The giant panda is a member of the bear family, yet has some distinguishing characteristics. Giant pandas weigh between eighty to one hundred twenty-five kilograms or one hundred eighty to two hundred fifty pounds (Bies). One obvious difference between giant pandas and other bears is the coloring. The black and white spots are unique to this species. Instead of roaring like most bears, the giant panda makes a bleating noise. They also have what is called a sixth front toe, which is unlike any other member of the bear family. In actuality, the toe is 鈥渁n enlarged wrist bone that functions as a thumb in grasping food鈥?(Giant Panda). The lifespan of the giant panda varies depending on location. Researchers estimate that wild pandas live between ten to fifteen years, but pandas living in captivity can live up to thirty years (Bies).

Also unlike other bears, the giant pandas diet consists mainly of bamboo. An adult giant panda spends approximately ten to twelve hours a day consuming bamboo. Although it has no real nutritional value, bamboo grows all year long. Giant pandas have the sixth toe and the ability to feed upright. These abilities combined with the plentifulness of bamboo make bamboo an ideal food source. The giant panda also has a very muscular stomach wall covered with a thick layer of mucus to aid in the digesting of bamboo (Bies). Giant pandas adapted to their environment several hundreds of year ago. This is seen through their physical features that are unique to this species and very advantageous to eating bamboo.
