Western Atlantic: Brazil. Caribbean (described from Cuban specimens) species refers to Stegastes xanthurus (formerly considered as a junior synonym of S. variabilis). Populations from Brazil and the Caribbean are genetically very distinct (Roberstson & van Tassell, 2012; accessed 08 August 2016; http://biogeodb.stri.si.edu/caribbean/en/thefishes/species/3884).

Biología     Glosario (por ej. epibenthic)

Adults inhabit inshore and offshore coral reefs. They feed mainly on benthic algae but also on sponges, ascidians and anemones while juveniles feed on invertebrates like harpacticoid copepods and nemerteans (Ref. 9626). Often solitary (Ref. 9626). Juveniles are aggressively territorial (Ref. 9626). Aggressive when breeding (Ref. 9710). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Taken incidentally in traps and small-meshed beach nets (Ref. 5217).
