Not a fact but a question:
How do whales keep water out of their anuses when they are deep diving?
Whales have been known to dive almost 2 miles deep and at that depth you're looking at almost 300 atmospheres of pressure and a whale's sphincter has to be strong enough to resist that.
They don't. That's their kink.
Same.
I had to look it up out of curiosity. The rib cage and lungs of sperm whales are adapted to collapse under pressure, squeezing all the air the lungs into a small space and increasing internal cavity pressure.

I think that also happens to humans, but without being adapted to it, it's a one way squeeze.
Like a tube of toothpaste
Not as minty
Depends what you eat.
Wait, why didn't they get the bends?
They know to ascend slowly to avoid it, but it can absolutely happen.
