Octopuses have three hearts and blue blood. Two of the hearts pump blood to the gills, where it is oxygenated, and the third heart pumps the oxygenated blood to the rest of the body. Their blood is blue because it contains a copper-rich protein called hemocyanin, which is more efficient than hemoglobin (found in humans) at transporting oxygen in cold and low-oxygen environments, like the deep sea where many octopuses live.
