Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Radios blandos dorsales (total) : 22 - 27; Espinas anales: 0; Radios blandos anales: 37 - 43. The head, some parts of the body and the end of the dorsal and anal fins are darker in coloration. The whole body is generally brown. Dorsal fin origin behind anal fin origin, dorsal base/anal base rates = 0.5-0.6. LS/body depth ratio = 3.5-4.5. Long caudal peduncle, length/depth ratio = 2.9-5.5.

Affinities: close to M. mento and M. furcidens.

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=0.01380 (0.00615 - 0.03096), b=2.86 (2.69 - 3.03), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 2.5 ±0.28 se; based on food items.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (14 of 100).
