Xenarthrans are a unique group of mammals that include armadillos, anteaters, and sloths. They are primarily found in the Americas and are characterized by their distinct skeletal features, such as extra articulations in their vertebrae. This group is known for its diverse adaptations to different environments, from the tree-dwelling sloths to the burrowing armadillos. These animals have specialized diets; for example, anteaters primarily feed on ants and termites, while sloths are herbivorous, consuming leaves. Xenarthrans play important ecological roles, such as controlling insect populations and contributing to seed dispersal in their habitats.
