I am a firm believer in natural selection. I think that if snakes of that size were able to survive and propagate their species in the southeastern and northern united states they would have been here already. There are too many natural predators that will take advantage of a large slow moving snake, especially in the winters when the snakes no doubt get slow and lethargic and would be an easy meal. I also think that it would be very difficult for a snake of that size to hibernate and survive a freeze. I'm no expert but it would seem to me that the fact that they have such a large body size means they need a lot more heat than a smaller snake to thermo regulate, and as a result could possibly not be able to survive where temperatures dropped into the 40's and low 50's. Just my two cents.

I agree in fact the area iguanas when winter night temps drop to 50s or bit less head for the canals as the water stays warm .



A month of cold with no escape would kill iguanas-pythons,etc here but the days even in winter are usually warm/hot enough and the warm water is also a place many seek out.



I have gone fishing at night and have lost count how many iguanas I see in water if winter night temps under 60 even under 60 as a whole rare in S.Florida .

I have never seen a python but imagine must be same .



Without at least a warm place to avoid the cold if prolonged cold they would die. I couldnt fathom one surviving a NC winter .



Dont think they are even found in N.Florida
