Octopuses have three hearts, which is partly a consequence of having blue blood. Their two peripheral hearts pump blood through the gills, where it picks up oxygen. A central heart then circulates the oxygenated blood to the rest of the body to provide energy for organs and muscles.

Does an octopus have 3 hearts and 9 brains?
The giant Pacific octopus has three hearts, nine brains and blue blood, making reality stranger than fiction. A central brain controls the nervous system. In addition, there is a small brain in each of their eight arms — a cluster of nerve cells that biologists say controls movement.
Can octopus live with 2 hearts?
An octopus with two hearts may be a lot less active than normal, but it will survive. That said, if the octopus loses its systemic heart, which pumps blood around the body, it is as good as dead.
Do all octopus have 8 hearts?
Octopuses have 3 hearts, because two pump blood to the gills and a larger heart circulates blood to the rest of the body. Octopuses have 9 brains because, in addition to the central brain, each of 8 arms has a mini-brain that allows it to act independently.
Why do octopi have 3 hearts?
2) Octopuses have three hearts. Two of the hearts work exclusively to move blood beyond the animal’s gills, while the third keeps circulation flowing for the organs. The organ heart actually stops beating when the octopus swims, explaining the species’ penchant for crawling rather than swimming, which exhausts them.

The animal with eight hearts is Barosaurus.
Having eight hearts means that a lot of pressure is required for blood circulation in the body.

Are octopuses 8 brains?
In addition to a central brain located between the eyes, octopuses have separate “mini-brains” at the base of each of their eight tentacles. Unlike most creatures, octopuses have nine brains, and they put them to incredibly adept use.

Does an octopus feel pain?
