My mom gave me this article from a newspaper that someone gave to her for me to read. This is what it says:

In a case of real life imitating Hollywood, the U.S. scientific community is increasingly concerned that two non-native python breeds currently slithering free in southern Florida could morph into a giant man-eating swamp coil.
The capture of five African rock pythons recently near an Everglades already teeming with the gentler Burmese pythons has scientists worried about so-called hybrid vigor - a phenomenon that occurs when interbreeding uncorks volatile recessive genes, passing traits such as aggression onto the offspring.
Think Africanized bees. The two species have interbred in captivity. While Burmese pythons aren't known to eat people in their native habitat, the African rock python, unfortunately, has been known to do just that.

Thought I'd share this with you guys.
