Out of the 1200 species of bats, only three actually feed on blood (the common vampire bat, the hairy-legged vampire bat, and the white-winged vampire bat). The vampire bat lineage diverged from its family 26 million years ago. They are open to domestication and could also turn playful around humans. [41] Its stool is roughly the same as that from bats eating fruits or insects. A study in the January 10, 2003, issue of Stroke: Journal of the American Heart Association tested a genetically engineered drug called desmoteplase, which uses the anticoagulant properties of the saliva of Desmodus rotundus, and was shown to increase blood flow in stroke patients. The vampire bat has a heat-sensitive nose to detect its blood meal and will approach its prey from the ground. [28] These findings contradict the harassment hypothesis—which claims that individuals share food in order to limit harassment by begging individuals. Three extant bat species feed solely on blood: the common vampire bat (Desmodus rotundus), the hairy-legged vampire bat (Diphylla ecaudata), and the white-winged vampire bat (Diaemus youngi). [35] Their teeth are so sharp, even handling their skulls in a museum can result in cuts.[36]. Carnivorous Bats Apart from above mentioned bats, there is a small group of bats that rely on vertebrates for their primary feed. Because the hairy-legged vampire bat feeds on bird blood and it is the ancestral vampire bat, it is considered likely that the first vampire bats fed on bird blood as well. This substance ensures the blood from their prey doesn’t end up clotting in the body of the Vampire Bat. They are able to use receptors from the nose to help them find food. Vampire bats need special facial nerves that can sense the heat of their victims' veins, as well as those sharp teeth to access them while doing minimal damage to their host's skin. They have infared sensors on their nose which helps them to locate … N.p., n.d. They live in areas where there is plenty of food. Washington D.C.: Smithsonian Inst. Vampire Bats!

There are nearly 1,000 species of bats all having similar characteristics that make them unique, such as being the only mammal with the ability to fly. These splicing events occur exclusively in trigeminal ganglia, and not in dorsal root ganglia, thereby maintaining a role for TRPV1 as a detector of noxious heat in somatic afferents. The basic social structure of roosting bats is made of female groups and their offspring, a few adult males, known as "resident males", and a separate group of males, known as "nonresident males". Unfortunately, though the extraction of blood is not dangerous, the secondary infections created by the open wound can be.

Harpy Eagles feed primarily on animals that live in the trees, like sloths, monkeys, opossums, and some reptiles and birds. Its saliva prevents the blood from clotting.
