Octopuses have three hearts. Two pump blood to the gills, while one pumps it to the rest of the body?

Octopuses are unique among animals due to their extraordinary cardiovascular system, which includes three hearts. Two of these hearts are dedicated to pumping blood through the gills, where oxygen is absorbed from the water. This blood, rich in oxygen, is then transported to the third heart. The third heart is responsible for circulating the oxygenated blood to the rest of the body, ensuring that the octopus’s tissues receive the necessary oxygen to function.

The blood of an octopus is also remarkable because it contains a copper-based molecule called hemocyanin, which is more efficient than the iron-based hemoglobin in humans when it comes to transporting oxygen in cold and low-oxygen environments. This adaptation is particularly beneficial for octopuses, as they often inhabit deep and cold ocean waters where oxygen levels can be low.

Moreover, the octopus's cardiovascular system can adjust based on its activity level. When an octopus swims, the heart that supplies blood to the body actually stops beating, forcing the octopus to primarily use its gill hearts. This unique system supports their complex behaviors and high intelligence, highlighting the incredible evolutionary adaptations of these cephalopods.

For more details on the physiology of octopuses and their cardiovascular system, you can refer to scientific articles on marine biology and studies on cephalopod anatomy.
