Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 9; Anal soft rays: 28 - 40; Vertebrae: 27. This species is distinguished from all its congeners by the following characters: predorsal scales 11-17 (vs. 7-9); differs from T. anostomus, T. denticulatus, T. kuluene, T. juruena by the principal teeth in dentary 4 (vs. 5-6), and larger and more robust teeth (vs. thinner and sharper); differs from T. anostomus, T. araguaiensis by the number of gill-rakers on the upper limb of the first gill arch 12-15 (vs.17-20); differs from T. anostomus by having a terminal mouth (vs. subsuperior mouth); differs from T. ommatus the maxillary teeth 1-4 (vs. 7-8) and by the presence of a conspicuous dark mark on the caudal peduncle (vs. inconspicuous mark limited to the posterior portion of the caudal peduncle); differs from T. carvalhoi by having a rounded dark mark on the caudal peduncle (vs. lozenge-shaped dark mark on the caudal peduncle); differs from T. rarus by the absence of dark longitudinal stripes on the trunk (vs. presence of such stripes); differs from T. rarus, T. georgiae having the scale rows between lateral line and pelvic-fin origin 3.5 (vs. 4.5-5.5); differs from T. denticulatus by having humeral marks separated by one or two vertical rows of scales (vs. humeral marks separated by three vertical scale rows) (Ref. 124043).

Consumed locally for recovery or during illness. Carnivorous (Ref. 42843).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02188 (0.00852 - 0.05619), b=3.00 (2.78 - 3.22), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±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).

Price category (Ref. 80766): Unknown.
