Family Desmodontidae is also known as the vampire bat family and comprises three species of bats that feed on the blood of other animals, including cattle and humans. These bats are native to Central and South America and are known for their ability to transmit diseases such as rabies to their hosts. Synonyms for this family include the common vampire bat family, the sanguinivorous bat family, and the hematophagous bat family. Despite their association with horror stories and vampire myths, these animals play an essential role in their ecosystem as pollinators and seed dispersers.
