The lamprey uses its suction cup-like mouth to attach itself to the skin of a fish and rasps away tissue with its sharp, probing tongue and keratinized teeth. A fluid produced in the lamprey's mouth, called lamphredin, [12] prevents the victim's blood from clotting. Victims typically die from excessive blood loss or infection.

When the lamprey has hatched from its egg into the larvae stage, it is limited to pools or backwater areas with a sand or sandy mud bottom. [5] The young lampreys filter feed for food for around five to seven years until they are large enough to attach themselves to a host ...
