"Imagine you’re a big yellowfin tuna, miles from shore out in the blue,
swimming around carefree, until you start to feel a little itch near your eye.
Maybe it’s just a scratch that’s healing, or maybe it’s a tiny crustacean
nibbling into your skin.
What do you do? You don’t have hands to pick it off. You don’t have cleaner
wrasses nearby to carefully pluck it off for you like you might on a coral
reef.
While poring over thousands of hours of video showing the denizens of the open
ocean going about their lives, we discovered how tunas and other fishes solve
this problem. The answer might be the last thing you’d think of: sharks."
