Myotis findleyi

Findley's Myotis

Order: Chiroptera
Family: Vespertilionidae


Conservation Status: Endangered.

Humans - and the animals they take with them, such as dogs - live in more places on Earth than any other terrestrial mammals. Bats in the genus Myotis can probably claim second place in the distribution sweepstakes: they are found on every continent except Antarctica. Some, such as Myotis lucifugus, the Little Brown Bat, have very wide distributions. Others, including Findley's Myotis, which is an endangered species, are very limited geographically. Findley's Myotis is known only from four small islands, Islas Marías, in the Pacific Ocean off the coast of Mexico. Very little is known about its lifestyle, but like almost all Myotis, it almost certainly eats insects, and when it is hunting, sends its echolocation calls out through its mouth.

Range: Total Length: 70-80 mm; Tail: 26-33 mm
