The Common Vampire Bat (Desmodus rotundus) is a species of vampire bat. They have burnt amber colored fur on their backside while soft and velvety light brown fur covers their belly. They have large pointy ears and a flat leaf shaped nose. Their babies use tiny thumbs in the middle of the wing to cling on the mother s furry belly. The vampire bats have a wingspan of about eight inches and a body about the size of an adult's thumb. 3

Feeding If not for their diet, people would not pay much attention to these small bats. Vampire bats feed on the blood of large birds, cattle, horses, pigs, dogs and many other animals including humans. However, they don t suck the blood directly from their "victims", they let it flow from the wound first before sucking or lapping it up. The Common Vampire is a highly evolved bat. The front teeth, lips and tongue are highly specialized, with the former used to trim the surrounding fur of the host, meaning acting like scissors. 9

Then a piece of skin is removed by the razor sharp V shaped front teeth much like using a spoon to scoop ice cream out of a cup. During this process the animal's saliva, which contains an anticoagulant, is released and the resulting wound bleeds freely, enabling the vampire t feed, using its highly specialized lower lip and tongue. The grooves in the lower lip and underside of the tongue form a straw like structure enabling the bat to suck up the blood rather than lap it. 10

Behavior The Common Vampire is one of the few known bats capable of walking, jumping and hopping. This is accomplished by folding its wings in such a fashion that the animal literally walks on its thumbs.this behavior is important because it permits the bat to stealth fully maneuver on the ground and host. Vampires choose hard to get to places on the host, such as shoulders, underside of the tail and teats and soft tissue near the hoof to get to the unique spot. 15

Often they will return night after night to the same animal (particularly tethered farm animals), so they just have to lift the scab from previous visits to get mor blood. It is speculated that before the introduction of domesticated animals, vampires fed upon a wide variety of animals including opossums, armadillos, raccoons, snakes, birds, monkeys, and so forth. 16

Paragraph 2 Interesting abilities and behaviours Topic sentence: One of the cool things about this bat is its wide variety of interesting abilities and behaviours. 3 Infant bats actually grab onto their mom s wings using tiny thumbs located on their wings. 4 When feeding they use their teeth, lips and tongue like a tiny pair of scissors to cut away fur from the surface of the wound. 5 Their saliva, or spit, actually keeps wound bleeding on their victims because it acts like an anticoagulant, which is something that kept wounds from healing themselves by clotting. 1 They have the ability to do move in many ways other than flying; in fact they can walk, jump and hop. 2 It can also move on the ground and on the bodies of the animals it feeds on.

One of the cool things about this bat is its wide variety of interesting abilities and behaviours. Firstly, they have the ability to move in many ways other than flying; in fact, they can walk, jump and hop. It can also move on the ground and on the bodies of the animals it feeds upon. When they are infants, the baby bats actually grab onto their mom s wings using tiny thumbs located on their own wings. When they feed, they use their teeth, lips and tongue like a tiny pair of razor sharp scissors to cut away fur from the surface of the wound. Then their saliva, or spit, actually keeps the wound bleeding on their victims, because it acts as an anticoagulant, which is something that keeps the wounds from naturally healing themselves through clotting. All of these fascinating abilities just add to the mystery and intrigue that surround this little animal. 29
