Dorsale zachte stralen (totaal) : 7; Anale zachte stralen: 12 - 13; Wervels: 40 - 41. Distinguished from its congeners, except Batasio batasio, in possessing a color pattern on the body consisting solely of horizontal stripes (vs. with vertical bars and spots, or a uniform dark brown color).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00408 - 0.01859), b=2.94 (2.76 - 3.12), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.3   ±0.1 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
