Description

Brachyhypopomus beebei is a weakly electric knifefish of the family Hypopomidae in South America. The species has an elongate, laterally compressed body without a dorsal fin, with a long anal fin that lets it swim smoothly forwards and backwards. A weak electric organ in the tail aids orientation and communication in turbid water. The fish often stays among floating vegetation and hunts at night for aquatic insect larvae and small invertebrates. Reports state the species can reach about 35 cm. It is caught locally for food.
