Description

The mottled spinefoot is a reef fish of the rabbitfish family (Siganidae) from the Indo-West Pacific. The species grows to about 40 cm and has an oval, olive-brown to greyish body densely studded with small pale spots; the colour can change quickly. It inhabits algal and seagrass flats and shallow lagoon and coastal reefs, where it grazes in schools. As a herbivore it feeds mainly on algae and seagrass. The rabbitfish is a valued food fish. The numerous dorsal, pelvic and anal spines are venomous and give a painful puncture wound; therefore handle the fish with great care.
