A false vampire bat is a type of bat from the family Megadermatidae, often referred to as false vampires because they were mistakenly believed to suck blood, similar to vampire bats. In actuality, these bats are insectivorous or carnivorous, feeding on a diet that can include insects, small birds, rodents, and even other bats. False vampire bats are found in many tropical and subtropical regions around the world. They are characterized by their large size, big eyes, and long ears.
