An octopus has three hearts. Two of the hearts pump blood through the gills, while the third heart pumps oxygenated blood throughout the rest of the body.
An octopus has one systemic heart responsible for pumping blood throughout the body, and two branchial hearts that pump blood through the gills. This unique cardiovascular system helps the octopus maintain efficient oxygenation in its body, aiding in its complex marine lifestyle.
