Dolphins breathe air through their blowhole, which is located on the top of their head. When they come to the surface of the water, they voluntarily open their blowhole and exhale, producing a distinctive spray or mist. They then inhale fresh air into their lungs before submerging again. Dolphins are voluntary breathers, meaning they must think to inhale and exhale, unlike humans who breathe involuntarily. This allows them to remain underwater for several minutes at a time before returning to the surface to take another breath.
