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).

Descrição breve
Morfologia | Morfometria
Espinhos dorsais (total): 11; Raios dorsais moles (total): 14; Espinhos anais 2-3; Raios anais moles: 12 - 13; Vértebras: 27. This species is distinguished by the following set of characters: anterior nostril is a short tube with simple cirrus on posterior rim; maxilla rigid, not produced as a thin flexible lamina posteriorly; no supramaxilla; subopercle without a broad, fan-like flap; vomer no teeth; body with 43-47 oblique body scale rows in longitudinal series; vertebrae 10 + 17 = 27. Colouration: sides with two rows of pale spots, each approximately diameter of eye; body with six vertically irregular, evenly spaced bands, widest on mid-side, and two rows of six pale spots, each spot approximately diameter of eye; buccal area surrounding esophageal opening is pale. Also easily disinguished from its congeners by the divergence in the mitochondrial gene COI, as specimens form a monophyletic group that differs from its closest relative (O. whitehursti) by an
average of 11% (654 bp analyzed) (Ref. 129348).
This species is common in coastal regions, in depths associated with gravel-sand bottoms, near coral reefs and rocky areas. Feeds mainly on small benthic organisms near the bottom (e.g., small shrimps, crabs, and isopods) (Ref. 129348).
