Why do whales surface to exhale, and when do they inhale?
Exhaling under water decreases buoyancy. Try it next time you're at a pool – humans generally float with full lungs but sink after fully exhaling. Exhaling *before* surfacing makes it more difficult to surface.
The Short Answer
Exhaling under water decreases buoyancy. Try it next time you're at a pool – humans generally float with full lungs but sink after fully exhaling. Exhaling *before* surfacing makes it more difficult to surface.
