New Zealand lesser short-tailed bat
The New Zealand lesser short-tailed bat (Mystacina tuberculata) is a small-sized omnivorous mammal endemic to the islands of New Zealand. It is one of two extant and three overall terrestrial mammal species unique to New Zealand. Its closest relative, the New Zealand greater short-tailed bat (M. robusta), was last seen in 1965 and is presumed extinct due to intense predation from ship rats introduced in the last few centuries. These bats are also commonly referred to as pekapeka, their Māori-language name. Lesser short-tailed bats have unique adaptations that differentiate them from bats found in other parts of the world.
