I think iguanas are so strang looking. They have rough skin and large eyes
Yes they have a row of spines down their back and a tiny third eye on their head.  Its odd!
I did not know about the third eye of iguanas. That is so weird!
Yes the green iguana is the most common - it is the one usually kept as a pet
I have seen several of iguana that were being kept as pets. They seem to just sit there all day.
Iguanas can live up to 20 years if they are cared for properly
Wow, that is so much better than the life expectancy of a hamster!
Most of the time though the diet and lighting and other conditions for iguanas in captivity are inadequate and they die within the first year :-(
