There over 1,300 species of bats in the world, which constitute one-third of the total sum of mammals in Israel. Most people are not aware of them and their fantastic ways of living, because contrary to other mammals, bats do not walk or swim (although they are capable of doing both), but rather fly actively. They are also nocturnal, and unlike most mammals and birds their main sense is not sight but hearing. In order to find their way around, bats omit calls and listen to the echoes they produce in order to navigate. This is also how they find their prey, which is comprised of a variety of animals such as insects, scorpions, fish, frogs, and toads, as well as nectar and fruit. Each species of bats has a special diet and unique behavioural, anatomical and physiological adaptations for this purpose. Bats are beneficial to people by pollinating flowers of many plants, consuming enormous quantities of insects that spread malaria and damage agricultural crops and producing valuable fertilizer-guano. In spite of these benefits, people around the world have created many superstitious beliefs and legends about bats and their behavior. This book describes the biology of bats and their complex relationships with humanity.
