There are approximately 1,100 species of bats found worldwide. And around 110 species of bats are present in India. They are the only mammals with true flight, which is primarily responsible for their global distribution. Their flight organs are the lateral extensions of the skin, the patagia supported by the forelimbs and their very elongated digits, except the first. The patagia may also include the hind limbs and tail. The hind limbs are relatively short and weak, with the knees turned backwards like the elbows. This renders the bats helpless on the ground. The five digits of the hind limb and the first two digits of the forelimb bear claws. All bones are thin to reduce body weight. The senses of touch and hearing are remarkably developed. Although bats have eyes and see well, they guide themselves during their flight using the radar principle. They produce supersonic sounds which are reflected by disturbing objects and perceived by the ears. The penis contains a bone. Usually, there are only two udders located on the thorax. They only produce one or sometimes two young at birth. They are nocturnal animals and spend the day hanging upside down on various objects with the claws of one or both feet.
