What animal is black and white, cute and endangered? It can only be the giant panda. 1. Scientists are not sure what's behind their colour, but they think it has something to do with a way of keeping safe. The panda's white body colour helps it hide in the snow. 2. Other scientists believe that their colour may have something to do with finding a mate. However, not all pandas are black and white. There is also a rare brown and white panda.
Scientists say their round faces and way of walking remind us of human babies. 3. Similarly, the dark circles around the eyes make giant pandas' eyes appear larger, so they look so cute.
4. They have noticed that wild giant pandas normally start to be active before sunrise, rest, then reach a second active peak(高峰) again before sundown and then rest until late at night. Daily activities often change with the seasons. In summer and autumn, for example, activity levels are much higher in the daytime than at night.
Many people like visiting pandas in the zoo. It's important for pandas to have a quiet environment. 5. Also, don't throw food to pandas unless the panda keeper tells you it's okay to do so, or it could cause them to get sick.
