An animal’s three hearts have different roles. Octopuses are the only animals known to use their hearts to breathe, and they do so in a way that is similar to that of humans. Their lungs are filled with air, which they expel through their gill openings. The air is then pumped back into the lungs through a tube called the trachea. This is the same tube that humans use to inhale and exhale air.
