Wikipedia Abstract

The silver lamprey (Ichthyomyzon unicuspis) is a lamprey commonly found in the Northern and Central United States, as well as a large part of southern Canada. Its binomial name means "fish to suck" in Greek and "one point" in Latin. The silver lamprey is a member of the Class Agnatha, sometimes referred to as cyclostomes (round-mouths). Other common names include: Bloodsucker, Blue Lamprey, Hitch-hiker, Lamper, Lamprey Eel. The silver lamprey should not to be confused with the sea lamprey (Petromyzon marinus), which has caused considerable damage to native fish populations in the Great Lakes region.
