One of the many interesting facts about bats is that they are the only flying mammal in the world, as flying squirrels do not technically fly. Despite this unusual characteristic, bats possess the same traits as their mammal relatives, such as having hair and being warm-blooded.
There are more than 1,000 species of bats living in many different habitats throughout the world. Some bats live in caves, whereas others live in trees or in people's attics. Bats also eat a wide variety of different foods, such as insects, fruit, frogs, fish and blood, depending on the species.
Bats are nocturnal, meaning that they are mostly active at night. They find their prey by means of echolocation, which is a process by which a bat sends out sound waves into the night. When the sound waves hit an object, they bounce back to the bat, alerting the animal to the presence of either an obstacle to avoid or food to pursue.
Scientists refer to young bats as pups. A mother bat gives birth to either one or two pups at a time, and the young bats grow up at such a rapid rate that they may be ready to start hunting within a month of their birth.
