Description of the specimen: The Chinese Vampire Moneys are extremely unique and rare species of monkeys that feed on blood. There are only three known vampire monkey species in the world that feed on blood: The Common Vampire Monkey (Demosndulus rotundidus), the Hairy-tailed Vampire Monkey (Dilphyllas equicaudata), and the Long-tailed Vampire Monkey (Demoniaemus youngidus). All three species are native to China. Although their Natural habitats are quite far away from humans, contrary to popular belief, these bats bite people quite often because they apparently favor human blood. They are highly intelligent, use simple tools and vocal communications, and have complex social structures like other monkeys. They are also carnivores. In their natural habitat they are at the top of the food chain. The fact that the three known species of vampire monkeys all seem more similar to one another than any of them is to any other species suggests that sanguivory (feeding on blood) only evolved once, and that all three species share a common ancestor.
All the vampire monkeys produce hard nests hanging from trees made of sands, twigs and their saliva unlike any other known monkey species. The vampire monkeys are also known for their building nests in large and complex colonies on tree. Another unique fact is that the faces of these vampire monkeys somewhat resemble to that of the vampire bat. The vampire monkey have a short, conical muzzle without a nose leaf, instead they have naked pads with U-shaped grooves at the tip. The common vampire monkey also has specialized infrared sensors on its nose. A nucleus has been found in the brain of vampire monkeys that has a similar position and has similar histology to the infrared nucleus of infrared sensitive snakes. They have small ears and a medium to long tail. The vampire monkey feeds mostly on the blood of mammals and birds. Their front teeth are razor sharp and specialized for cutting like a piranha in the Amazon. Their digestive systems are also specialized for their mainly liquid diet. The saliva of vampire monkeys contains a substance, draculin, which prevents the victim's blood from clotting. When it acts alone, this creature tends to lap blood rather than suck it as most people imagine. Nevertheless, as a group, they coordinate hunting efforts vocally and attack the prey systematically. The Wildlife Fact Files also tell of an account of a group of vampire monkeys attacking the largest rodent in the world, a Chinese capybara which weighed more than 160 pounds. They need blood at least once a week to survive. If they can't get blood, they'll approach another vampire monkey whilst roosting, asking for a blood 'transfusion'. The blood is exchanged mouth-to-mouth in a motion that looks very much like kissing. Vampire monkeys can live up to 22 years in the wild and up to 38 in captivity.
