On average how much blood does a vampire bat drink per day?

Answer 1

There are many different types of bats, but there's only one type that drinks blood-the vampire bat. In fact, they are the only mammals that feed entirely on blood. Scientists say the first vampire bats were related to bats that gorged themselves on the parasites of prehistoric beasts. Vampire bats mainly drink the blood of cows, horses, pigs, and birds.

Answer 2

There aren't any bats that suck blood but vampire bats lick blood and rarely attacks humans.

Additional information from Wikipedia:

Vampire bats hunt only when it is fully dark. Like fruit-eating bats, and unlike insectivorous and fish-eating bats, they emit only low-energy sound pulses. The common vampire bat feeds mostly on the blood of mammals, whereas both the hairy-legged vampire bat and white-winged vampire bat feed on the blood of birds. Once the common vampire bat locates a host, such as a sleeping mammal, it lands and approaches it on the ground. These bats will even occasionally feed on humans. They 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."The most common species, the South American vampire (Desmodus) is not fastidious and will attack any warmblooded animal. The white-winged vampire (Diaemus) appears to have a special preference for birds and goats. In the laboratory it has been impossible to feed Diaemus on cattle blood."

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.
