Did you know it?
As much as 90–98 percent of the panda’s diet consists of the leaves, shoots, and stems of bamboo, a large grass available year-round in much of China’s forested regions. Despite adaptations in the forepaws, teeth, and jaws for bamboo consumption, the giant panda has retained the digestive system of its carnivore ancestry and is therefore unable to digest cellulose, a main constituent of bamboo. Pandas solve this problem by rapidly passing prodigious quantities of the grass through their digestive tracts on a daily basis.
