Brandt's bat (Myotis brandtii) is a species of vesper bat in the family Vespertilionidae. It is found throughout most of Europe and parts of Asia. It is known for its extreme life expectancy relative to its body size, approximately twice that of humans. The Brandt's bat holds the record for oldest bat recorded; in 2006, a banded bat was discovered in a cave in Siberia that had been banded in 1964, making the bat at least 41 years old. It is named for the German zoologist Johann Friedrich von Brandt.
