Information: |
Head strongly depressed
and the jaw prominently inferior. Dorsal 1-6 rays, Pectoral 1-7;
Pelvics 6; Anal fin; 9. Maxillary barbells reach back to the adipose
fin. The occipital process is united to the nucal plate, and the
humeral process is small. Rather rare, confined to the deeper
and slow-moving parts of large rivers together with some Loricaria
and Potamotrygon. Its body shape and colour pattern are
perfectly adapted to the muddy bottom where they stay. Feeds on
benthic organisms and fish. The position of the eyes and the shape
of the mouth of this piscivorous fish give to its stalking mode
of hunting. Adults have a greyish colouration, with a series of
brown spots of which those on the flanks have a black center.
Juveniles are heavier spotted than the adults. |
