生态学
海洋 礁区鱼类; 非迁移的; 深度上下限 0 - 30 m (Ref. 7247). 熱帶; 6°S - 30°S, 50°W - 31°W
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。

尾鳍些微地分岔, 有圆的叶。 深褐色或蓝色的上方,颜色变化成下面的黄色。 在侧边上的狭窄的，深色的，和斜垂直的线。 吻与前额有淡蓝色线。 在胸的叶腋中的小深色的斑点, 另一个在尾柄的顶端上。 (参考文献 26938)
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).
