Bats are the only true flying mammal. They are warm blooded and are covered in fur.They nourish their young with milk. They can fly long distances, using echo location to find their way. As a result they have a highly developed sense of smell and hearing. Bats are represented in Australia by 58 species including the fruit bat,Chiroptera pterpodidae, as well as the rare ghost bat, Macroderma gigas, of central Australia, which is a cannibal bat living on smaller species of its own kind and other animals.
