There is a rumor circulating around the web about a species of monkey that subsists solely on the blood of humans. The tiny monkey has been dubbed the “vampire monkey“. Noone has been able to determine for certain as to it’s true existence as there is very little information on the supposed species, leading many to believe that it is in fact not a real animal, just a made-up creature.
As far as the vampire monkey, I do not have any further information to provide you as to its true existence or not. That does not mean however that it is impossible for the vampire monkey to exist. In fact, there are a few real animals that humans know for a fact do exist and drink the blood of animals (and humans if they were given a chance). Because they subsist on blood, many humans relate them very closely with human vampires, and indeed all have the “vampire” name in their title.
One of these animals is the vampire finch. Unlike the vampire monkey, the vampire finch is a real creature that is known to exist. It is a small black endangered bird native to the Galapagos Islands that uses its beak to peck at other birds until it draws blood. It then drinks the other bird’s blood as food.
Another is the vampire bat. The vampire bat, like most other bats, hunts at night. Unlike many bats who eat off berries and insects however, the vampire bat feeds off the blood of animals – depending on the species they prefer large mammals or small birds. Feeding sessions typically last about 20 minutes, and involve the vampire bat using its teeth to bite it’s victim. The saliva has an anticoagulant which prevents the blood from clotting, keeping it flowing so that the vampire bat can feed in comfort.
Another animal that feeds off blood is the candiru fish. The candiru fish is a small translucent fish native to the Amazon. The candiru fish is famous for the story of how it supposedly entered the urethra of a human that was urinating in the river. The fish is a vampiric parasite that feeds on blood.
