This is a video of a diver allowing a cleaner shrimp to take a peek inside her mouth and pick out any debris it finds. Cleaner shrimp normally do this to fish, removing any parasites as part of their symbiotic relationship. But for a diver? That’s gross. You won’t catch me opening my mouth in the ocean to let any sea life in, that’s for sure. I mean you know whales poop in that water, right? I’m pretty sure it’s like, the only place they poop.
