Short description Morphology | Morphometrics

The species is closely related to Metynnis hypsauchen (Müller & Troschel, 1844) according to 1. high number of gill-rakers, 2. long adipose fin, 3. deep body, 4. short head and 5. long occipitale and is clearly defined because of 1. the high number of serrae (36-37 vs. 27-32 of M. hypsauchen), 2. the small scales (91-93 vs. about 75-83), 3. uniformly silver colouration and 4. the extremely elongated dorsal fin and anal fin (Ref. 79633).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02884 (0.01251 - 0.06647), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±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.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
