Teleostei (teleosts) > Ovalentaria/misc (Various families in series Ovalentaria) > 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).

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; demersal; depth range 92 - 100 m (Ref. 26893). Subtropical

Estimates based on models

Preferred temperature (Ref. 115969): 21.5 - 25.8, mean 23.2 (based on 5 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.6 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
