Etymology: Stegastes: Greek, stegastos, -e, -on = covered (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; non-migratory; depth range 1 - 15 m (Ref. 40395), usually 1 - 4 m (Ref. 9626). Tropical
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.6 cm TL male/unsexed; (Ref. 9626)
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).
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).
