1. They spend up to 12 hours a day eating. Because bamboo doesn't contain many nutrients, a giant panda has to eat constantly to stay healthy. An adult panda can gobble up 26 to 84 pounds (12 to 38 kg) of bamboo every single day!

2. They have a special "pseudo-thumb" just for bamboo. Giant pandas have five fingers plus an enlarged wrist bone that acts like an extra thumb! This special "thumb" helps them grip slippery bamboo stalks tightly while peeling off the leaves.

3. Newborn pandas are as tiny as a stick of butter. When a giant panda baby is born, it is pink, hairless, blind, and weighs only about 3 to 5 ounces (100 to 140 grams)—making it 900 times smaller than its mother!

4. Their digestive system is actually built for meat. Even though 99% of a giant panda's diet is bamboo, their stomach and intestines are designed like a carnivore's! They kept the digestive traits of their bear ancestors, which is why they digest bamboo inefficiently and must eat so much of it.

5. They do somersaults and handstands. Young pandas love to play by doing tumbling somersaults down grassy hills! Even cooler, adult pandas often do full handstands against trees so they can leave their scent markings higher up the trunk to mark their territory.

6. They don't hibernate like other bears. Most bears in cold regions sleep through the winter, but giant pandas can't! Because their bamboo diet doesn't allow them to store up enough body fat, they simply trek down to warmer mountain valleys in the winter to keep eating.

7. They poop dozens of times a day. With all that tough, fibrous bamboo passing through their bodies so quickly, an adult giant panda can poop up to 40 times in a single day!
