Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais (total) : 37 - 43; Espinhos anais: 0; Raios anais : 32 - 39; Vértebras: 77 - 85. Most similar to P. guianensis from which it differs most markedly in higher numbers of dorsal and anal fin rays, vertebrae, and predorsal scales. Predorsal scales 109-143, mean 130.5.
Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205).
