Devilfish, or two-stick stingfish (Inimicus filamentosus), lying in wait for prey on the seabed. This fish inhabits reefs and sandy areas in the tropical Indo-Pacific region, from east Africa to Micronesia. Its dorsal fin contains spines linked to venom glands, which protects it from predators. The sting is extremely painful but rarely fatal to humans. The fish is camouflaged to make it appear like a rock or piece of coral rubble. This means its prey, small fish and crustaceans, fail to notice it until it is close enough to engulf them with a sudden leap. Photographed in the Egyptian Red Sea.
