Not necessarily. Bats, like birds, have wings and can fly. However, bats and birds are really very different.What does a bat look like?Bats look like mice. Their hands and arms are covered by a thin layer(层) of skin. This makes their hands and arms work like wings. Most bats have hair that helps to keep them warm. They have two eyes and can see very well. Bats also have two ears. They can move their ears to listen to sounds. They can also use their hearing when flying so they do not bump into(撞到) things, and they can even use it to find their food.How do bats live?Bats can see well even when its dark. They can hunt for food at night. Many bats eat bugs, while other bats eat fruit. Because they search for food at night, bats usually sleep during the day. Some often sleep in caves, barns, or holes in trees. Others sleep in houses that people build for them. When a bat sleeps, it hangs upside down from its feet.How do bats help people?Bats help people in many ways. For example, some bats eat the bugs that bite people and destroy plants. Bats can also help people by eating fruit. After eating the fruit, bats sometimes drop seeds(种子). The seeds then grow into new plants.Bats are very interesting and unusual animals.
