Short description Claves de identificación | Morfología | Morfometría

Espinas anales: 0; Radios blandos anales: 18 - 21. Diagnosis: flanks with intense pigment band from a vertical through anal fin origin and extending caudad to posterior margin of median caudal fin rays; 26-28 scales in longitudinal series; adipose fin not broad and rounded, its total length less than 3x its length at base (Ref. 80290).

Maximum size 70 mm SL (Ref. 80290). Affinities: very similar to P. major and the justification for maintaining separate species status is questionable (Ref. 80290). More details on the differences between P. urotaenia and P. major can be found in Ref. 80290.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00484 - 0.02371), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.1 ±0.3 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 (10 of 100).
