The American eel, Anguilla rostrata, is a catadromous fish found on the eastern coast of North America. It has a snake-like body with a small sharp pointed head. It is brown on top and a tan-yellow color on the bottom. It has sharp pointed teeth but no pelvic fins. It is very similar to the European eel, but the two species differ in number of chromosomes and vertebrae.
Although many anglers are put off by the snake-like appearance of these catadromous fish, eels are in fact exceptionally good fish. They are usually caught by anglers fishing for something else. The world record weight for the American eel is 9.25 pounds.
