I think some of these fish would straight up explode too if you rapidly changed the pressure at sea level vs the pressure at 1500-4000 feet. But change the pressure incrementally, I think they'd be intact above water.

It's not due to incremental changes, it's because the pressure is equalized. So the wreck of the Titanic has significant water pressure on it, but it's from all sides so there's no real force being exerted on it. Whereas a sub that has air in it has a massive pressure differential between the interior and exterior that the hull needs to withstand.
