Ecology Summary - Scarus ghobban

Language:

Main Ref.	Sano, M., M. Shimizu and Y. Nose, 1984
Remarks	Inhabit lagoon and seaward reefs (Ref. 1602), in slopes and drop-offs (Ref. 48636). Males common in atolls where they live mainly around the inner and outer edges of barrier reefs at depths of about 30 ft; females prefer deeper habitat (Ref. 4821). Small juveniles inshore on algae reef habitat. Enter silty, murky environments (Ref. 5490). Adults solitary (but may sometimes occur in small groups), juveniles in groups (Ref. 9710, 48636). Feed by scraping algae from rocks and corals (Refs. 5227, 129713). Roving herbivore (Refs. 43650, 57615, 127989). Protogynous hermaphrodite. Dwells in rocky substrates in shallow waters (Ref. 127989).
