Comment 1 by Misfire :

I've been curious about animals that can survive in both deep and shallow water. Is it only air which would expand or contract when an animal moves up or down? If a person drowned, their lungs filled with water, and they sank a few thousand meters, would they be crushed?

No. Ambient water pressure (like air pressure) is uniformly distributed - unlike, say, the bilateral crushing force of a vise. Also, fleshy bodies are mostly liquid and therefore incompressible.

I assume when deep-sea critters are brought to the surface and “explode,” there’s some expansion of internal gases going on.
