Thanks all. I'm not too bothered what he is, I love him anyway! I presumed he was a normal, and then came across some photo's of jungles and thought they looked very similar. He has a kind of checkerboard patterned belly. Pretty normal I think. I just wondered if he was a jungle, as I read somewhere that the King gene can make them a bit snappy, and he is pretty fiesty for a corn. That could just be because he was unsettled in his new home though. He hasn't bit me for a while, but did strike at my son yesterday.
He's my first reptile, and i'm really enjoying it. Fascinating creatures!
