Bamboo is the primary food source for giant pandas. Pandas are biologically unique, closely related to bears, and have the digestive system of a carnivore. They occasionally hunt for fish or small mammals, however long ago they adapted to a vegetarian diet and unlike their omnivorous cousins, depend almost exclusively on bamboo as a food source. And they eat huge amounts -- as much as 83 pounds each day. For information about the panda’s diet, please visit the Endangered Wildlife section.
