The lovely changeable lizard.
Although these lizards can be quite large, they only eat insects, and have very small teeth for gripping and crunching their small prey.
If you try and catch them, and they do bite, it is a barely felt squeeze, and they do not even draw blood. They also have a habit of biting and then not letting go (unlike Geckos), as demonstrated ably by my friend in the photo below. (do not try this at home...thank you).
