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).
西大西洋: 佛羅里達 (美國) ,墨西哥灣與加勒比海到巴西。

生物学特性     字汇 (例如 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).

栖息于岸边与外海的珊瑚礁。 成鱼主要捕食水底的藻类也捕食海绵,海鞘类与卷曲异辐海葵而稚鱼吃像哲水蚤与纽虫的无脊椎动物.(参考文献 9626) 时常独居性的.(参考文献 9626) 稚鱼侵略性具有领域性。 (参考文献 9626) 侵略性当繁殖的时候.(参考文献 9710) 在鱼笼与小网目的海滩网中附带地捕获了。 (参考文献 5217)
