This has been big news - no pun intended. A hungry python in outback Queensland, Australia, took on a freshwater crocodile and won. Tiffany Corlis happened to be nearby with her camera and took an astonishing series of photos documenting the 5 hour battle and its eventual end. The best photos of what happened I could find are here in this slideshow.
I knew constrictor snakes could swallow large prey due to their ability to stretch their jaws apart but I still find this extraordinary. The snake, according to some reports, was about three and a half metres in length and judging from the photos that makes the crocodile at least 2 metres. Impressive by any standard.
