Description

Hypopomus artedi is a weakly electric knifefish of the family Hypopomidae in northern 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. It generates a weak electric field to orient itself in the dark and detect prey. The fish inhabits creeks with fast-flowing water over a sandy bottom and hunts at night for aquatic insect larvae and small invertebrates. According to some sources the species can reach about 50 cm. It is eaten locally.
