Actinopteri (ray-finned fishes) > Acanthuriformes
(Surgeonfishes) > Pomacanthidae
Etymology: Holacanthus: Greek, holos = full + Greek, akantha = thorn (Ref. 45335). More on author: Bloch.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 3 - 92 m (Ref. 9710), usually 3 - 35 m (Ref. 40849). Tropical; 36°N - 7°S, 86°W - 34°W (Ref. 55266)
Western Atlantic: Georgia (USA), Bermuda, and northern Gulf of Mexico to Santa Catarina, Brazil (Ref. 57756).
Length at first maturity / Size / Weight / Age
Maturity: Lm 15.8  range ? - ? cm
Max length : 35.0 cm TL male/unsexed; (Ref. 3797); common length : 30.0 cm TL male/unsexed; (Ref. 3797)
soft rays: 18 - 20. Front of body yellow; remaining parts of body, dorsal fin, and front of anal fin black. Caudal fin entirely yellow (Ref. 26938). Front margin of anal fin and edge of gill cover orange; bright blue on upper and lower part of iris. The young of about an inch in length are entirely yellow except for a blue-edged black spot on the upper side of the body posterior to the midpoint; with growth the black spot soon expands to become the large black area covering most of the body and dorsal and anal fins (Ref. 13442).
Inhabits rock jetties, rocky reefs and rich coral areas. Juveniles often associated with fire corals (Ref. 9710). Feeds on tunicates, sponges, zoantharians and algae. Marketed fresh (Ref. 3797).
