If you've never seen a whale up close, it's one of the coolest things ever. I went on a whale-watching trip last summer in Cape Cod and would recommend it to everyone.

What I wouldn't recommend is diving so close to whales that they almost eat you.

When you're on a whale-watching trip, the first thing they tell you is to look for lots of bubbles and tiny fish (i.e. whale food.)

The hungry whales create the bubbles to scare the fish, the fish then swarm together for safety in numbers, but instead just give the whale a big, convenient mouthful of food.

These divers off the coast of California probably knew as soon as they saw the bubbles and the massive school of fish what was coming next, but at that point, there's not a lot you can do other than try to not get swallowed!

Luckiest guys on the planet? Most daring? Dumbest? No matter what, they have an amazing story to tell!
