Did you know that Iguanas have a 'third eye'? Their parietal eye, a pale scale on top of their head, isn't actually used for vision though, instead it's used to regulate hormone production.
And while we're on the subject of lovely lizards... we couldn't resist mentioning this teeny weeny one which has just been discovered in Madagascar. The miniature chameleon reaches a maximum of just 29mm in length!
Happy Friday all!
