Question
An aquatic organism needs to be neutrally buoyant
to stay at a constant depth. Fish accomplish this
with an internal swim bladder they can fill with air
that they take in from the water through their gills.
One complication is that the pressure in the swim
bladder matches that of the surrounding water, but
the water pressure changes with depth. Because
the volume of a gas is inversely proportional to
pressure (as you may already know if you have
studied the ideal-gas law), the volume of air in a
fish's swim bladder decreases with depth unless
the fish actively adds more air.
