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);  eximius: Name from Latin 'eximius' meaning select, distinguished, uncommon, it was incorrectly stated in the original description to mean “beautiful,” but certainly it is an appropriate adjective for this species..

Biologia     Glossário (p.ex. epibenthic)

Occur over sand bottom of the continental shelf (Ref. 75154). Mouthbrooders (Ref. 240). Eggs which are clumped together in a sticky egg ball inside the parent's mouth are sometimes released in a burrow during brief feeding periods (Ref. 40511).

Estimates based on models

Índice de diversidade filogenética (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.7   ±0.6 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (25 of 100).
