Ecology Summary - Acanthurus chirurgus

言語:

主な参照	Randall, J.E., 1967
意見	Inhabits shallow reefs or rocky areas. Found in loose aggregations (Ref. 9710). Mainly diurnal. Ingests sand when feeding on algae (Ref. 13442). The spine on both sides of the caudal peduncle may inflict painful wounds (Ref. 5217). Minimum depth reported from Ref. 27115. Also cleaned by Thalassoma noronhanum observed at Fernando de Noronha Archipelago off northeastern Brazil (Ref. 36301), by Elacatinus figaro observed off the coast of São Paulo, southeastern Brazil (Ref. 40102), and by Pomacanthus paru observed at the reefs of the Abrolhos Archipelago, off eastern Brazil (Ref. 40094). Predominantly inhabits forereefs (Ref. 128694). Showed selection for sand and chlorophytes (Ref. 55789). Roving herbivore (Ref. 57616). Also Ref. 33499. Exhibits facultative feeding. Group of this species was observed to be feeding on a tuna head, possibly Euthynnus sp., at a depth of 4.5 m. It is common in this diving site to see fish flesh as it's typically used in fishing and diving activities as bait to attract fish and sharks (Ref. 122732).
