This is an academic video with information about bats and the different species that exist around the world. These mammals have very unique physical characteristics that are somewhat unpleasant for some people, however, they play a very important role within the environment in which they live, as they are involved in the pollination of plants and they balance the amount of insects that are in their environment, among other things. They are not dangerous to humans, however, humans represent the greatest danger to these animals, as pollution, invasion of their shelters and the destruction of their habitat, have reduced the population of these animals.
