Orangutan
Who lives high in the treetops, rarely comes to the ground, and sleeps in a nest? No, it's not a bird, but one of your closest relatives in the animal kingdom--the orangutan of Sumatra and Borneo, who shares 96.4 percent of the same genetic make-up as humans.
These peaceful, red-haired primates spend their days chowing down on fruit, leaves and flowers from trees, along with any stray insects that might be hidden among the foliage. Mom and baby orangs keep busy grooming each other, and then it's early to bed at sunset in a nest of branches.
Because they're larger, the older males are more comfy sleeping on the ground. At close to 200 pounds, they are not only physically bigger than the females, but have different facial features, too. Adult male orangutans have fat, fleshy cheek pads, and moustaches and beards. (But no, they don't have to shave!)
