Opistognathidae (Jawfishes)
後頜魚科 (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.
