Linne's Two-toed Sloth

You could stare at a tree with a sloth in it and never find the sloth. This animal is a master of camouflage. Its shaggy fur is usually covered with blue-green algae, helping the sloth blend into the treetops. Plus, the sloth sleeps 15 to 18 hours a day, making it even harder to detect. (No wonder people use the word “slothful” to mean lazy!)

Even when it’s awake, a sloth doesn’t do anything in a hurry. It moves slowly through the tree branches, feeding on leaves, shoots, blossoms, and fruit. And just as it eats slowly, it also takes its time "eliminating" -- two-toed sloths poop just once a week!
