Description

This species reaches about 38 centimeters in length. Much of the body has black-edged blue and yellow stripes, and the top of the head is striped with yellow. The belly is grayish. The pectoral fins have darkened rays and the pelvic fins are yellow-brown with black margins. Individuals from around the Philippines vary in coloration.[2] The sharp, forward-pointing spines on the caudal peduncle are venomous.[3]

Distribution

A. lineatus occurs in the Indian Ocean from East Africa to the western Pacific Ocean to the Great Barrier Reef, Japan, Polynesia,[3] and Hawaii.

Habitat

The lined surgeonfish is associated with reefs, living in marine waters just a few meters deep. It is benthopelagic.[3]

Behaviour

The fish is territorial, with a large male defending a feeding territory and a harem of females. The adults may also school, and they gather en masse during spawning. The juvenile is solitary. The fish is mostly herbivorous, but might eat crustaceans at times.[3] Most of its diet is algae. It grazes during the day.[1]

Human uses

This species is of commercial and ornamental value. It is especially important among the reef fishes of American Samoa. In some areas it is heavily exploited, but it lives in many protected zones and in general it is widespread and common.[1]
