Short description Claves de identificación | Morfología | Morfometría

Radios blandos dorsales (total) : 11; Espinas anales: 4 - 5; Radios blandos anales: 41 - 43; Vértebra: 37 - 40. This species is distinguished from R. molossus by having fewer branched anal-fin rays (41-43, versus 43-47). It differs from R. itupiranga by having more anal-fin rays (41-43, versus 38-41), fewer scale rows between lateral line and anal-fin origin (15-16, versus 18-19) and fewer scale rows around caudal peduncle(27-28, versus 30-31).

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=0.00468 (0.00178 - 0.01229), b=3.13 (2.90 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 4.1 ±0.7 se; based on size and trophs of closest relatives

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (13 of 100).
