Sharks are by far one of the most feared predators in the sea. They eat almost anything that comes their way, and they aren't particularly picky about their diet. They've been known to feast on people, whales, and even other sharks.
However, sharks usually prey on seals. Seals are unsuspecting and slow enough to make them easy targets for the fearsome predators. Not this seal, though. He has some epic evasive maneuvers to avoid being eaten and leave the shark in its dust.
If only all seals had those kind of moves, we would have a lot more of them in the world. I bet that shark feels really silly now. He thought he was going to have an easy snack, but it narrowly escaped his jaws.
