How many bats are left in the world?

It is estimated that there are about 1,300 species of bats in the world, with populations varying widely depending on the species and region. Some species, such as the common pipistrelle bat (Pipistrellus pipistrellus), are widespread and abundant, while others, such as the Rodrigues fruit bat (Pteropus rodricensis), are critically endangered and may have fewer than 10 individuals remaining.

To get a more accurate estimate of the total number of bats in the world, it would be necessary to conduct a comprehensive survey of bat populations in every country and region. This would be a challenging and time-consuming task, as bats are often difficult to detect and count. However, such a survey would provide valuable information about the status of bat populations and would help to inform conservation efforts.
