Their ancestors were terrestrial creatures with a standard nose-to-lungs configuration. While the mouth is used for feeding, it is not connected to the respiratory system in a way that allows for breathing, as doing so would lead to fatal choking.

Furthermore, while some animals, like sea snakes, can exchange gases through their skin or mouths to a limited degree, whales lack this capability. They are not able to breathe autonomously like humans while sleeping.
The throat grooves and baleen plates of filter-feeding whales help expel water efficiently, but the actual act of breathing requires the precise timing of the blowhole opening after the mouth closes. This sophisticated separation ensures that water never enters the lungs and that oxygen intake is strictly managed through the blowhole.

Among the most persistent questions regarding marine mammals is whether whales can breathe through their mouths. This evolutionary pressure favored the blowhole design, which offers the most efficient way to breathe while maintaining a hydrodynamic shape for swimming.
