Etymology: Opistognathus: Greek, opisthe = behind + Greek, gnathos = jaw (Ref. 45335); to the very elongate upper jaw of the type species of the genus, Opistognathus nigromarginatus (Ref. 128653).

Environnement : milieu / zone climatique / profondeur / gamme de distribution
Écologie
marin récifal; non migrateur (Ref. 52884); profondeur 0 - 44 m (Ref. 26893). Tropical
Western Atlantic: southern Florida, USA and Bahamas to northern South America. Including Antilles but absent in Jamaica (Ref. 26938).
Taille / Poids / Âge
Maturité: Lm ?  range ? - ? cm
Max length : 20.0 cm TL mâle / non sexé; (Ref. 7251)
Épines dorsales (Total) : 11; Rayons mous dorsaux (Total) : 16 - 17; Épines anales: 3; Rayons mous anaux: 14 - 16. Black spot on upper half of dorsal fin from sixth or seventh to ninth spines. Males have long, upcurved extension of maxillary bone marked with black bands (Ref. 26938). Females appear to lack the long double-banded maxilla, and there is only a single blackish band at the corner of the mouth (Ref. 13442).
Body shape (shape guide): elongated.
Inhabits sandy bottoms near coral reefs (Ref. 9710). Feeds on gastropods, crabs and fishes (Ref. 13628). Oviparous, mouthbrooding by males (Ref. 205). Monogamous and always in home-ranging pairs, that is they do not defend an exclusive territory (Ref. 52884).
Cycle de vie et comportement reproducteur
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
Displays facultative monogamy where males are constrained to mate with a single female due to resource limitation (Ref. 52884). Males incubate the eggs in the mouth (Ref. 205).
