Hanging around

Sloths are considered lazy creatures because of their slow, ponderous movement – wrongly so, because their behavior can be explained biologically. Sloths eat almost exclusively leaves. It takes a long time for this diet to be broken down in the digestive tract.  All the sloth’s other bodily functions are correspondingly slow: It swings hand over hand from branch to branch at a speed of no more than four meters a minute. In between they even take breaks. Also remarkable: Only about every eight days sloths climb down to the ground to defecate and urinate.
