Biology: |
Inhabits shallow waters, over turtle grass, sand or rocky bottom and around coral reefs (Ref. 3725). Young commonly found among floating Sargassum weeds (Ref. 3725). Feeds on plants, mainly on benthic algae, as well as on small crabs and mollusks (Ref. 6547). Also feeds on spinner dolphins?feces and vomits at Fernando de Noronha Archipelago, southeast Atlantic. The offal feeding may be regarded as a simple behavioral shift from plankton feeding to drifting offal picking (Ref. 48727). Marketed fresh (Ref. 3725).
