2.  Scientific name: Electrophorus electricus  Kingdom: Animalia  Phylum: Chordata  Class: Osteichtyes  Evolved completely about 7 million years ago  Not actually eels, but knifefish

3.  Elongated, cylindrical body  2 meters long (6ft)  20 kg (45lbs)  Largest of the gymnotiformes

4.  Live in fresh water ◦ River floodplains, swamps creeks coastal plains  Often live in the muddy bottom of calm bodies of water and stagnant rivers.  Amazon and Orinoco Rivers

5.  Feed mostly on invertebrates  Adults may eat fish or small mammals  Hatchlings will eat younger embryos, eggs, shrimp, or small crabs

6.  The male eel makes a nest  The female lays eggs in it during the dry season  Up to 3000 eggs will hatch at one time

7.  Population: Unknown  They generate a shock of 500 watts (500 volts and 1 ampere) on average  They can shock up to 700 watts  Human beings die at as little as 0.75 ampere

8.  Can control the intensity of their shocks  Eels can be used to generate electricity for human purposes  In Japan, two eels in a tank were used to light up a Christmas tree  Eels are very hostile and will kill and animal it is with besides another of its own species
