Scelidotherium is another genus of large South American Pleistocene ground-sloths, characterized, among other features, by the elongation and slenderness of the skull, which thus makes a decided approximation to the anteater type, although retaining the full series of cheek-teeth, which were, of course, essential to an herbivorous animal.
The tamandua anteaters, as typified by Tamandua (or Uroleptes) tetradactyla, are much smaller than the great anteater, and differ essentially from it in their habits, being mainly arboreal.
The little or two-toed anteater (Cyclopes or Cycloturus didact y lus) is a native of the hottest parts of South and Central America, and about the size of a rat, of a general yellowish colour, and exclusively arboreal in its habits.
Of animals still found may be mentioned baboons and monkeys, the leopard, red lynx (Felis caracal), spotted hyena, aard wolf, wild cat, long-eared fox, jackals of various kinds, the dassie or rock rabbit, the scaly anteater, the ant bear (aardvaark), the mongoose and the spring haas, a rodent of the jerboa family.
The typical and largest representative of the group is the great anteater or ant-bear (Myrmecophaga jubata), an animal measuring 4 ft.
