Features

They spend the day in their sanctuaries (underground caves, church bell towers and attics) and sleeping upside-down. They are the only mammals that fly actively. Bats are predominantly insectivorous and usually feed in forests, meadows, pastures and near water.

Description

Flying is made possible by a thin elastic membrane, stretching between their long fingers, legs and tail. While flying, they look quite large, as the span of their wings exceeds 40 centimeters. Although they have developed vision, they orientate themselves by aid of hearing. They deliver high frequency calls and create a picture of the space by listening to their echoes. The highest known age of the greater mouse-eared bat is 37 years.
