A 13-foot (4-meter) Burmese python in Florida’s Everglades National Park explodes after making a meal out of a gator – literally, leaving everyone baffled as to what exactly happened.

Wildlife researchers in South Florida Natural Resources Center found the dead python after it apparently tried to digest a 6-foot-long (2-meter-long) American alligator. The mostly intact dead gator was found sticking out of a hole in the midsection of the python, and wads of gator skin were found in the snake’s gastrointestinal tract.

For whatever reason, the head was also missing from the python when it was found, making this scenario even stranger than it already is.
