Moray, American and electric eels live in freshwater streams, ponds, deep tropical and sub-tropical waters. Their habitats stretch from Greenland to South America's Orinoco basins.
Despite being commonly referred to as eels, electric eels are actually a type of fish that closely resembles the carp family. Their bodies have special cells called electrolytes that store power and deliver a jolting shock when they are threatened.
There are almost 200 different species of Moray eels. They are carnivorous and spend most of their time lying in wait for prey in coral reefs.
American eels dwell mostly in freshwater and marine habitats. It is possible they will be listed as an endangered species due to large population declines.
