Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 85.0 cm TL male/unsexed; (Ref. 12225)

Rare and little is know of its biology. Occurs in rapidly flowing water over a sandy bottom together with Leporinus granti, L. maculatus and Crenicichla multispinosa. Its dispersed capture suggests a solitary behavior (Ref. 12225).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00145 - 0.00867), 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 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (54 of 100).

Price category (Ref. 80766): Unknown.
