Sloths—the sluggish tree-dwellers of Central and South America—spend their
lives in the tropical rain forests. They move through the canopy at a rate
of about 40 yards per day, munching on leaves, twigs and buds. Sloths have
an exceptionally low metabolic rate and spend 15 to 20 hours per day
sleeping. And surprisingly enough, the long-armed animals are excellent
swimmers. They occasionally drop from their treetop perches into water for
a paddle.
Sloths are three times stronger than us - from the moment they are
born sloths are able to lift their entire body weight upwards with
just one arm
Sloths are blind in bright daylight - They have a very rare condition
called rod monochromacy which means that they completely lack
cone cells in their eyes!
