Chameleons are very rare to see. Apart from the fact that they are extremely difficult to spot because of their camouflage, interestingly enough they also change colour according to their mood. If they are feeling calm they will be very light in colour and when stressed they turn dark in colour and if you try approaching them they will actually hiss at you in a similar way to a snake. Should a chameleon choose to go on the attack and bite, it wouldn’t hurt us much as they have very small teeth. But it’s best to leave the chameleon to simply go on its way!
