Bats in Question: the Smithsonian Answer Book - Tapa blanda

Sinopsis

Do bats really drink blood? How fast can bats fly? Are they related to birds? What are the largest and smallest bats? Why do they live in colonies?Long the subjects of myth and superstition, bats have been among the most misunderstood of mammals due to their nocturnal habits, capacity for flight, and strange appearance. Bats account for nearly a quarter of the world's mammal species, yet whenever they are seen they raise questions.Seeking to dispel the myths associated with these remarkable creatures and arguing for their key role in a balanced ecosystem, Bats in Question covers all aspects of bat biology in a practical question-and-answer format. Describing where bats live, how they use echolocation to navigate, and even why they hang upside down, the book also gives the conservation status of all 925 bat species. The author traces the evolution of bats and shows their remarkable diversity by describing each of the major groups in terms of their different body structures and habitats. He also sheds light on bats' complex social systems, extraordinary variation in size, and food preferences that encompass plants, insects and mammals.The book also explores cultural attitudes about bats - telling how, until recently, bats had been relegated to the world of vampires and how they have emerged to take their place in public awareness as important and fascinating members of our ecosystems.
