Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale zachte stralen (totaal) : 11; Anale stekels: 4 - 5; Anale zachte stralen: 43 - 47; Wervels: 40. Readily distinguished from the other two species of the genus by having more branched rays on the anal fin (43-47, versus 41-43 in R. ogilviei and 38-41 in R. itupiranga). Hooks are present on the anal fin of adult male specimens of R. itupiranga and in one adult male of R. ogilviei but have not been found in males of R. molossus of comparable sizes.

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00182 - 0.01257), b=3.13 (2.90 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  4.1   ±0.7 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
