Introduction: Bats can range in size from 1.14-1.30 inches and have a body mass of .07 ounces. Bats weigh up to 3lb and have a wing span of 2 feet. There are over 1100 different species of bats worldwide, which accounts for 20 percent of all mammals on earth. Bats are located almost everywhere in the world except for deserts and polar regions.
Biology: Bats mainly eat insects which are found by using their radar, but some cases bats have been known to eat fruits. Less than 1 percent of bats carry rabies. Bats that do have rabies are usually disoriented, clumsy and unable to fly. Bats have extremely small teeth and can bite a sleeping person without the bite being felt. Female bats have only one newborn each year and are called pups. Pups feed on the milk from the mother bat in the roost for eight weeks or until they are able to fly. Bats become sexually mature at the age of two and can live up to 30 years.
Habits: Bats are for the most part only active at night. During the day bats tend to sleep while hanging upside down. Bats try to avoid flying in the rain because the rain affects their echo location, thus making it difficult to find food. Bats live in caves and other dark areas in colonies which may reach a population of up to one million. Bats communicate by making many different types of sound. To survive the winter many bats will migrate, but if conditions are adequate, bats will hibernate in structures over the winter. This is possible because bats can regulate hypothermia by going into a torpor which can last several months.
