Chameleons are reptiles mostly African from iguana family. They’re characterized by their ability to change their body colours: the can become green to maroon different bright colours in between in order to camouflage, defend themselves, seduce, or just show their mood. In order to eat, chameleons can stay still and hidden in trees for several hours until a prey comes and get eaten by them. Chameleons’ tong can be as long as their bodies.
