Bloody penguin battle caught on video goes viral

If you thought it was a tense week for politics, just wait until you see what's happening in the penguin community.

National Geographic posted a graphic new video to Twitter that shows a male penguin returning to his mate -- only to find she's been cuddling up with a new guy.

A vicious, bloody battle breaks out -- and it's unlike anything else you've ever seen in typical penguin-based footage.

Tragically, and unlike many of the animal love stories Hollywood brings us, the female penguin walks away with her man-on-the-side.

You can watch the heartbreaking battle below, but be warned -- it's extremely graphic:

The internet reacted dramatically to the battle, as you would expect.
