Description

The estuarine stonefish is a stonefish (Synanceiidae) from the Indo-West Pacific and is one of the most venomous fishes in the world. The species has a stocky, warty body that looks like an algae-covered stone; it lies largely buried in sand or mud of coastal reefs and estuaries and is therefore hard to see. As an ambush hunter it swallows passing fishes and shrimps in a flash. The thirteen dorsal fin spines bear powerful venom glands; a sting - often from stepping on it - is extremely painful and can be fatal. Seek immediate medical help for a sting.
