Chameleons have the ability to stretch their tongue up to one and half the length of their body. They even have very long tongue, which they use to catch flying preys. This way they can catch flying preys as well as preys, which are placed far off. They have three toes with two of them facing one side and the third in other direction. This structure helps them to get a firm grip, which facilitates their tree climbing habit. They spend most of their lives on treetops. Some of them also are gifted with prehensile tails, which are also used to take good grip while climbing.
Another amazing fact of chameleons is that they rotate their eyes in two different directions. Both the eyes are independent of each other. The structure of the eyes is globular which they use to rotate and get view of a larger radius. The eyes are used to watch out for enemies and as well as hunt for food. Along with insects and slugs they also eat plants.
