Description

The stargazing stonefish is a stonefish (Synanceiidae) from shallow coastal and estuarine water of the Indo-West Pacific. The species grows to about 15 cm and has a stocky body set with skin flaps and a steep head with an almost vertically upturned mouth and high-set eyes. As an ambush predator it lies buried on sand and mud bottoms and sucks in passing prey. The dorsal spines are venomous and can give a very painful puncture wound.
