Description

The spiny searobin is a bottom-dwelling marine fish of the searobin family (Triglidae) of the western Atlantic. The species grows to about 17 cm and has an elongate body with a large bony head shield and broad, fan-like pectoral fins. The lower fin rays are separated into finger-like feelers with which the fish 'walks' over the bottom and probes for prey. It lives on soft bottoms of the continental shelf and feeds on crustaceans and small bottom animals. The species is of little commercial value and is harmless to humans.
