A muscular flap called the larynx acts as a gate, sealing the entrance to the trachea when the whale opens its mouth to feed. The short answer is no, they cannot.
Waterproof Lungs and the Hydrodynamic Shape That Prevents Mouth Breathing
Connection to the Lungs An important distinction to understand is the pathway of air. The Evolutionary Adaptation The inability to breathe through the mouth is a direct result of the whale’s evolutionary journey from land to sea.
The spout of water often seen in documentaries is not water being inhaled or expelled from the mouth; it is condensation and spray released from the blowhole as warm, moist air meets the colder atmosphere. Their ancestors were terrestrial creatures with a standard nose-to-lungs configuration.
How a Whale's Hydrodynamic Shape Protects Its Waterproof Lungs
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 evolutionary pressure favored the blowhole design, which offers the most efficient way to breathe while maintaining a hydrodynamic shape for swimming.
