American eel (Anguilla rostrata)
Eels spend most of their life in freshwater. They migrate to the sea to spawn. Adults spawn in Sargasso Sea. Their eggs drift in the current, larva hatch from the eggs and gradually develop into glass eels. The glass eels migrate to freshwater streams. Eels are thought to be the host fish for eastern elliptio (Elliptio complanata). Once the eel develops pigmentation it is called an elver. These elvers, or immature yellow eels, grow in freshwater for 8-23 years. When yellow eels mature, they change in shape and color and are labeled bronze or silver eels. They migrate to the ocean south of Bermuda to spawn and then scientists think that they die.
