When a whale submerges itself it releases air from its air bladder causing its overall density to increase.  At the point where its density is > than the density of the water, it will sink.  As it sinks the surrounding pressure increases but due to its higher density it can withstand the pressure - up to a point at least.  At some point it must make an effort to move upward to breathe as well as avoid sinking to a depth at which the pressure becomes too high and crushes it.

Not the best explanation I'm sure but hopefully you get the idea.

It is density to simplify it.
