The Electric Eel
The Electric Eels are electric fish and the only species in that genus. Despite the name, they are not an eel but rather a knifefish. They are also known for its unusual breeding behavior where during dry season, the make eel makes a nest from its saliva into which the female lays her eggs. As many as 3000 young hatch from the eggs in one nest. The male electric eels are much smaller than the female eels. They inhabit fresh waters of the Amazon and Orinoco River basins in South America, in floodplains, swamps, creeks, small rivers and coastal plains. They often live on muddy bottoms in calm or stagnant waters. They feed on invertebrates, although adult eel may also consume fish and small mammals.
