The sea lamprey (Petromyzon marinus) is a parasitic lamprey found in the northern Atlantic Ocean along shores of Antarctica and North America, in the western Mediterranean Sea, and in the shores of the Great Lakes. The lamprey uses its suction cup-like mouth to attach itself to the skin of a fish and rasps away tissue with its sharp tongue and keratinized teeth. Secretions in the lamprey’s mouth prevent the victim’s blood from clotting. Lampreys are considered a delicacy in some parts of Europe, including Southwestern France.
