Most of the Giant Panda's adaptations involve the bamboo that it relies on (99% of its diet is bamboo). It has developed a very large head due to its larger jaw muscles, required to bite and chew the thick bamboo. In addition, its molars (teeth) have been adapted to be very smooth and large, which is not normal among bears because bears are carnivores. Finally, their digestive system has adapted to their diet of bamboo. The esophagus and stomach has developed a strong lining so it will not tear, the intestines are shorter due to the high cellulose content of bamboo, and the colon is larger since it is putting much more into its body while producing waste less frequently.
