Short description Identification keys | Morphology | Morphometrics

Anal soft rays: 132 - 164; Vertebrae: 70 - 82. Can be distinguished by having the following characters: seven to eight dark and clear alternating wide vertical bands on body; a foramen in the scapula; 14-15 precaudal vertebrae; 132-164 anal-fin rays (vs. more than 160 in all known Sternopygids); snout short (less than one third heald length); and mouth subterminal (Ref. 86967).

Caught with Anostomus brevior and Cynopotamus essequibensis (Ref. 86967).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (12 of 100).
