A scenic picture of two gorillas hugging on a tree branch located in Seattle, Washington at the Woodland Park Zoo. Gorillas eat some 200 types of leaves, tubers, flowers, fruit, fungus and some insects. Favorite foods include bamboo, thistles and wild celery. Gorillas do not drink water. They obtain all the moisture they need from the vast amounts of foliage they consume. Males consume approximately 50 lbs. a day.
