Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 10 - 12; Mjukstrålar i ryggfenan (totalt) : 14 - 17; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 17 - 20. Interorbital space narrow and concave, its width about 1/2 of eye diameter, and covered with bony plates (Ref. 559).
Body shape (shape guide): fusiform / normal.
Deep records for this species is anomalous and must be regarded as questionable (Ref. 6793).
