Zoology: Bones

Common vampire bats are small to medium sized bats, 2.5 to 3.5 inches in length with a wingspan of about 8 inches. Weighing between 1 to 2 ounces, they can consume 60% of their body weight in blood. Vampire bats have strong, well-developed hind legs, which affords them speed and agility on the ground. Their canine teeth are adapted for cutting hair and their large triangular incisors are highly modified to serve as sharp lancets to get the blood meal flowing freely. Their grooved and hairless nose contains infrared heat sensors to help them locate areas of rich blood flow closest to the skin surface of their victims. They have anticoagulant-rich saliva and a long, grooved tongue to aid their efforts. They only range in tropical rainforests from Mexico to Argentina and Chile and are also found on the islands of Trinidad and Margarita off the Venezuelan coast.
