Vampire Bat - 0 views

  • Myths and legends from all over the world portray bats as blood-sucking demons. Vampire bats really do exist, but only three species in Central and South America.
  • Vampire bats feed on the blood of large birds, cattle, horses, and pigs. However, they donÕt suck the blood of their "victims".
  • Using their sharp teeth, the bats make tiny cuts in the skin of a sleeping animal. The bats' saliva contains a chemical that keeps the blood from clotting. The bats then lap up the blood that oozes from the wound. Another chemical in their saliva numbs the animal's skin and keeps them from waking up.

  • Scientists have discovered that vampire bat saliva is better at keeping blood from clotting than any known medicine. Vampire bats may one day help prevent heart attacks and strokes.

Vampire bats recognise their prey's breathing ( Vampire bats the only mammals to feed ...) - 0 views

  • Vampire bats, the only mammals to feed exclusively on blood, including human blood, recognize their prey by the sound of its breathing.
  • Vampire bats feed on the same prey over several nights
  • bats use breathing sounds to identify their prey in the same way as humans use voice to recognise each other.

Bat World - 0 views

  • Bats are not flying mice; they are not even remotely related to rodents. Bats are such unique animals that scientists have placed them in a group all their own, called 'Chiroptera’, which means hand-wing. Bats are grouped with primates and lemurs in a grand order called Archonta.
  • Bats are not blind. Most bats can see as well as humans. Fruit bats have eyesight that is adapted to low-light, much like cats. Fruit bats also see in color.
  • If a bat swoops toward you, it’s probably after the mosquito that is hovering just above your head -  not your hair.

  • Not all bats are vampires.  Of the world’s 1100+ species, only three are vampire bats limited mostly to Latin America. Vampire bats are very small (about the size of a package of M&Ms). Vampire bats do not attack humans or suck our blood; they prefer to get their teaspoon-sized meals from other animals.
  • Bats are not ugly or dirty. Most bats have very cute faces, some even resemble deer, rabbits, and little Chihuahuas. Like cats, bats spend an enormous amount of time grooming their fur, keeping it soft and silky.
  • Bats are wild animals, and all wild animals can be dangerous. Additionally, grounded bats are more likely to be sick so they should never be rescued bare-handed.
  • Bats are shy, gentle, and intelligent. They are among the slowest reproducing animals on earth. Most bat species have only one live young per year.

Bats - 0 views

  • Bats often make people think of vampires, creatures of the night, and Halloween. Beyond the myth and folklore, bats are one of the most important groups of animals.
  • Bats are mammals that belong to the order Chiroptera (ky-rop-tera), which means, "winged hand". The wings or hands of a bat have very long finger bones covered by a strong skin. Bats are the only mammals that can fly. Like all mammals, they are "warm-blooded", have bodies covered with fur, and nurse their young (pups) with milk.
  • Nearly all bats are helpful animals. In fact, tropical rainforests could not survive without bats. Bats are responsible for controlling pest insect populations, pollinating flowers, and dispersing seeds.

  • Bats have excellent night vision. Fruit bats use their eyesight and sense of smell to find fruits and flowers. Bats that hunt insects, fish, or frogs can also "see" with sound. This is called echolocation. Bats that use echolocation usually have large ears and leaf-shaped flaps of skin on their noses. This helps them direct the high frequency sounds they make.

Facts about bats: mammals - 0 views

  • There are more than 1,000 species of bats in the world! They live on every continent of the world, except Antarctica. Bats do not live in areas where it is very hot or very cold, and there are some remote islands that are not home to bats.
  • Bats are mammals. They account for more than 25 percent of all the mammals on the earth! Bats are the only mammals that can fly.
  • Mother bats have one baby in their litter. The baby bats are called “pups.” When a pup is born, it usually has no hair and its eyes are closed. It clings to the mother bat and drinks milk from her. When the pup is about four months old, it learns to fly.

  • Depending on the species, bats can be gray, brown, white or reddish brown.
  • Bats have teeth and chew their food. Seventy percent of all bats eat insects. One bat can eat more than a thousand insects in one hour!
  • The largest bats have a wingspan of more than six feet. However, most are smaller.
  • Many people do not like bats and are afraid of them because they think all bats have rabies. Rabies is a virus that is transmitted to animals and people through animal bites. A study by the University of Florida has shown less than one-half of 1 percent of all bats have rabies. It is more likely for a person to be bitten by an unvaccinated dog or cat.
  • People also think vampire bats will try to attack humans. That is simply not true.
  • Bats are not a danger to people and are actually quite valuable. Very few carry rabies, and they help to control the insect population. They also help seed new plants and pollinate our crops!
