Sloths are a member of the Xenarthra order, a group of mammals with specialized habitats and abilities.
Sloths are very cautious creatures and rarely leave the trees they call home; when on the ground, they cannot support their own weight and must drag themselves forward using their forelimbs and claws.
Sloths are usually born without embryonic membranes and are placed on the mother's chest where it may nurse and hide from predators in the mother's long hair.

 What is a Sloth?
The sloth is very slow and deliberate in its movements, living upside down in rainforest trees for most of its life.
Sloths seldom descend from their arboreal homes because they do not need to drink water; they get as much hydration as they need from leaf consumption.
Sloth’s stomachs have several compartments, loaded with tiny bacteria that help break down the cellulose of leaves, yet their metabolism remains sluggish.

 Sloth - Crystalinks
Sloths are medium-sized South American mammals belonging to the families Megalonychidae and Bradypodidae, part of the order Pilosa.
Even so, leaves provide little energy, and sloths deal with this by a range of economy measures: they have very low metabolic rates (less than half of that expected for a creature of their size), and maintain low body temperatures when active (30 to 34 degrees Celsius), and still lower temperatures when resting.
Bones of a newly discovered ground sloth that is the oldest of its kind ever found in North America have been uncovered by a University of Florida research team.

Scientists distinguish between the ancient ground sloth families by the number of digits, number and size of teeth, and shape of the skull.
Giant ground sloths also apparently walked upon the sides of their feet when traveling from place to place: a condition called a "pedolateral" foot.
It is possible that the ground sloths' numbers dwindled over time due to a combination of climate changes, predators (including early humans), and the inability to effectively compete for food and resources.

Further analyses found that the sloth had digested seven different groups of plants that are related to contemporary plants common in high-elevation desert scrub.
Even more interesting, however, is that the plants the ground sloth was eating thousands of years ago are now found 2600 feet higher in elevation than where the dung was found (Poinar et al.

Further, the three central claws of the hind foot were well-developed and touched the ground, presumably allowing these animals to move more easily and with greater stability than other ground sloths.
Of the two ground sloth families (Megalonychidae and Megatheriidae), the former first appeared in the early Oligocene (about 35 million years ago) of Patagonia, and the former in the late Oligocene (some 30 million years ago) beds of South America.

The giant sloths first appeared in South America in the Early Oligocene Epoch (36 to 22.5 million years ago), and they survived up until recent times, only becoming extinct during the Pleistocene Epoch (1.8 million years ago to 10,000 years ago), during the last Ice Age.
From the Miocene Epoch (22.5 to 5 million years ago), the sloths diverged into two different forms: the giant ground sloths and the smaller tree-dwelling sloths which survive today.
