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); vigilax: Name 'vigilax' from the Latin genitive adjective meaning 'watchful', in allusion to the day-time behavior of the species in the genus in maintaining an almost continuous lookout for potential food organisms passing in close vicinity of their burrows.

背棘 (總數) : 10 - 11; 背的軟條 (總數) : 11 - 12; 臀棘: 2; 臀鰭軟條: 10 - 11; 脊椎骨: 26.
