Hog-nosed Bat

Spotted something wrong?

Kitti's hog-nosed bat, also called the bumblebee bat, is one of the smallest mammals in the world: it weighs around two grams and measures some three centimetres. It owes its name to a flattened muzzle with nostrils shaped like a pig's snout. It lives in colonies inside limestone caves and comes out to hunt insects for very short spells, at dusk and at dawn. Its range is tiny and highly fragmented, tied to a handful of karst systems.
