There are 950 species of this unique flying mammal. Bats rarely land where they are quite awkward; as for rest time, they prefer hanging upside down by the claws on their tiptoes. Bats hunt by night. They mainly are insectivore; some tropical ones can eat fruits and three feeds from little mammals’ blood. In order to move and localise their prey, they use ultrasounds (echolocation) thanks to their vocal cords
