Sloths Get a Grip

The sloth is the slowest mammal in the world; so slow that green algae grows on its fur undisturbed. The algae gives the sloth a greenish tint, allowing it to camouflage with the trees in the Central and South American rainforests. All sloths live in trees and can hang from branches with a powerful grip aided by their claws. In fact, because they have such a strong hold on these limbs, sloths have been known to remain hanging from branches even after death.
