Part 2: Oxygen Storage When an aquatic mammal begins to dive, it actually exhales and pushes oxygen out of its lungs. This decreases its buoyancy so it doesn't have to use as much energy to fight the tendency to rise to the surface. So, how can these animals stay under for so long if they aren't "holding their breath?" Observe the following graphs. Compare where the 3 animals (2 mammals and 1 bird) store their oxygen.
