Description

The Arctic lamprey is a lamprey (Petromyzontidae) from the northern hemisphere. The species is a primitive, jawless fish with an eel-shaped, scaleless body and a round sucking mouth full of horny teeth. It is anadromous: adults live parasitically in coastal and estuarine waters, where they attach to fishes and take flesh and body fluids with their rasping mouth, and migrate into rivers and lakes to spawn. The worm-like larvae filter detritus and algae in the sediment for years. The species is harmless to humans.
