High Quality Content by WIKIPEDIA articles! The American eel, Anguilla rostrata, is a catadromous fish found on the eastern coast of North America. The American eel has a slender snakelike body that is covered with a mucous layer, which makes the eel appear to be naked and slimy despite the presence of minute scales. A long and dorsal fin runs from the middle of the back and is continuous with a similar ventral fin.
