However, despite these reptiles running from the cold, it appears Burmese pythons in Florida have adapted to endure colder temperatures. Burmese pythons, native to Southeast Asia, likely ended up in southern Florida, specifically the Everglades, through the exotic pet trade and the discarding of animals. Like other cold-blooded creatures, Burmese pythons cannot maintain a constant warm, healthy body temperature on their own. Usually, this means it is dangerous for pythons to spend prolonged periods in temperatures below 65 degrees, but Florida's Burmese pythons seem to be adjusting to the state's occasional cold snaps. Burmese pythons are not venomous and average between 10 and 16 feet long when they’re adults, according to The News-Press.
