An eel
Eels belong to the Anguilliformes family.
An eel looks like a worm. It can be black or brown and sometimes they have spots on them. It has two eyes and sharp teeth.
Eels are found in most places around the world in rivers and lakes. In New Zealand eels travel to Tonga and lay their eggs there and when the baby eels are born they travel to New Zealand to find their parents.
Eels can swim fast and they eat bread, seaweed but can’t eat big fish. They also have very good night vision.
