This is actually a blood-sucking animal that always makes people feel intimidated, and the two representative species are mosquitoes and bats. Of course, not all mosquitoes and bats in the world suck blood, and blood-sucking species are only a small fraction of them. Most mosquitoes and bats still like to eat nectar and drink sap.
Vampire bats also have their own evolutionary history. The largest vampire bat ancestors discovered by scientists are the Dracula bats found in South America and Venezuela. This ancient bat is named Dracula, which shows its unshakable position in the vampire world. This vampire bat probably lives between 100,000 and 2.5 million years ago, which is a relatively long-lived bat.
Dracula bats can reach a wingspan of 0.5 meters, and this thing flies in groups in the sky, which is indeed a bit frightening. Bats are a huge void in human paleontology, just like pterosaurs, because their skeletons are hollow and fragile, and they are difficult to preserve.
The world's earliest bat was born in North America 5220 years ago, when the extinction of dinosaurs has been more than 10 million years, the era of the rise of the official mammals. Bats are the only mammals in the world that can fly. Vampire bats can only be regarded as a different species of bats in more than 1300 species, and there are currently only 3 species of vampire bats living in the Americas, all of which are descendants of Dracula bats.
Vampire bats are a big problem for the local livestock industry, because when bats suck blood, they also spread disease, making livestock sick. There are currently few records of vampire bat bites. The extinction of the Dracula bat occurred more than two million years ago, and the reason for its extinction remains a mystery to this day. What do you think?
