Have you ever owned a Iguana? I recently got a female and a male. They can vary in length based on the gender
No way I am so scared of iguanas do you play or hold them?  
O let them sit in a tree most of the time and they love it. I just learned that they have a third eye and it senses light
 Where is the third eye located?
It is on the top of the head
Wow at the top so they actually don't need that one most likely, what kind of things do they feed off of? 
The mostly eat bugs, But the third eye looks like a pale scale and it can only make out light nothing else.
So that is how they determine the time of the day from that eye, what kind of bugs like crickets or flies? 
Yeah in the wild im sure they hunt small rodents as well. The come from south America and the carribbean
I seen pictures of iguanas in the Caribbean and those things look big as dogs lol I would be to scared.
