How Do Marine Mammals Hold Their Breath For So Long?

The video explores the adaptations of marine mammals that allow them to dive for extended periods. It highlights the role of hemoglobin and myoglobin in oxygen storage and delivery, and how these animals manage carbon dioxide levels. The video also discusses unique adaptations like increased myoglobin surface charge and other physiological changes that enable long dives. Despite these adaptations, humans are unlikely to achieve similar diving capabilities without equipment.

Explain how the carbon dioxide levels in the blood affect the breathing instinct of marine mammals.

What findings were reported in the 2013 study regarding myoglobin in marine mammals compared to land mammals?
