Petromyzon marinus

Lampreys are among the oldest fishes on earth. These long, eel-shaped fishes survive by feeding off the blood of other fishes. They have mouths like suction cups, which they use to attach themselves to other fishes. With the teeth on their tongues, they scrape a hole in their victim's skin and feed. Sea Lampreys live in salt water but spawn in freshwater streams where they build nests of pebbles. After spawning, the adults die. The young lampreys swim downstream and bury themselves in the mud, where they live for several years. As they transform into adults, they develop eyes and teeth and become parasites.
