Rare blood-sucking sea creature with rows of teeth found on Netherlands beach
A rare blood-sucking sea creature known as sea lamprey has been found on a beach in the Netherlands. "Sea lampreys do not have a jaw, but instead have a sucker-shaped mouth with teeth in it. They attack fish to suck the blood out. Sea lampreys belong to the oldest group of vertebrates, the Agnatha," a museum in the Netherlands said.
