Where does the air go? Anatomy and functions of the respiratory tract in the humpback whale (Megaptera novaeangliae)

Air is a limited resource under water. Pressure changes during diving and ascent further affect buoyancy and sound production/transmission by changing air volumes, densities, and shapes of air spaces and vibration pathways. This paper will focus on how humpback whales use air, and the respiratory tr...
