The Burmese-Indian python DNA snakes are swarming wetlands and forests after the Indian python and Burmese python started breeding in the last 40 years.
Scientists have only now discovered the result of the crossbreeding, and found the new species is capable of both climbing trees and slithering through swamps.
"If some animals die out because of climatic issues, there are other animals that may not die out.
"Our finding that the Florida python population is comprised of distinct lineages suggests greater standing variation for adaptation and the potential for broader areas of suitable habitat in the invaded range," the researchers of the new study said.
The Burmese python is one of the largest species of snake in the world and can reach almost 20ft in length. The largest ones can eat pigs, goats and crocodiles in the wild.
Lighter in colour, the Indian python is usually smaller. However, they too eat mammals.
The researchers found thousands of the new crossbreed has started to emerge in Florida Everglades but we may see populations across the world.
"If the Indian pythons have a wider range, perhaps these Everglades snakes now have that capability," study lead author Margaret Hunter told Miami Herald .
The researchers considered the pythons may have bred in the wild or may have been bred as pets, in a bid to create a species with more appealing colours and patterns, and then returned to the wild.
