For example, flying fox bats have very good eyesight and they use their eyes along with their excellent sense of smell to help find food in the dark. Bats' eyes are better at seeing in the dark. Most see objects only in black and white, but color vision is known to exist in some old world fruit bats. With their strong claws, bats are able to hang upside down in their roosts. Fishing bats also use their claws to scoop up the fish they will eat.
Bats fly by using their hands and wings.
While the wings are flapping, bats can go up or down by moving the membrane between the body and fifth finger. You can tell that a bat is a mammal because it has fur or hair on its body. The fur protects the bat because different colors and designs can serve as camouflage and they can hide from danger. The fur is kept clean by regular licking, somewhat like what a cat does. In the winter it helps keep the bat warm.
