An order of mammals including the armadillos, sloths, and anteaters; -- called also Bruta. The incisor teeth are rarely developed, and in some groups all the teeth are lacking.
EDENTATA, an order of placental mammals characterized by the total absence of median incisor teeth. Such teeth as are found in edentate species are composed entirely of dentine and cement, without enamel; they likewise grow for an indefinite period, and are consequently without root; and so far as yet discovered there is no displacement of the first teeth by any second set except in a few of the armadilloes. This order contains the sloths, armadilloes, and ant-eaters.
