Unlike humans, harbor seals breathe out before diving. They use oxygen already in their blood and muscles while under water, and their heartbeat slows from about 100 beats per minute to 10. In one breath a seal can exchange 90% of the air in its lungs. Humans can only change 20% of our air per breath.
