Nothing to see here. Just a vampire bat enjoying a bowl of blood next to a jack-o'-lantern 🎃 We get the blood to feed our colony from Penn State! The Block and Bridle Club collects it from the cattle they use for teaching and sells it to us as a fundraiser to support the club & club activities. #BatAppreciationMonth | Philadelphia Zoo

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. 🎥Crazy Monsters | Smithsonian Channel
