Dolphins are air-breathing, aquatic mammals, and live in the sea, though certain species live in rivers and estuaries.
Most fish always have to stay in water. Dolphins come up to the ocean surface for a breath of hair. Dolphins breathe through their blowhole.
Dolphins have lungs like humans for breathing, but their respiratory system is adapted for living in water. They have a larger and more efficient airway system, as well as the ability to shut off one half of their brain while resting to ensure they continue to breathe while unconscious.
