D
There are about 200 kinds of chameleons(变色龙) in the world that scientists know about. 42% of these kinds of chameleons live in Madagascar.
Scientists used to think these animals do that to hide from danger. But now they know the main reason is to communicate with each other. Chameleons can change colours to draw other chameleons' attention or to warn them to go away. They can use their colours to show that they are angry or scared sometimes. It turns out that they stay safe by moving backward and forward in a strange way. By moving that way, the chameleon looks less like a moving animal.
A chameleon's tongue is very long and moves very fast. To catch food, a chameleon hides in the trees until an insect walks by. A chameleon can catch insects as far away as twice its body length. The end of its tongue is very sticky. When a chameleon catches an insect, the tongue shoots forward at a great speed. And the insect is caught in a flash.
Chameleons are amazing animals. But like many other animals, they're in trouble. This is because the forests and other areas where they live are disappearing or are being changed by people. And when the area is changed too much, it becomes difficult for chameleons to live there. Scientists are working to help the endangered chameleons by learning as much as they can about these colourful animals.
