This is the footage of a napping great white shark captured for the first time ever by a robotic submersible. Apparently great white sharks nap-swim against the current with their mouths open. You know the nice thing about being a great white shark is? You don't have to worry about running into anything more dangerous than yourself when you're nap-swimming. Merpeople aren't so lucky. I heard one of Ariel's sister's boyfriends nap-swam straight up a whale's butthole and has never been seen again.
Keep going for the video.
Thanks to Jacky, who agrees it's not polite to film anybody while they're sleeping without their consent. Preferably written.
