LIFE CYCLE:
American eels are born in the Sargasso Sea, southwest of Bermuda. They migrate through fresh water to the Great Lakes. When they reach maturity, eels return to the salt waters of their birthplace to reproduce.
Before spawning, eels take on a silvery colour. The fry are transparent and then turn yellow. Their colour changes with age. The eel will become male or female depending on environmental conditions, particularly water density. American eels die after spawning.
In salt or brackish water, eels grow faster than in fresh water.
