Description

Greene's midshipman is a toadfish (Batrachoididae) from the eastern Pacific. The species has a flattened head, a broad mouth and rows of light-producing organs (photophores) on the belly and flanks, arranged in rows like a ship's portholes, hence the name. It lives on soft bottoms in shallow water to about 27 m. As a bottom predator it feeds on small crustaceans and small fishes. The dorsal fin and gill-cover spines are venomous and give a painful puncture wound.
