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); 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.

Dorsale stekels (totaal) : 10 - 11; Dorsale zachte stralen (totaal) : 11 - 12; Anale stekels: 2; Anale zachte stralen: 10 - 11; Wervels: 26.

(Ref. 128653).
Body shape (shape guide): elongated; Cross section: compressed.
