Description

The Japanese devil stinger is a stinger (Synanceiidae), a close relative of the stonefish, from the northwestern Pacific. The species has an irregular, stocky body with warty skin, upward-pointing eyes and colourful, finger-like lower pectoral fin rays with which it 'walks' over the bottom. It lies half-buried on sand and mud bottoms and waits as an ambush hunter for small fishes and crustaceans. The dorsal fin spines carry potent venom; a sting causes intense pain and requires medical care.
