This cute-looking bloodsucker is called a common vampire bat. Luckily common, in this case, don't mean "widespread" and these bats can only be found in some parts of Mexico, Central America, and South America. However, their name does suggest their feeding habits. These leaf-nosed bats do enjoy mammalian blood, particularly that of livestock. While they do not pose a real threat to humans, one should be advised to not handle them or visit where common vampire bats live.
