Biting Off More Than They Can Chew

There is one of these whimsical stories about a Florida alligator and a Burmese python being found locked in a mutually destructive embrace in the Everglades (http://news.bbc.co.uk/1/hi/world/americas/4313978.stm). It seems that the snake, which had lost its head, had tried to swallow the alligator and had burst in the attempt. Of course, the fact that the python is not native to the location (a redundant 'pet'?) may have mean't that it was not skilled in its selection of appropriate prey. Another possibility is that the python, whilst resting with its prey inside it, had its head bitten off by a third predator and the subsequent decay of its muscles led to the bursting of its body.
