Opistognathidae (Jawfishes)
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..

背棘 (总数) : 11; 背的软条 (总数) : 13; 臀棘: 2; 臀鳍软条: 12; 脊椎骨: 26. This species is distinguished by the following characters: with a rigid upper jaw lacking flexible lamina posteriorly, extending about 0.7 to 0.9 eye diameters behind posterior margin of orbit; infraorbitals are very slender and tubular, the third infraorbital very elongate with large suborbital shelf; D XI,13; A II,12; vertebrae 10+16; scales on the belly minute and distinctly embedded; body with about 80-99 scale rows in horizontal series; vomerine teeth 1-3. Colouration: opercle with a conspicuous dark spot; color of sides and anal blue with large yellow spots (Ref. 128653).
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).
