Description

The barhead spinefoot is a reef fish of the rabbitfish family (Siganidae) from the western Pacific and eastern Indian Ocean. The species grows to about 30 cm and has a silvery body with yellow tints on the back, fine blue lines and two conspicuous dark oblique bands over the head. It inhabits shallow coastal waters around hard coral reef and sandy areas, often in pairs. As a herbivore it grazes algae and seagrass. The rabbitfish is a local food fish. The dorsal, pelvic and anal spines are venomous and give a painful puncture wound; therefore handle the fish with care.
