Identification Tips

1. 1

   Coloration and Pattern

   Look for the distinctive marbled or blotched pattern of dark brown/black on a lighter background, resembling a bumblebee. This is the most reliable visual identifier.

2. 2

   Barbels

   Observe the three pairs of long barbels, especially the maxillary barbels which extend significantly past the pectoral fins.

3. 3

   Body Shape and Size

   Note the robust, elongated body and broad head. Adults can reach impressive sizes, up to 60 cm (24 inches) standard length, with some reports of larger specimens.

4. 4

   Fin Spines

   The presence of strong, serrated spines in the dorsal and pectoral fins is characteristic of the family Pimelodidae and this species.
