  2. 2. NATIONAL WILDLIFE FEDERATION BATS Background Origins and Relatives Did you know that the world’s smallest mammal, the bumblebee bat, weighs less than a penny? Bats play a vital role in the health of our natural world, and are fascinating creatures. They are a group of mammals that belong to the group, “Chiroptera,” which means hand-wing. All living bat species fit into one of two sub-groups, the Microchiroptera or the Megachiroptera. Members of the latter group are often called “flying foxes” because of their fox-like faces. They are found only in the Old World tropics, while the Microchiroptera, which are highly varied in appearance, occur worldwide. Diversity and Distribution The more than 1,000 species of bats make up approximately 25 percent of all mammal species, more than any other mammal group except rodents, and they are found everywhere in the world AMERICAN BATS: ONLINE ACTIVITY GUIDE |
