New study provides more insight into the physiology of elite divers

If the Olympics allowed marine mammals to compete, they would dominate free diving competitions in terms of breath holding duration and extreme physiology. Marine mammals also have adaptations that help prevent tissue damage from the lack of oxygen during such dives. For example, Weddell and northern elephant seals store large amounts of oxygen in their blood and muscles, thanks to abundant hemoglobin, which permits them to hold their breath for […]
