Description

Natterer's niquim toadfish is a truly venomous toadfish (Batrachoididae) from shallow coastal and estuarine water of the western Atlantic off Brazil. The species grows to about 15 cm and has a stocky, scaleless, brown body with a large, flat head and a wide mouth. As a bottom-dweller it often lies half-buried in sand and mud. Unlike most toadfishes it carries hollow dorsal and gill-cover spines linked to venom glands; a sting gives a very painful, strongly swelling wound. Treat as a serious venomous sting.
