Common pipistrelle bat
This tiny bat might not weigh more than a 2p coin, but look at those nightmarish nashers! Well, they aren’t going to suck your blood or do you much damage, but for the insects it feeds on during balmy summer nights, they are the teeth of pure evil. Common pipistrelles can gobble up to 3,000 insects in just one night!
Want to know something else spooky? The ancient Maya people of South America are said to have worshipped a giant bat-god named Camazotz who was associated with human sacrifice.
