There are actually about 6. The big guy, the big gren one which we think is the female and on warm sunny days (last summer) we saw ones that were about 12" and very green. Of course the neighbors all think we should prune our shrubs - even cut them down and keep everything manicured, but we like the lizzard sanctuary. I know that the Iguana's aren't well liked, but I have many pictures of them. I live on a pond and there is another pond 1/2 block away and a canal 1 1/2 block away. Lots of iguanas. I have to leave the dog home when I want to take pictures. I have some of some very large ones. I should post some more in my gallery. Yes, I am a lizzard freak.
