Woolly Sculpin

Clinocottus analis

The Woolly Sculpin is a ray-finned fish found along the eastern Pacific coastline, from northern California to central Baja California. This species is characterized by its elongated, speckled body and a large, wide head with eyes positioned on top. It can grow up to 18 centimeters in length and lacks scales, instead having gills with sharp spines. The Woolly Sculpin is typically found in intertidal zones, residing among tide pools and algae-covered rocks at depths up to 18 meters. It is well adapted to survive in rapidly changing environmental conditions, including fluctuations in temperature and salinity. This species is a bottom-dweller, feeding mainly on crustaceans like amphipods, as well as fish eggs, larvae, polychaetes, and mollusks. It is capable of breathing air and can survive out of water for up to 24 hours, allowing it to leave tide pools if conditions become unfavorable. Woolly Sculpins are non-migratory and exhibit homing behavior, often returning to the same tide pools. Reproduction occurs in shallow coastal waters, with females laying multiple batches of eggs throughout the year. The larvae settle in tide pools and grow rapidly. The Woolly Sculpin is not evaluated by the IUCN, and it is preyed upon by birds such as the great blue heron, snowy egret, and willet.
