Western Atlantic: Brazil. Some authors consider the population in Caribbean Sea as another species, Pomacentrus dorsopunicans (Ref. 9626). Reported in the eastern Atlantic off Senegal (Ref. 10797).
西大西洋: 巴西。 一些作家在加勒比海考慮族群如另外種， 巴哈馬雀鯛〔Pomacentrus dorsopunicans〕 。 (參考文獻 9626) 已知在東大西洋塞內加爾外海中存在.(參考文獻 10797)
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 7.0 range ? - ? cm
Max length : 12.6 cm TL 雄魚/尚未辨別雌雄; (Ref. 9626)
背棘 (總數) : 12; 背的軟條 (總數) : 15 - 16; 臀棘: 2; 臀鰭軟條: 13 - 14.
Adults inhabit shallow, coral or rocky bottoms and sometimes near the shore in areas with little visibility (Ref. 9626). Juveniles were collected from tide pools and on rocky Lithothamnion reefs; adults found up to 15 m depth (Ref. 40395). A diurnal species, adults feed on benthic algae, polychaetes and harpacticoid copepods (Ref. 9626); also consume hydroids and sponges and has been observed to feed on Abudefduf saxatilis eggs at night (Ref. 9626). 16:21 SL/TL (Ref. 9626). Oviparous, distinct pairing during breeding; eggs are demersal and adhere to the substrate; males guard and aerate the eggs (Ref. 205).
