Description

The leaf scorpionfish is a scorpionfish (Scorpaenidae) from the Indo-Pacific. The species has a strongly laterally compressed, leaf-shaped body that can occur in red, yellow, brown, white or black; it sways back and forth like a leaf in the current. It inhabits reef flats, outer reef slopes and current-swept channels. With its large mouth it gulps small fishes and crustaceans as an ambush hunter. It regularly sheds its skin. The dorsal fin spines carry venom and cause intense pain when stung.
