Dorsale stekels (totaal) : 2; Dorsale zachte stralen (totaal) : 6; Anale stekels: 0; Anale zachte stralen: 12; Wervels: 46. Diagnosis: Gogo brevibarbis is distinguished from other members of Anchariidae in having bicuspid teeth on the upper and lower jaws vs. unicuspid (Ref. 56142). It can be further distinguished from Gogo arcuatus in having a straight dorsoposterior margin of the dorsal fin vs. concave; and from G. ornatus in having a larger eye, 15.9% of head length vs. 9.2-13.6% (Ref. 56142).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5781 [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).

Trofisch niveau (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

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