Length at first maturity / Size / Weight / Age

Maturity: L_m ?, range 7 - ? cm
Max length : 14.5 cm SL male/unsexed; (Ref. 5316)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 32-42; Anal soft rays: 3 - 4. Body rings: Trunk 16; tail 30-31 (Ref. 6820).

Majority of collections are from freshwater streams and rivers. Probably reaches 14.5 cm SL. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

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=0.00087 (0.00033 - 0.00230), b=3.03 (2.81 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.4 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.).

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