Teeth names are created by a combination of 4 different characteristics: 1  The jaw where they are located: upper and lower (alternatively the terms maxillary and mandibular can be used) 2  The side of the face: left and right.  The type of tooth: incisor, canine, premolar, and molar.
Vampire bats are members of the New World Leaf-nosed bats, the Phyllostomidae. All three species of living vampire bats occur in South and Central America. Fossils of three other species reveal that several thousand years ago vampire bats were more widespread.
Once the common vampire bat locates a host, usually a sleeping mammal, they land and approach it on the ground. A recent study found that common vampire bats can, in addition to walking, run at speeds of up to 1.2 metres per second. Vampire bats locate a suitable place to bite their victims using their infrared sensors.
