The Anguillidae are a family of ray-finned fish that contains the freshwater eels.Except from the genus Neoanguilla, with the only known species Neoanguilla nepalensis from Nepal, [5] all the extant species and six subspecies in this family are in the genus Anguilla, and are elongated fish of snake-like bodies, with long dorsal, caudal and anal fins forming a continuous fringe.
Because the eels are catadromous (living in fresh water but spawning in the sea), dams and other river obstructions can block their ability to reach inland feeding grounds. Since the 1970s, an increasing number of eel ladders have been constructed in North America and Europe to help the fish bypass obstructions.

[3] Lamprey is sometimes seen for the plural form. [4]
