On the appearance characteristics and living habits of pandas
Giant pandas are chubby, like bears, with round heads and short tails. Head and trunk length 1.2- 1.8m, tail length 10- 12cm. The weight is 80- 120 kg, and the maximum weight can reach 180 kg. Pandas are slightly heavier, and males are slightly larger than females.
The head and body are black and white, but black is not pure black, and white is not pure white, but brown in black and yellow in white. The Qinling area is large, with rough body hair and slightly brown belly hair. Minshan (especially Qingchuan Pingwu) is smaller, with thinner body hair and less brown belly hair, but Liangshan is not small.
The black-and-white appearance is conducive to hiding in dense forests and trees on the snow-covered ground, which is not easy to be found by natural enemies. Relatively sharp claws and powerful front and rear limbs are beneficial for giant pandas to climb tall trees quickly.
2. Living habits:
Giant pandas spend half their eating time every day, and most of the rest time in sleep. In the wild, giant pandas sleep for 2-4 hours between meals. Lying flat, lying on the side, prone, stretching or curling are their favorite sleep styles.
In the zoo, the keepers feed them regularly, twice a day, so the pandas spend the rest of their time resting. Giant pandas look cute even when they sleep. They are very flexible and can put their heavy bodies in various positions. My favorite posture is to support my legs on a tree and cover my eyes with my hands.

The evolutionary history of pandas;
Giant pandas have a long history. The fossil of Hong Shi Panda, the oldest panda member, was unearthed in Lufeng and Yuanmou, Yunnan, China, with a geological age of about 8 million years ago in the late Miocene. In the long-term harsh competition for survival and natural selection, many contemporary animals have become extinct, but the giant panda is strong and in an advantage, and has been preserved as a "living fossil" to this day.
The ancestor of the giant panda is Lufeng Giant Panda. The standard Chinese name of the giant panda is actually "panda", which means "bear like a cat". This is the earliest panda, which is mainly carnivorous and evolved from a bear-like animal. The main branches of Eocene pandas continued to evolve in central and southern China. One of them appeared in the early Pleistocene about 3 million years ago and was smaller than a panda. Judging from its teeth, it has evolved into an omnivore and an egg-laying bear that eats bamboo.
Since then, this main branch has spread to the subtropics, and fossils have been found in North China, Northwest China, East China, Southwest China, South China and even Vietnam and northern Myanmar. In this process, the giant panda adapted to the life of subtropical bamboo forest, gradually became bigger and lived on bamboo. The giant panda reached its peak in the middle and late Pleistocene 500,000-700,000 years ago.
Giant pandas in life have well-developed molars, and their claws have a "thumb" in addition to five toes. This "thumb" is actually a specialized formation of a wrist bone, scientifically called "radial sesamoid bone", which mainly plays the role of holding bamboo.
Fossils show that the ancestors of giant pandas appeared in the early Holocene 2-3 million years ago. Hundreds of thousands of years ago, it was the heyday of the giant panda, belonging to the saber-toothed elephant paleontology. The giant panda's habitat once covered most of the eastern and southern parts of China, from Beijing in the north to southern Myanmar and northern Viet Nam in the south.
Fossils are usually found in temperate or subtropical forests at an altitude of 500 ~ 700 meters. Later, animals died out in the same period, but the giant panda has survived to this day, maintaining its original ancient characteristics.
