Likely COMMON VAMPIRE BAT (Desmodus rotundus) - ©Bruce Dale A vampire bat laps blood from a sleeping calf somewhere in the United States. These archetypal eerie animals are the only mammals that subsist solely on blood. Vampire bats are very agile and a recent study found that common vampire bats can, in addition to walk, run at speeds of up to 7.9 km per hour (4.9 miles per hour). They locate a suitable place to bite using their infrared sensors. Vampire bats tend to live in colonies in almost completely dark places, such as caves, old wells, hollow trees, and buildings. They range in Central to South America and live in arid to humid, tropical and sub tropical areas. Colonies can range from a single individual to thousands, often roosting with other species of bat. Each colony will typically have only one reproducing male, with around twenty females and their offspring. Each individual needs a blood meal at least once every few days. If a bat fails to get adequate food during its foraging, it may contact another vampire bat in its colony to induce a food donation. The food exchange occurs mouth-to-mouth in an activity similar to kissing. Vampire bats can live up to nine years in the wild and up to 19 in captivity. If there is fur on the skin of the host, the common vampire bat uses its canine and cheek teeth like a barber’s blades to shave away the hairs. The bat’s razor-sharp upper incisor teeth then make a 7mm long and 8mm deep cut. The upper incisors lack enamel, which keeps them permanently razor sharp. The bat’s saliva, which is injected into the victim, has a key function in feeding from the wound. The saliva contains several compounds that prolong bleeding, such as anticoagulants that inhibit blood clotting, and compounds that prevent the constriction of blood vessels near the wound.
