Have you ever seen an Iguana? They are herbivore lizards? 
Oh yes ive seen them before, Ive always wanted one as a pet, But never had the proper cages or know how to take care of them. 
That would be pretty cool. The iguana is native to tropical countries like South America, Central America, Mexico, and the Caribbean.
Oh cool! I do see them all the time in the news, I hear they are an invasive species in certain places. Do you know how old iguanas live for? 
Usually about 12 years. The small scale behind the iguanas ears that look like spokes are called tuberculate scales.
Oh ok thats not so bad then, How big do iguanas get? Id liek to maybe get one that doesnt grow too big. 
Iguanas range in length including the tail. Some males can get over 5ft in length
