Lizards are neat. They're like little dinosaurs. The second picture is my favourite. He's really enjoying that rock.

I think, but I'm not sure, that our orangeish friend(s) is/are Conolophus subcristatus. There's another similar-looking species called Conolophus pallidus, the pallidus part meaning "pale"-- but we can clearly see the dark colouring on the back which is characteristic of C. subcristatus.

Note that I'm not an expert on reptiles. I just believe strongly in Cunningham's Law. If I'm wrong, someone will be along shortly enough to tell you what it really is.
