Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal spines: 4 - 5; Anal soft rays: 8 - 9. Distinguished from all other species of the genus Batasio, except Batasio merianiensis in having an adult coloration consisting of a dark oblique predorsal bar and a dark spot on the sides of the body below the middle of the adipose-fin base. Differs from Batasio merianiensis by having length of adipose-fin base 30.0-33.3% SL (vs. 22.2) and eye diameter 18.2-23.5% SL (vs. 25.9) (Ref. 74340).

Occurs in rivers and streams with moderate to swift current and a predominantly rocky bottom; less often in slow-flowing streams with a muddy substrate. Hides among stones or submerged vegetation during the day and comes out at night to feed (Ref. 44354).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00955 (0.00534 - 0.01709), b=2.85 (2.70 - 3.00), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.1 se; based on size and trophs of closest relatives

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