Fluffy Sculpin

Oligocottus snyderi

The Fluffy Sculpin, known scientifically as Oligocottus snyderi, is a small reef fish found along the coastal northwestern Pacific Ocean, from Kodiak, Alaska to Baja California, Mexico. It reaches a maximum length of about 9 cm and is commonly found in tide pools, often amidst algae. Its body is smooth and lacks scales, with a variable color palette that includes green, pink, and reddish-brown. Distinctive features include a short spine on the snout and tufts of cirri on the head and lateral line. This species inhabits rocky coastal areas, ranging from the mid littoral zone to shallow subtidal zones. It is predominantly found in tide pools, especially those further down the beach where the water remains cooler. The Fluffy Sculpin is a predator, primarily feeding on amphipods and polychaete worms, with larger individuals also consuming small shrimps and crabs. During winter and spring, spawning occurs, with the male using a prehensile anal ray to clasp the female for internal fertilization. Eggs are then laid on rocks and guarded by the male. Divers may encounter the Fluffy Sculpin in shallow rocky areas, particularly in tide pools. It exhibits homing behavior, often returning to its home pool if displaced. The species can breathe air when out of water, allowing it to leave tide pools when conditions become inhospitable. Its conservation status has not been evaluated by the IUCN.
