Bats are the only mammals(哺乳动物) which can fly properly. Other flying mammals have wings of thin skin which cover their sides between their front and back legs. They can only fly from tree to tree, but they cannot change direction when they want to.
All bats fly at night and most of them hunt for flying insects(昆虫), such as bees. The common bat finds its food by making a constant noise that the human ear cannot hear. The bat listens for echoes(回声) of the noise as it bounces(反射) off the insects showing the bat their position.
The Fruit bat feeds on many different kinds of fruit. It does not use echoes but instead has very large, special eyes to see even in low light. The largest Fruit bat has a wing length of 0.75 meters. The Vampire bat drinks the blood of large mammals, and a few bats catch fish, birds and even other bats.
