Bats are mammals in the order Chiroptera.
Their most distingushing feature is that their forelimbs are developed as wings, making them the only mammal capable of flight.There are estimated to be about 1,100 species of bats worldwide, accounting for about 20 percet of all mammal species. About 70 percent of bats are insectivorous.
Most of the remainder feed on fruits and their juices; three bat species sustain themselves with blood and some prey on vertebrates..
