Relevant Information:

Description: 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. Habitat: Rather rare, and is 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. Colouration: 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. Diet: 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.
