These animals are primarily found in the Americas and are characterized by their distinct skeletal features, including extra articulations in their vertebrae. Members of the Xenarthra group have adapted to various habitats, from tropical forests to grasslands. They play important ecological roles, such as controlling insect populations and aiding in seed dispersal. Despite their differences, these animals share common traits that set them apart from other mammalian orders.
