One of the most fascinating features of octopuses is that they possess three hearts. Two of these hearts are responsible for pumping blood to the gills, while the third heart pumps blood to the rest of the body. When an octopus swims, the heart that delivers blood to the body actually stops beating, which is why octopuses prefer crawling rather than swimming, as it is less tiring for them. This unique circulatory system helps the octopus manage its complex body functions efficiently in its aquatic environment.
The Role of the Three Hearts in Octopus Biology
The three-heart system is crucial for an octopus’s survival, particularly in its deep-sea habitats. The blood of octopuses is copper-based, unlike the iron-based blood in humans, and this allows them to survive in low-oxygen environments. This adaptation is perfect for an animal that spends much of its time in the ocean's depths. Additionally, the unique heart structure and blood circulation help octopuses manage the energy needed for their extraordinary agility and intelligence. This biological feature supports their ability to be expert hunters, problem solvers, and escape artists. Shutdown123
