The sea lamprey is a jawless cartilaginous fish with a suction-cup mouth ringed with sharp teeth. It's parasitic, surviving on the blood of its prey. The invasive species was introduced to the Great Lakes in the early 20th century via man-made canals & has become a major pest. pic.twitter.com/KdKuiXaWOX

Lampreys suck!⁰

Actually, this lamprey is crucial to the river ecosystem. And dare we say it, quite adorable 😆

Lamprey need clean water for spawning, so protecting their freshwater wetland habitat is key to their survival. #Springwatch @BBCSpringwatch pic.twitter.com/G5ztQqN1kB

That feeling when you fall asleep with your mouth open.

Sea lamprey feed on fish body fluids by using their drill-like tongues to rasp through scales and skin. To sweeten the deal, they secrete an enzyme that prevents blood from clotting.
