Main Ref. Randall, J.E., 1956
Remarks Occur in lagoon and seaward reefs with hard substrate; young abundant in tide pools (Ref. 3145, 48637). Often feeding near freshwater run-offs where certain algae grow on rocks that are grazed (Ref. 48637). Feed on filamentous algae in large aggregations. Roving herbivore (Ref. 57615).
