Bearded scorpionfish (Scorpaenopsis barbata). This predator gets its name from skin extensions around its mouth. It lies motionless for hours, camouflaged amongst the rocks and coral, until a smaller fish comes within range of a rapid lunge. The scorpionfish has a row of spines on its back, linked to poison glands, which it uses for defence. Photographed in the Red Sea.
