Etymology: Trigonognathus: Greek, trigono = a triangle + Greek, gnathos = jaw (Ref. 45335). Refers to the triangular shape of the jaws (Ref. 31259); kabeyai: Named after Mr. Hiromichi Kabeya who collected the type specimens (Ref. 31259).
Eponymy: Hiromichi Kabeya was captain of the trawler ‘Seiryo-Maru’ from which the holotype was caught (1986). He was still master of the vessel in 2006. (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 10.4 - 16.3, mean 11.4 °C (based on 5 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00188 - 0.00734), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.4 se; based on diet studies.

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100).
