How Vampire Bats Suck Blood for 30 Minutes Unnoticed

Short | 01:57

Thanks to a local anesthetic in their spit, vampire bats are able to drink blood from their prey without being detected. That way, they can feed undisturbed for up to a half hour at a time.


More About This episode

Enter nature's house of horrors and witness a weird and wonderful collection of bats. We've gathered winged beasts from around the globe, from acrobats to bloodsuckers to scorpion hunters and beyond, and detail how they thrive, not only in underground caves but also in arid deserts and tropical jungles. We reveal how 50 million years have equipped these flying mammals with some bizarre adaptations, including ultrasonic hearing, oddly long tongues, and more.
