Since I just got BACK from the beach, this footage is well timed for me or otherwise, we'd have had our vacation elsewhere...By the way, SHARK WEEK starts soon!!
Last year, scientists used a small, remote-control submarine with a bunch of cameras on it to get close-up footage of great white sharks off the coast of Mexico. And I'm sure they collected all kinds of useful data.
But for OUR purposes, the video is cool because a great white ended up ATTACKING the sub, which was basically the same shape as a human leg. So the video is essentially what it would look like if a shark started chowing down on YOUR leg.
