Edentata and Xenarthra are orders of placental mammals that lack incisors and canines. They have bone-like osteodentin instead of enamel on their teeth. Armadillos have armor plates and dig with claws. Sloths live in trees and have claws and fused toes. Anteaters have a long sticky tongue and no teeth, using their keen sense of smell to find ants and termites.
