 Juveniles commonly shelter among floating rafts of "[[Sargassum]]" and this allows the to disperse over vast distances.This is an omnicorous species which feeds mostly on [[benthic]] [[algae]] and also on as well as on small crabs and molluscs.Off the [[Fernando de Noronha|Fernando de Noronha Archipelago]] in the southeast Atlantic it has been observed feeding on the faeces and vomit of [[spinner dolphin]]s ("Stenella spp") and this feeding off mammalian waste has been suggested to be simple behavioural change from feeding on plankton to picking out drifting particles of waste.
