It is so much more difficult for an octopus to have a “heart break” from love. Keeping aside the growing perplexity of “it’s not working out for us”, the octopus is a complicated sea animal, anatomically speaking.
The octopus has three hearts! There are literally three pumping organs that circulate blood within this mollusk. This is very characteristic of the octopus – Having a closed circulatory system, which means that the blood flows in a contained manner inside blood vessels. The hearts are 2 branchial ones which are located close to the gills (they are like nostrils of our bodies) where they throw out waste material like carbon dioxide. The oxygen filled blood is then moved to the systemic heart which pumps it to the rest of the body including the 8 arms!
Extra Fun Fact:
Moreover, did you know that their blood is blue and not red. This is just because they have hemocyanin which is like Hemoglobin in our blood. The reason it is blue is because it has Copper in it which carries the oxygen and us humans have Iron (which causes our blood to be red).
Extra-Extra Fun Fact:
Takotsubo cardiomyopathy or broken heart syndrome is where the left ventricle, the main pumping chamber of the heart, weakens and causes cardiac problems. The reason for this is likely from mental and emotional stress experienced by the patient. INTERESTINGLY, this term comes from the Japanese pot by which the fishermen used to trap octopuses.
