Description

The pitted stonefish is a stonefish from the western Pacific, from southern Japan to northern Australia. The species grows to about 15 cm and has a stocky, lumpy body with pits and protuberances that hides perfectly among stones and on reef bottoms. As a motionless ambush predator it waits until prey comes within reach. It carries strongly venomous dorsal fin spines with venom glands; a sting is extremely painful and dangerous. The IUCN assesses the species as Least Concern (LC).
