Are mermaids, vampires,... real?

1. Vampires
Tales of vampires which have been the inspiration for horror movies the world over originate from a small flying mammal that weighs less than two ounces. Of the three species of vampire bat the one that has contributed to the misunderstanding and fear of bats more than any other is the infamous common vampire bat.
Perhaps an unfair reputation considering that they rarely kill their prey, in fact they can feed without their incision even being noticed due to specially adapted blade like incisors. They are found in the deserts and rainforest of the tropical and subtropical regions of Central and South America, making their homes in caves, mines and tree hollows. If they are unlucky in their night-time search for sustenance for two consecutive nights they will die. Luckily for nursing mothers other bats will regurgitate blood meals to them.
