Ratonel cannibal behavior, Uraba, Colombia

10 minutes after our guide pulled a Colombian rainbow boa out of the bushes at night, here's comes another snake. An observation we will not soon forget. This is a Ratonel, which is known to feed on any animal it can handle, including other snakes and animals larger than itself.

The idea was to place it on the roadside for a few quick photos, and then place it back. What we could not foresee was that the Ratonel, probably from stress, puked out another snake. And that other snake, is another Ratonel. In this photo you see the underside of the eaten Ratonel, the other side side has the dark red just like the living Ratonel.

So this looks like cannibalistic behavior. I've been searching around but haven't yet found information about this being known behavior, so this could be scientifically relevant.
