It's solitary and gathers only in mating seasons. Since 2016, it has been listed as Vulnerable on the IUCN Red List. As a result of farming, deforestation and infrastructural growth, the large panda has been pushed out of the lowland areas where it as soon as lived. In July 2021, Chinese authorities also labeled the enormous panda as susceptible. The oldest recognized big panda was 38 years previous. By 2007, the captive population comprised 239 large pandas in China and another 27 outside the country. It has usually served as China's nationwide image, appeared on Chinese Gold Panda coins since 1982 and as one of many five Fuwa mascots of the 2008 Summer Olympics held in Beijing. Females rear cubs for a mean of 18 to 24 months. It is a conservation-reliant species. It relies on olfactory communication to communicate and makes use of scent marks as chemical cues and on landmarks like rocks or bushes.
The giant panda has the most important masticatory muscles amongst bears, being more than twice as giant as those of the American black bear with an equivalent brain weight; digastric muscle is equal to 30% of brain weight in big panda in comparison with 10% in black bear. Adults measure around 1.2 to 1.9 m (3 ft eleven in to 6 ft 3 in) lengthy, together with a tail of about 10-15 cm (3.9-5.9 in) and 60 to 90 cm (24 to 35 in) tall at the shoulder. The large panda's paw has a digit similar to a thumb and 5 fingers; the thumb-like digit is actually a modified sesamoid bone that helps it to carry bamboo while consuming. Males can weigh as much as 160 kg (350 lb). They weigh between 70 kg (150 lb) and 125 kg (276 lb). Females are generally 10-20% smaller than males. The average weight for adults is one hundred to 115 kg (220 to 254 lb).
Giant pandas give birth to twins in about half of pregnancies. The mother is thought to be unable to produce sufficient milk for two cubs since she does not store fat. It nurses from its mom's breast six to 14 times a day for up to half-hour at a time. The mom will select the stronger of the cubs, and the weaker cub will die because of starvation. One to two weeks after delivery, the cub's pores and skin turns grey where its hair will finally turn into black. If twins are born, often just one survives in the wild. A slight pink color may appear on the cub's fur, because of a chemical response between the fur and its mother's saliva. A month after delivery, the color sample of the cub's fur is fully developed. The father has no part in helping increase the cub. For three to four hours, the mother could depart the den to feed, which leaves the cub defenseless.

It has been estimated that an grownup panda absorbs 54.8-66.1 mg (0.846-1.020 gr) of cyanide a day by means of its weight loss plan. During the shoot season from April to August, the large panda stores a considerable amount of meals in preparation for the months succeeding this seasonal period, through which it lives off a weight-reduction plan of bamboo leaves. Ingestion of such a big quantity of fabric is feasible and vital because of the speedy passage of large quantities of indigestible plant material by way of the brief, straight digestive tract. To prevent poisoning, they have evolved anti-toxic mechanisms to protect themselves. The typical large panda eats 9 to 14 kg (20 to 31 lb) of bamboo shoots per day to compensate for the restricted vitality content of its diet. Given this voluminous weight loss program, the large panda defecates up to 40 instances a day. About 80% of the cyanide is metabolized to less toxic thiocyanate and discharged in urine, whereas the remaining 20% is detoxified by other minor pathways.
