Did u know that in the whole mammals only the bat can fly ? Yeah, its weird but a true fact. A bat wing is better than normal bird wings. The bat’s wing is fleshy webbing is also connecting their arms to their bodies. The bats do all their hunting walking around on the forest floor much like shrews in the rest of the world. In the species of bat only the vampire bats are unique, because they are the only mammals that feed entirely on blood.
