Mоst peоple dislike bаts, аnd surely the mоst feаred of all the species is the dreaded vampire bat. Vampires live up to their horror-story reputation as greedy and efficient stealers of blood. Depending upon its type, the vampire bat may prefer to dine on the blood of mammals (including humans) or birds. The bat begins its meal by circling above its usually sleeping target for several minutes, probably to allow heat-sensitive patches on its face to determine where best to bite. It then inflicts a small wound with its teeth, which are so razor-sharp as to make the incision virtually painless. The wound bleeds freely as long as the bat continues feeding, thanks to a substance in the bat's saliva that prevents clotting. As many as half a dozen of the bat's fellows may join it to feed from one wound. Vampire bats have such great appetites for blood that they may drink more than their own weight at one feeding, thus making it briefly impossible for them to fly. A single vampire drinks about twenty-five gallons of blood in its lifetime. Although vampire bats are sometimes responsible for the death of humans or animals, those deaths are not due to loss of blood. Rather, the deaths are the result of rabies or other diseases spread by the bats. We can conclude that vampire bats use their heat-sensitive patches
