Porthole shovelnose catfish (Hemisorubim platyrhynchos) fish species information

Scientific Name
Hemisorubim platyrhynchos

Common Name
Porthole shovelnose catfish

Biology
Rather rare, confined to the deeper and slow-moving parts of large rivers together with some Loricaria and Potamotrygon. 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).
