The animal known for its large ears and ability to dig tunnels is the fennec fox. Native to the Sahara Desert, the fennec fox has distinctive large ears that help dissipate heat in its hot environment and improve its hearing to detect prey. Fennec foxes are adept diggers, creating extensive burrows to escape the desert's harsh climate and to keep cool during the day. Their social behavior often involves living in family groups, and they primarily feed on small animals, insects, and plants found in their arid habitat.
