Morphology | Morphometrics
soft rays: 7. Color pattern consists of many narrow dark horizontal lines on the sides (one per scale row), generally light brown bands alternating with dark brown midlateral stripes, and the caudal fin is always spotted, alternating white and brown bands. Distinguished from Belobranchus segura by the combination of the following characters: 27-35 scales in transverse forward series (vs. 22-28); 21-34 predorsal scales (vs. 16-23); 20-23 transverse back series (vs. 18-21); head length 29-36% of SL (vs. 26-31% of SL) and predorsal length 40-46% SL (vs. (38-42 % SL) (Ref. 91761).
Occurs in estuaries and coastal streams, usually over rocky or gravel bottoms.

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00436 - 0.02631), b=3.06 (2.85 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
