The fotsiaondré, also called the habéby, is an unknown hoofed nocturnal mammal inhabiting the Isalo Massif, a semi-arid mountainous, canyon-filled region more than 900 square kilometres in size. It's described as a sheep or goat-like animal with long, furry ears, a white coat with brown spots, a long muzzle, and large, beady eyes. Although they are a ruminant, they have no horns. If confirmed to exist, it would be the only native hoofed mammal in Madagascar. Little is known about its behaviour.
