Morphology | Morphometrics
Vertebrae: 39 - 41. Can be differentiated by a combination of the following characters: well defined straight vertical bars along the side of body, longer than those of Pseudoplatystoma fasciatum and Pseudoplatystoma punctifer; bars connecting to, or extending to, the dorsal region and continuing onto other side of body; vertical bars of anterior region straight and extending below dorsolateral dusky area; usually no spots below lateral line, some individuals with two or three spots; 39-41 vertebrae (Ref. 59362).
