Description

The spotted hawkfish is a hawkfish (Cirrhitidae) from the Indo-West Pacific. The species has a pale body with red-brown blotches and small tufts (cirri) on the tips of the dorsal fin spines. Like all hawkfishes it lacks a swim bladder and props itself on coral and rock with its thickened lower pectoral fin rays, where it sits motionless on the lookout. It inhabits rocky and coral-rich coastal reefs and sometimes enters harbours and estuaries. As an ambush hunter it springs on small crustaceans and small fishes. The species is harmless to humans.
