Giant Armadillo

The giant armadillo holds the record for the most teeth of any mammal, with up to about 100 teeth lining its long, narrow jaws. Unlike the sharp canines or flat grinding molars seen in many other mammals, its teeth are small, peg-like, and completely lack enamel—an adaptation well suited to its insect-based diet, particularly ants and termites that require little chewing. While some non-mammals, such as snails, far exceed this number overall, the giant armadillo clearly stands alone among mammals as the undisputed tooth-count champion in the animal kingdom.
