The great panda spends up to fourteen hours a day eating its preferred food: bamboo! It has a 'pseudo thumb" which it uses to grab bamboo stems. This bear is usally about 1.5 meters high and weighs 135 kilos. Out in the wild, the panda can reach the age of twenty years old and in captivity about ten years more. As an adult, pandas live alone, but in the first one two years of their lives they live together with their mother before they claim their own territory. As they are threatened by extinction in the wild, various zoos worldwide are trying to breed them - with very little success.
