known for
what they eat. They feed on the blood of cattle, horses, other animals, and
sometimes even people. Vampire bats can be dangerous because they can spread a
disease called rabies, which can be deadly to those infected. To get to the
blood of their animal victims, they bite away any fur or feathers, and then
bite. They drink only small amounts of blood each time they feed. Vampire
Bat, a bat that feeds on fresh blood. A number of large, fruit-eating bats are
miscalled vampire bats. True vampire bats have upper incisor teeth shaped like
canines. There are three species, found in various areas of Latin America.
Vampire
bats have no tails and are about three inches (7.5 cm) long. They shelter in
areas of almost complete darkness, such as eaves and hollow trees. To obtain
their food, they will attack almost any warm-blooded animal that is resting
quietly. After biting a victim, they suck the flowing blood. Although the wound
and amount of blood lost are not serious, these bats are dangerous because they
can transmit such diseases as rabies
Does a Vampire Bat Kill Its
Prey? Vampire bats are very
small mammals. They usually weigh about 1 ounce (28 grams). Their wingspan
might measure 12 inches (30.5 centimeters) across. They eat only about 1
tablespoon (15 milliliters) of blood a day. Most animals never notice that
they’ve been bitten by a vampire bat. The greater danger, though, is
that vampire bats often spread diseases to their victims. If a vampire bat
drinks the blood of an animal that has a disease, the bat can then carry the
germs of that disease and spread them to other animals it bites. Sometimes the
bat itself can become sick, as well.
Common
vampire bats, which live in Mexico and South America, feed on the blood of
horses, cattle, and fowl (birds such as chickens). Although it is rare, vampire
bats can also feed on human blood.
A
vampire bat searches for a sleeping animal. Then it lands nearby and climbs
onto the animal. The bat uses its teeth to cut away the fur of the animal and
quickly makes a small cut into the victim’s skin. Its teeth are so sharp that
the sleeping animal doesn’t even feel the cut.
Once an
animal starts bleeding, the vampire bat uses its tongue to lap up blood from
the wound.

Vampire Bats are small
flying mammals. They give birth to live young and nourish them with milk. They
are nocturnal; they are most active at night and sleep during the day hanging
upside-down. Vampire Bats live in Central and South America. Vampire Bats are microchiropterans, bats who use echolocation.
Anatomy: Bats' wings are long fingers covered by thin
skin, and they have furry bodies. These tailless mammals have weak legs and
don't walk very well. Vampire Bats have a wingspan of only 8 inches (20 cm).
The body is the size of a person's thumb.
Senses/Diet: Vampire Bats can see, but use echolocation as
their primary sense in order to find insects and small animals to eat. While
flying, these bats send out high-pitched sounds that bounce off other objects.
The bat listens for the bounced sound, and can determine where objects are
located. People cannot hear these high-pitched sounds. The vampire bat is the
only bat (and the only mammal) that eats blood, preying on cattle, horses,
large birds and pigs. Vampire bats don't suck animals' blood, they make a small
hole with their two very sharp incisor teeth and lap up the blood, which
doesn't clot (thicken) because of anti-coagulants (anti-thickeners) in the
bat's saliva.
