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); nothus: From the Latin 'nothus' meaning false or counterfeit, alludes to the erroneous initial belief that the female holotype was the sexually dimorphic counterpart of O. melachasme males; noun in apposition (Ref. 26893).
