Get this - there are 950 different species of bats in the Amazon, so you'd best like them! The Amazonian vampire bats are the only true vampire bat in the world, i.e. the eat blood! In order to do this, the vampire bat has had to adapt its body so that it can move about silently without being detected. Carefully though, it is not unheard of for vampire bats to sneak up on humans and use their razor sharp teeth to scoop out small amounts of human skin; thereby letting your blood flow, which it then laps up (in much the same way as your cat at home does with the milk!)
