The Red Sea stonefish (Synanceia nana) is a saltwater fish of the family Synanceiidae that grows up to 14 cm.
Description
The Red Sea stonefish is a stonefish (Synanceiidae) from shallow reef water of the Red Sea and western Indian Ocean. The species grows to about 14 cm and has a stocky body covered with warts and skin flaps that looks strikingly like an overgrown stone or piece of coral rubble. As a motionless ambush predator it lies buried on the bottom and engulfs passing prey with a lightning-fast suction strike. The dorsal spines inject an extremely powerful venom; a sting is a life-threatening emergency.
