(Perch-likes) > Pomacanthidae
Etymology: Holacanthus: Greek, holos = full + Greek, akantha = thorn (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; non-migratory; depth range 1 - 70 m (Ref. 9710). Subtropical, preferred ?; 32°N - 8°N, 98°W - 57°W (Ref. 55265)
Western Atlantic: Florida, USA and Gulf of Mexico to Brazil. Eastern Central Atlantic: St. Paul's Rocks (Ref. 13121).
Length at first maturity / Size / Weight / Age
Maturity: Lm 22.0  range ? - ? cm
Max length : 45.0 cm TL male/unsexed; (Ref. 4858); common length : 30.0 cm TL male/unsexed; (Ref. 3797); max. published weight: 1.6 kg (Ref. 26340)
soft rays: 20 - 21. Tail and pectoral fins entirely yellow. Black spot on forehead has electric blue spots and is surrounded by narrow, electric blue ring. Large blue spot at base of pectoral fin (Ref. 26938). Adults develop short spines on the margin. The color of large adults is purplish blue with yellow-orange rims to the scales; head above eye dark blue, below greenish yellow; mouth, chin, throat, chest and abdomen purplish blue (Ref. 13442)
Found on coral reefs. Generally occurs solitarily or in pairs. Moves gracefully between seafans, seawhips, and corals (Ref. 9710). Stomach contents of 26 specimens indicate that the species feeds almost exclusively on sponges supplemented by small amounts of algae, tunicates, hydroids and bryozoans. Young pick ectoparasites from other fishes (Ref. 9710). Marketed fresh (Ref. 3797).
