    • edentata In mammalogy, a Cuvierian order of mammals; the edentates. The term is literally incorrect, and in so far objectionable, few of these animals being edentulous or toothless; and the Linnean equivalent term, Bruta, is often employed instead. But the name is firmly established, and the members of the order do agree in certain dental characters, which are these: that incisors are never present, and that the teeth, when there are any, are homodont and (excepting in Tatusiinæ) monophyodont, growing from persistent pulps, and being devoid of enamel. The Edentata are ineducabilian placental mammals, with a relatively small cerebrum of one lobe, but otherwise very diversiform in structure, appearance, and mode of life; the old-world forms are likewise widely different from those of the new world; most edentates are of the latter. The armadillos, sloths, and ant-eaters of America, and the fodient ant-eaters and scaly ant-eaters of Africa and Asia, represent respectively five leading types of Edentata, affording a division of the order into the five suborders Loricata (armadillos), Tardigrada (sloths), Vermilinguia (American ant-eaters), Squamata (scaly ant-eaters or pangolins), and Fodientia (digging ant-eaters or aardvarks). The tardigrades, including a number of gigantic fossil forms, as the mylodous and megatheriums, formerly called Gravigrada, are herbivorous, and the living forms are all arboricole. The others are carnivorous and chiefly insectivorous, and it is among these that the entirely toothless forms occur, as in the ant-eaters. The Cuvierian Edentata included the Monotremata, now long since eliminated.
