Octopus is the only creature in the world which has 3 hearts and 9 brains. You will be surprised to know that all three hearts look different. Their works are also different. A heart is called systemic, which pumps blood to the entire body and legs. Whereas the second and third are known as branchial. Its function is to collect deoxygenated blood from the entire body and send it to the systemic heart. Due to this, oxygenated blood again flows in the body. Due to the presence of hemocyanin (protein) in the blood cells, their color is not red but blue.
