Bats are the only mammals that can fly. They are found all over the world, except in Antarctica. There are over 1,400 species of bats, ranging in size from the tiny bumblebee bat to the large flying fox.
Anatomy and Physiology
Bats have a unique body shape that allows them to fly. Their wings are made of skin and are supported by long bones. Their bones are hollow, which makes them lightweight. Bats also have powerful muscles in their wings that allow them to flap their wings very quickly.
Bats have excellent hearing and eyesight. They use their hearing to navigate and to find prey. Their eyesight is not as good as that of humans, but they can see in the dark.
Behavior
Bats are mostly nocturnal, meaning that they are active at night. They spend the day roosting in caves, trees, or buildings. When they emerge at night, they use their echolocation to find food.
Bats are social animals and they often live in colonies. Some colonies can be very large, with thousands of bats.
Diet
Bats eat a variety of foods, including insects, fruit, nectar, and blood. Vampire bats are the only mammals that feed on blood.
Reproduction
Bats typically give birth to one or two young per year. The young are born blind and helpless, and they are nursed by their mother for several weeks.
Conservation
Bats are an important part of the ecosystem. They help to control insect populations, and they pollinate plants. However, bats are facing a number of threats, including habitat loss and pesticides.
