The Mexican big-eared bat is a small mammal with very large ears. It lives in caves and forests of Mexico and southern USA, hunting insects at night using echolocation.
The Mexican big-eared bat differs from related species by particularly large ears and the shape of the nose leaf. It is important for nature because it eats many pest insects and serves as an indicator of environmental purity.
