Sloth fur also exhibits specialized functions: the outer hairs grow in a direction opposite from that of other mammals. In most mammals, hairs grow toward the extremities, but because sloths spend so much time with their legs above their bodies, their hairs grow away from the extremities in order to provide protection from the elements while the sloth hangs upside down. The fur may also provide camaflague. Their slow moving habits also conceal them from predators.
Anteaters food consists mainly of termites, which it obtains by opening their nests with its powerful sharp anterior (front) claws. As the insects swarm to the damaged part of their dwelling, it draws them into its mouth by means of its long, flexible, rapidly moving tongue covered with sticky saliva. The giant anteater lives above ground, not burrowing underground like armadillos or aardvarks.
Armadillos are prolific diggers, and many species use their sharp claws to dig for food such as grubs, and to dig dens. The armor is formed by plates of dermal bone covered in small, overlapping epidermal scales called "scutes". This armor-like skin appears to be the main defense of many armadillos, although most escape predators by fleeing (often into thorny patches, from which their armor protects them) or digging to safety. Only the South American three-banded armadillos (Tolypeutes) rely heavily on their armor for protection. When threatened by a predator, Tolypeutes species frequently roll up into a ball.
