Ocean the Majesty on Instagram: "Do you know what color octopus blood is? 🐙🎨 Octopuses have blue blood due to a copper-rich protein called hemocyanin, which efficiently transports oxygen in cold, low-oxygen environments. To support this system, they possess three hearts: two pump blood through the gills, and one circulates it to the rest of the body. These intelligent creatures can change their skin color and texture to blend into their surroundings, solve puzzles, and even open jars. When thr

An octopus has three hearts and blue blood — and there’s a fascinating reason why. Instead of iron like humans, octopus blood uses copper to carry oxygen. That’s what makes it blue. But copper is much less efficient at transporting oxygen. So to move enough oxygen through their bodies, octopuses evolved three hearts. Two hearts pump blood to the gills to pick up oxygen, and the third pumps it to the rest of the body. But when an octopus swims, its body movement puts so much strain on circulation
