Ok. Get this. Here's a python, a big one, eating a mid-sized alligator while the alligator is still alive. Nature is cruel and fascinating!
And if you're wondering if the alligator can gnaw his way out of the snake...well, the answer is yes. Check out the video below of the alligator (possibly a different alligator and python) basically busting through the body of the python. Both die however.
