The Black spinefoot (Siganus spinus) is a saltwater fish of the family Siganidae that grows up to 28 cm.
Description
The little spinefoot is a rabbitfish of the family Siganidae from the Indo-Pacific. The species grows to about 28 cm and has a deep, laterally compressed body with a fine marbled pattern that provides camouflage. Adults inhabit shallow coral reef flats and also enter rivers; they occur in small schools of usually fewer than ten individuals. As a herbivore it grazes algae from the reef. The dorsal, pelvic and anal spines are venomous and can give a painful puncture wound, so handle the fish with care. The little spinefoot is eaten locally.
