57. Blunt-eared Bat

Tomopeas ravus


The blunt-eared bat is a primitive mammal and is the sole representative of a subfamily of bats. Very little is known about this tiny bat.

This bat is related to a group of fast-flying aerial insectivores.

It has been found roosting under granite boulders and appears to be restricted to the arid and semi-arid coastal regions of Peru.

The main threat to the bats at present appears to be from human activity, in particular fumigation of the caves, which is used to control rabies.
