An Iguana? But they look so slow! Except for their tongue[/QUOTE]Iguanas are nasty little creatures, I've been whipped a few times by one and also bit. My friend had a few when we were growing up.
His were quite quick, they were huge too! I think they lived for 15-20 years or something. I couldn't believe how long he had them. I have a bearded dragon and he's so friendly, it's actually that same friend who convinced me to get a beardie.
I think that the lizard you have in that pic would crack the shell of the eggs and eat the insides.
