Yesterday I saw a marine iguana sunning its self on top of a busy bush. This bush is on a large lake in the back of our yard. We live in south west Florida. I didnt know what it was, so I went to my computor, and there its picture was. It was large and scary ugly. Could someone please tell me if this poor lost iguana can live in this climate and in this water. We live only a short distance from the gulf. It wasnt small or extremly large. But it was big enough to be very scary looking. Any advice, would be helpful. Thanks, Sarah
