A key adaptation is the presence of high concentrations of myoglobin in their muscles. Fish utilize gills—feathery, vascularized organs that extract dissolved oxygen directly from water as it passes over them.

The Diving Reflex and Energy Conservation Whales are masters of energy conservation, a necessity for survival in the pelagic zone where food can be scarce. Blood flow is carefully redirected to the brain and heart, ensuring that vital organs remain functional even when the lungs are empty.
Whales, being mammals, inherited a terrestrial respiratory system that relies on lungs. The blow is the visible mist expelled when they force out the carbon dioxide-rich air and inhale fresh oxygen in a fraction of a second.

Furthermore, their blood exhibits a higher concentration of red blood cells and hemoglobin, maximizing the oxygen-carrying capacity. Understanding the distinction between true gills and these modified respiratory structures is essential to appreciating how marine megafauna thrive in an environment where oxygen is scarce.
