Imagine trying to survive in cool, misty mountain forests in China. For many animals, a habitat like this would be impossible. Yet the giant panda, a mammal about 1.5 meters long, thrives there, thanks to features that scientists call adaptations: traits that help a living thing survive in its environment.
Consider an extra thumb-like wrist bone: this adaptation helps it grip bamboo stalks. Equally important is strong jaws and wide, flat teeth, which crush tough bamboo. Without these traits, the giant panda would struggle to last a single season.
As a herbivore, the giant panda is an animal that eats only plants; it depends on bamboo. Its behavior matters as much as its body: it spends up to 14 hours a day eating. Behaviors like this are adaptations too, even though you cannot see them in a photograph.
The next generation faces the same challenges. Young giant pandas, called cubs, depend on their surroundings and on adult care. A newborn cub is pink, blind and about the size of a stick of butter.
Perhaps most remarkable of all: because bamboo has little energy in it, a panda may eat more than 12 kilograms of it in a day. Facts like this remind us that every animal's body tells a story about the place it lives.
