How do seals breathe underwater? 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.
How do elephant seals breathe? Elephant seals are mammals, meaning that they are warm-blooded, breathe air using lungs, have fur to stay warm, give birth to live young, and nurse their young using milk. Elephant seals also have thick blubber to keep them warm during cold-water migrations.
Do elephant seals have gills? Fish, for example, breathe through gills, but seals don’t have gills. As mammals, they have lungs that require breathing air to replenish the oxygen.
