Our ability to hold our breath for long periods of time is a critical aspect of marine mammals’ survival. While humans and other terrestrial mammals typically breathe in and out about 12 times per minute, marine mammals can hold their breath for much longer durations. For example, contacted killer whales can stay underwater for up to two hours, and Weddell seals have been recorded holding their breath for up to 80 minutes.

One might think that maintaining such low rates of breathing would result in a lack of oxygen to the brain, and potential brain damage. However, marine mammals have a number of physiological adaptations that allow them to remain submerged for extended periods without suffering from brain damage.

First, marine mammals have large lungs relative to their body size. This allows them to take in more oxygen when they do breathe, and minimizes the amount of off-gassing of carbon dioxide that takes place. Second, their myoglobin levels are high. Myoglobin is an oxygen-binding protein found in muscle tissue, and its presence allows marine mammals to store oxygen in their muscles.

Finally, marine mammals have a high density of capillaries in their brain. Capillaries are the smallest of blood vessels, and their presence allows for better oxygenation of brain tissue. Together, these adaptations allow marine mammals to remain submerged for long periods of time without suffering from brain damage.

While the exact mechanisms are still being studied, it is clear that marine mammals have a number of adaptations that allow them to avoid brain damage when they swim. Their large lungs, high myoglobin levels, and dense capillary networks all work together to keep their brains oxygenated, even when they are barely breathing. As we continue to learn more about these amazing creatures, we will only be more impressed by their abilities to thrive in the marine environment.
