In conclusion, the octopus survives even though the circulatory system is so complex that the whole body's heart can stop beating for a few seconds (or, as the Smithsonian says, the entire time of swimming). Seems impossible if one of their hearts stops (forever).
Can an octopus live with one heart?
If you lose one and the main heart, the octopus can pump blood and oxygen to one heart, but not the rest of the body. An octopus dies if it loses two hearts and cannot live on one heart alone.
What if the octopus loses its heart?
But if the octopus's whole body heart fails, that's bad news. The octopus is the heart that supplies blood to the whole body and also helps to supply important oxygen around the body, so it cannot survive. 5окт. 2018
Do octopuses need all three hearts?
Octopus is a cephalopod, literally meaning "cephalopod", representing a truncated anatomy. Like the other three members of the group (squid, squid, nautilus), it has blue blood because it uses a copper-rich protein to transport oxygen. This helps explain why you need three hearts.
Why do octopuses need three hearts?
2) The octopus has three hearts. Two of the hearts function only to move blood across the gills of the animal, and the third maintains circulation in the organs. When the octopus swims, the heart of the organ actually stops beating and is a description of the species that prefers to crawl rather than swim, which makes them tired.
