With a catfish-shaped body and face, sea robins come in a wide range of colors: Red-brown and orange to subtler hues of silver and gray. Yet sea robins are most notable for their distinctively large, fan-shaped dorsal fins and for their six leg-like appendages.

Some types of “walking” fish called sea robins can use their taste bud-covered legs to detect prey buried beneath the sandy covering of the seafloor.

Sea robins, a type of ocean-dwelling fish, are uniquely adapted to life on the seafloor. Their six leg-like structures allow them to move, burrow, and hunt with such skill that other fish often gather nearby to steal their leftovers.
