Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 27 - 33; Spine anali: 0; Raggi anali molli: 24 - 29; Vertebre: 64 - 72. Most closely resembles P. guianensis from which it differs most markedly in lower numbers of dorsal and anal fin rays, vertebrae, and predorsal scales. Predorsal scales 77-113, mean 93.9.
Body shape (shape guide): elongated.

Biologia     Glossario (es. epibenthic)

Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Fonte Biblio. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00126 (0.00057 - 0.00279), b=3.11 (2.93 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Fonte Biblio. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
Resilienza (Fonte Biblio. 120179):  Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (18 of 100). 🛈
