What would you do if you were kayaking in the open ocean, and a huge whale surfaced right next to you? JUMP IN and film it underwater, right? That's what happened to a kayaker off the coast near Los Angeles, and that's what he decided to do.
Obviously, blue whales don't attack like sharks do. But it's the largest animal on Earth, so they're still dangerous to be around. Luckily, the kayaker didn't get hurt. And he got some great video.
He jumps in the water at 1:09 and 2:11. It comes towards him at 2:15 and goes right by him.
