The gray myotis is a medium-sized bat with uniform gray fur. It lives in caves in the southeast of North America and hunts insects at night.
The gray myotis differs from related myotis species by its uniform gray fur without shine and large size. It is important for nature because it destroys many harmful insects and serves as an indicator of the purity of cave ecosystems.
