Description

The bearded ghoul is a stinger (Synanceiidae), a close relative of the stonefish, from the Indo-West Pacific. The species has an irregular, stocky body with warty skin and colourful, finger-like lower pectoral fin rays with which it 'walks' over the bottom. It lies half-buried on sand and silt bottoms of lagoon and seaward reefs 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.
