Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 2; Dorsal soft rays (total): 6; Anal spines: 0; Anal soft rays: 12; Vertebrae: 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).
