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); thionyi: Named for our colleague and dear friend Thiony Simon (1985–2016), who passed away during preparation of this article..

簡単な記述
形態学 | 形態計測学
背面の脊椎 (合計): 11; 背鰭 (合計): 15-16; 肛門の骨 3; 臀鰭: 14 - 15; 脊つい: 28. This species is distinguished by the following set characters: anterior nostril is a short tube with simple cirrus on posterior rim; maxilla rigid, not produced as a thin flexible lamina posteriorly; no supramaxilla; subopercle with a broad, fan-like flap; vomer with one tooth; pale buccal area surrounding esophageal opening; body with 45-52 oblique body scale rows in longitudinal series; vertebrae 10 + 18; spinous dorsal fin with black blotch, when present, between spines 2-5. Colouration: body with five poorly defined irregular bands and sides sometimes with diagonal rows of pale spots smaller than eye diameter; when present, a black blotch in spinous dorsal fin between spines 2-5; buccal area surrounding esophageal opening pale. Also easily distinguished from its congeners by the divergence in the mitochondrial gene COI, as specimens form a monophyletic group that differs from its closest relative (O. maxillosus) by an average of 9% (654 bp analyzed) (Ref. 129348).
Found solitarily, always in small constructed burrows on sandy rubble bottoms. It feeds on small benthic organisms that live near the bottom (e.g., small shrimps) (Ref. 128653).
