Amazing Facts About Beloved Panda

Giant pandas are native to China and they're considered to be one of the national treasure of China. That said, they are still being endangered, the factt there are less than 1900 live in the wild is insane, and about 300 in the zoo around the world. We gathered some facts about these beloved black and white bears for you to appreciate these precious creatures.

Size, habitat and diet

For many years, scientists wondered whether pandas were a type of bear, raccoon or something all their own. But plenty of genetic studies have made it clear that pandas are a type of bear, according to the San Diego Zoo.

Also called great pandas, parti-colored bears, bamboo bears and white bears, giant pandas are distinguished from other pandas by their large size and black-and-white coloring. Their bold coloring provides camouflage — giant pandas are nearly invisible in dense patches of bamboo, according to the Smithsonian National Zoo.

Giant pandas grow to be 27 to 32 inches (70 - 80 centimeters) tall at the shoulder, 4 to 5 feet (1.2 to 1.5 meters) long and can weigh up to 275 lbs. (125 kilograms), according to the San Diego Zoo Their size is about the same as an American black bear. By comparison, the giant panda's distant relative, the red panda, is only 20 to 26 inches (50 to 65 cm) tall and weighs 10 to 20 lbs. (4.5 to 9 kg).

In the wild, giant pandas are only found in the remote, mountainous regions of central China, in Sichuan, Shaanxi and Gansu provinces, according to the National Zoo. In this area, between 5,000 and 10,000 feet elevation (1,524 - 3,048 m), are the cool, wet bamboo forests that giant panda's call home. The large bears make their dens from hollowed-out logs or stumps of conifer trees found within the forest.

A giant panda's appetite for bamboo is insatiable. They eat bamboo 12 hours a day, which adds up to 28 lbs. (12.5 kg) of bamboo each day, according to National Geographic. Giant pandas have a special bone that extends from their wrists called a "pseudo-thumb," according to the San Diego Zoo. They use their pseudo-thumb to hold and manipulate the bamboo.

Bamboo is relatively low in nutrients, which is why pandas have to eat so much of it. In order to get a variety of nutrients, pandas eat various parts of the bamboo plant and will seek out bamboo that's sprouting new shoots and leaves (the young shoots and leaves contain higher amounts of nutrients, including calcium, nitrogen and phosphorous) at different times of the year. In the summer, giant pandas will climb 13,000 feet (3,962 m) up the mountains of their home area to feed, according to the National Geographic.

Sometimes there isn't enough bamboo around to sustain the large bears, so giant pandas will occasionally supplement their bamboo-diet with rodents, fish, insects or birds.

Panda life

For the most part, giant pandas are loners. They dislike being around other pandas so much that they have a heightened sense of smell that lets them know when another panda is nearby so it can be avoided, according to the National Geographic. If they do come in contact with one another they'll growl, swat and bite each other until one gives up and leaves.

On average, a giant panda's territory is about 1.9 square miles (5 square kilometers). To mark their territory, giant pandas secrete a waxy scent marker from a scent gland underneath their tail. Other giant pandas can likely tell the sex, age, reproductive condition, social status and more by sniffing the potent marker, according to the San Diego Zoo.

The only time that giant pandas seek each other out is during their spring mating season. Males will use their sensitive smelling ability to sniff out a female when ready to mate. Females mate every two to three years.

Male pandas, like many other mammals (but not humans) have a baculum, a bony rod in the soft tissue of the penis. In most bears, it is straight and directed forward. However, in giant pandas, it is S-shaped and directed backward, according to the Animal Diversity Web.

The average gestation time is 135 days, but ranges between 100 and 180 days. Females give birth to one or two cubs (although the second cub usually doesn't survive) that only weigh 3 to 5 ounces (85 to 142 grams) and are about the size of a stick of butter, according to the San Diego Zoo. The cubs are completely blind for about 50 to 60 days and begin crawling at about 10 weeks of age. [Gallery: Baby Panda Pics]

Cubs start eating bamboo between 7 and 9 months of age and continue nursing until they are 18 months, when the cub is weaned and sent to live on its own. Female giant pandas reach maturity at 4 to 5 years old and the males at 6 to 7 years old.

Pandas are the most vocal of all bear species, according to the San Diego Zoo. A bleat, similar to the sound of a lamb or goat kid would make, is one of the more distinctive vocalizations of the panda, and is typically used as a greeting. Other vocalizations include honks, huffs, barks and growls, while cubs often croak and squeal.

Giant pandas are known to be curious and playful. In captivity, they're often found playing with enrichment items such as toys and puzzles and performing somersaults, according to the San Diego Zoo.

Conservation status

The International Union for Conservation of Nature and Natural Resources (IUCN) categorizes giant pandas as vulnerable. This is an improvement compared to the giant panda's status in the 1980s, when they were listed as rare by the IUCN. When the latest assessment was made in 2014, the population of the giant panda appeared to be increasing.

There are 67 panda reserves in China that protect around two thirds of the giant pandas in the wild and more than 50 percent of the giant panda's habitat, according to the World Wildlife Fund.
