I'll bet if you could get it out of him you would find that a lot of those poulations were near importers. Some of them spread further most do not. The exotic thing gets way blown out of proportion here. It is true that you can find lots of Iguanas all over south fla. but unlike niles and others Iguanas were almost mainstream and they can tolerate a lot more cold than other species add to that, that the majority of Tropical vegetation in S. Fla is from Central and S. America (their native habitat/food) and you can see why this one is more widespread. I would be really worried about someone in fla. selling me baby sulcattas they claim they found. They might just be baby gopher tortoises and that might get someone in trouble. If there really were populations of sulcattas here someone would definately notice. Thet dig holes bigger than badger holes and I used to play in Badger holes (abandoned ones of course and in Tx. no badgers here.) The minute someone saw one of these holes if they didn't see the tortoise they would scream "sinkhole" and that would scoop the nile story on the 6-o clock news.
