Short description Bestämningsnycklar | Morfologi | Morfometri

Mjukstrålar i ryggfenan (totalt) : 11; Taggstrålar i analfenan: 4 - 5; Mjukstrålar i analfenan: 43 - 47; Ryggkotor: 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

Phylogenetic diversity index (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).

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

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (16 of 100).
