They eat plentiful flower nectar that is available year round in tropical climates, and fruit. The megabats maybe bigger in size, but the microbats are the dominant ones when it comes to numbers. There are 750 species of microbats. They are found on every continent except Antarctica and in every landscape except the hottest deserts and the coldest Polar Regions. The false vampire bat is the world's largest microbat, measuring three feet from wing tip to wing tip.
Microbats can see with their ears.
This is called echolocation. They fly with their mouth open, sending out high-pitched noises called, ultrasounds, which bounce off objects. If the echo returns quickly to the bat, then it knows that an object such as a rock, tree, or insect is nearby. Scientist believe that certain bats that have folds of skin, known as nose leaves, around their nostrils help with the process of echolocation by aiming a bat's sound waves in different directions. California leaf-nosed bats can find bugs by listening for their footsteps or wing beats.
