Description

The Atlantic midshipman (Porichthys plectrodon) is a toadfish-like bottom fish of the family Batrachoididae from the western Atlantic. The species has an elongate, scaleless body with a broad head and bears rows of light organs (photophores) along the belly and flanks, resembling the buttons of a sailor's uniform, hence the name. It reaches about 29 cm and lives on mud and sand bottoms, especially on shallow offshore banks such as shrimp grounds. As a bottom dweller and ambush predator it feeds on small fishes and invertebrates. Like other toadfishes it can produce grunting sounds.
