1. Eastern Diamondback Rattlesnake
The biggest venomous snake in North America, the Eastern Diamondback Rattlesnake is undoubtedly one of the most dangerous creatures in the Southeast.
2. Burmese Python An invasive species in the United States, the Burmese python is mostly found in Florida's Everglades. Some of these pythons can grow to be over 20 feet long, making them some of the biggest snakes in the world.
3. Indigo Snake The longest natural snake species in the US is the eastern indigo snake. These non-venomous snakes, which may grow up to 8.5 feet long, are well-known for their eye-catching indigo-blue hue, which in certain lighting almost seems black.
4. Green Anaconda Green anacondas (Eunectes murinus), though not native to the United States, have been sighted and occasionally captured in the wild, especially in Florida. This is probably because they were released from captivity or managed to escape.
5. Reticulated Python Reticulated pythons are another huge species that have been imported to the United States, much like Burmese pythons. Although they are not as frequent as Burmese pythons.
6. Rock Python Though in extremely small numbers, the African Rock Python, or Rock Python as it is commonly known, has been observed in the United States.
7. Boa Constrictor Another species that is not native to the United States but has made its way into the wild because of the exotic pet trade is the boa constrictors.
