#HappyHalloween! We're celebrating this spooky holiday with bats.
While bats might make some of us squeal and squirm, they are actually an incredible success story: - Of the 5,400 known living species of mammals, more than 1,000 are bats. - They are the only mammals that can truly fly--an ability that arose separately in birds, insects and some extinct reptiles, but has evolved only once in mammals some 50 million years ago, when bats took to the air. - The smallest living mammal is a bat! Found only in Thailand and Myanmar, the bumblebee bat is no bigger than a bee and weighs only about as much as a dime. -
Some bats can walk. Vampire bats, for instance, often crawl undetected onto the bodies of their sleeping prey to bite them and lick their blood.
