FBname: Porthole shovelnose catfish
Comments: Rather rare, confined to the deeper and slow-moving parts of large rivers together with some <i>Loricaria</i> and <i>Potamotrygon</i>.  Its body shape and color pattern are perfectly adapted to the muddy bottom where they stay (Ref. 35381).  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 (Ref. 35381).
