The main differences between an aardvark and an armadillo are their range, body structure, defense mechanism, and order. While aardvarks are natives of Africa, belonging to the Tubulidentata order, armadillos belong to the Cingulata and are found mainly in the Americas. Aardvarks have short furs that cover their body while armadillos have a bony armor called osteoderm around their body.
