalyhead Sculpin

Artedius harringtoni

The Scalyhead Sculpin is a demersal fish native to the eastern Pacific Ocean, ranging from Kodiak Island, Alaska, to San Miguel Island, California. This species is often found in intertidal and subtidal rocky areas, frequently around pilings, at depths up to 21 meters. Divers can identify this fish by its distinctive orange linings on the gills and the orange or red lines running through its eyes. It also features cirri above each eye, which adds to its unique appearance. The Scalyhead Sculpin exhibits sexual dimorphism, with males growing up to 10 centimeters in length. This species is known for its camouflage abilities, blending seamlessly into its rocky surroundings. It is a territorial fish, with males guarding clutches of eggs until they hatch. The Scalyhead Sculpin reproduces through internal fertilization, and males are known to be quite protective of their territory, especially during the breeding season. In terms of diet, the Scalyhead Sculpin is a forager and predator, feeding on small invertebrates and occasionally the eggs of other fish species, such as the lingcod. Divers encountering this fish can expect a harmless interaction, as it poses no threat to humans.
