While tidepooling in California we found many cool creatures, including a few examples of this neat fish.
Sculpins make up a very large family of fish, with about 300 species. They are characterized by an oversized head and fanlike pectoral fins.
Most species are found in Arctic or temperate waters and are bottom dwellers. They typically occur in shallow or intertidal zones, though some species occur in the deep ocean and others in fresh water.
Sculpins differ from many other bony fish because they lack a swim bladder. A swim bladder is a gas-filled sack that a fish can expand or deflate to control its buoyancy in the water column. Lack of a swim bladder fits the sculpin’s bottom-dwelling habits.
Most species of Sculpin have cryptic coloration (brown or green to blend in with silt and algae). They are generally small fish, ranging 5 to 6 inches in length.
The Padded Sculpin feeds mainly on small invertebrates; in turn, it is an important food sources for other fish.
Sculpins are also known as “Bullheads” or “Sea Scorpions” and even some very unflattering terms, such as “Double Uglies.”
