Bats are flying mammals in the order Chiroptera. The forelimbs of bats are webbed and developed as wings, making them the only mammals naturally capable of true and sustained flight. In this book, the authors present current research in the study of the biology, behavior and conservation of bats. Topics discussed in this compilation include: chiroptophobia (the fear of bats); the reproductive biology of male bats; bats and rabies in Brazil; postnatal development, wing morphology and flight performance of the short-nosed fruit bat; hematophagous bats; prolonged sperm storage in bats and metabolic adaptations in frugivorous bats.
