Actinopterygii (ray-finned fishes) > Perciformes
(Perch-likes) > Chaetodontidae
Etymology: Prognathodes: Greek, pro = first, in front of + Greek, gnathos = jaw (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; non-migratory; depth range 1 - 90 m (Ref. 47838), usually 12 - 90 m (Ref. 47838). Tropical
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm TL male/unsexed; (Ref. 47838)
(total): 13 - 14;
soft rays: 14 - 16. Upper half of body yellow-orange, shading into blackish basally in dorsal fin; lower half of body white; orange bands on head and a narrow orange bar on caudal peduncle (Ref. 13442).
Western Atlantic: southern Florida and the western Gulf of Mexico to the West Indies-Caribbean region and Venezuela.
Inhabit deep coral-rich reefs and drop-offs (Ref. 47838). Feed on small invertebrates. Often seen nibbling on the tube feet of sea urchins or the tentacles of tubeworms (Ref. 9710). Unlike some chaetodonts it does not pick parasites from the bodies of other fishes (Ref. 5521). Solitary, sometimes in pairs (Ref. 47838). Seek refuge when approached (Ref. 47838). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
