Eulipotyphla is a mammalian order that includes moles, shrews, hedgehogs, and other species. Once classified under the insectivore order, these mammals are generally smaller, ground-dwelling, and feed on invertebrates. The Eulipotyphla are characterized by primitive teeth, poor intellect, small eyes with poor vision, long pointed narrow muzzles, and an excellent sense of smell and hearing. They live in solitary and show strong limbs and claws they use to dig out food from the soil or dig tunnels in the ground in which they spend most of their time or hide from predators. Others like the hedgehog can hibernate.
