The American eel is the only species in the Gulf of Maine that spends most of its life in freshwater but spawns in the Sargasso Sea, a large area of the Atlantic Ocean south of Bermuda and east of the Bahamas. American eel larvae (known as leptocephali) are transported by ocean currents for nearly a year until they reach the east coast of North America.
