Land lampreys can be found in all but the hottest and the coldest environments. They prefer the dark and dampness of the subterranean world and so are most often encountered there.
A land lamprey attacks by attaching to a victim and draining blood. An application of fire causes the land lamprey to releases its hold and move away from the source of the flame.
