Dicas de identificação

1. 1

   Spot Pattern

   Look for the characteristic large, irregular dark spots or blotches covering the entire body, including the head and fins. This distinguishes it from other Pseudoplatystoma species with stripes or fewer, smaller spots.

2. 2

   Head Shape and Barbels

   Note the long, flattened head and the very long maxillary barbels that extend well past the pectoral fins. The mouth is broad.

3. 3

   Fin Spines

   Feel for the strong, serrated spines in the dorsal and pectoral fins. These are a key defensive feature.

4. 4

   Body Proportions

   Observe the elongated, somewhat cylindrical body shape, typical of large predatory catfish.
