>>The lamprey eel, also known as the sea lamprey, is a primitive, eel-like fish that invaded the Great Lakes in the early 20th century through shipping canals.2 They have an eel-like body with two close dorsal fins, seven gill openings, and a large round mouth with sharp, curved teeth and rasping tongue.1 The adult lamprey may be characterized by a toothed, funnel-like sucking mouth.0 Despite their similar body shape, the lamprey and eel are not even closely related, with lampreys being more closely related to hagfish and sharks. Quite similar indeed
