Lampreys are scientifically important because they represent an ancient lineage of vertebrates and are studied to understand vertebrate evolution and development.

Lampreys (sometimes inaccurately called lamprey eels) are a group of jawless fish composing the order Petromyzontiformes , sole order in the class Petromyzontida. The adult lamprey is characterized by a toothed, funnel-like, sucking mouth. The common name "lamprey" is probably derived from Latin , which may mean "stone licker" ( "to lick" + "stone"), though the etymology is uncertain. "Lamprey" is sometimes seen for the plural form.
