Chameleons

Chameleons make ¹_____ (USUAL) pets so buying one is a decision that should be made very carefully. They have complex ²_____ (ENVIRONMENT) requirements, and because some are caught ³_____ (LEGAL) you should make sure you buy one from a responsible pet store. It can’t be said with complete ⁴_____ (ACCURATE) how many species of this reptile there are, but it may be as many as 200. Almost all species can change colour and it is thought by many that they do this to look the same as their ⁵_____ (SURROUND). However, this ability to transform their ⁶_____ (APPEAR) is actually a form of emotional communication. Most chameleons show this form of ⁷_____ (BEHAVE) when they are anxiously hiding from deadly predators, such as snakes and birds, and some do this when they are angry. A chameleon’s tongue can be twice the ⁸_____ (LONG) of its body, which means it can catch its prey from a ⁹_____ (DISTANT) without being seen. Somewhat unbelievably, they have eyes that allow them to have 360-degree ¹⁰_____ (VISUAL) around their bodies. They also have special toes that are similar to a human’s thumbs, which allow them to climb plants and trees. These adaptations make them fascinating creatures to observe.
