Bats

Uploaded by jarlocke on Sep 26, 2005

There is an abundant amount of animal species in the world. They all have adapted and evolved to survive in their surroundings. Some have grown fins, others legs, and some have wings. Each adaptation helps them to survive in the particular environment in which they live. Some animals that are members of the same species have adapted and evolved. One adaptation is wings, and they are normally thought to be a feature of birds. One of the only animals that has wings and is not a bird is the bat. The bat is a truly great creature.
