Diet:
Eels are mainly carnivores and feed off smaller fish and invertebrates. Typically, small fish are their first choice of food but they will resort to feeding on invertebrates if they are particularly hungry. Their diets change through the course of their life as they grow larger and feed on larger prey.
Lifestyle:
In autumn, adult eels leave fresh water and swim from New Zealand to tropical seas somewhere in the South Pacific. The females release their eggs, the males fertilize them, and the adults die after spawning. The eggs hatch into larvae that float to the surface and drift back towards New Zealand. They may take about 17 months to arrive

They are not endangered.They live in shallow, muddy water and come to the surface every 10 minutes because they breathe atmospheric air. Electric eels have three sets of internal organs that produce electricity. The organs are made up of special cells called "electrolytes."
