How Many Hearts Does an Octopus Have?
Originally, octopuses had only two hearts, but later, they evolved to have three. These heart-like structures give them more pressure and oxygen. All three of them work together, providing the octopus with enough blood pressure and oxygen to keep it alive. Its blood is thick and blue, so it is important to know how each of them functions. You can find out more about this interesting creature by reading this article.
octopus has three hearts
The octopus has three different hearts. Two pump blood to the gills, and one circulates blood throughout the rest of the animal’s body. In addition, the octopus has intricately-built eyes. Despite their multiple hearts, octopuses are considered the fastest, largest, and smartest invertebrates. Some species are even known to play with toys, which are sometimes called octopuses.
The Octopus Has Three Hearts is a debut short-fiction collection by Vancouver poet and memoirist Rachel Rose. Like many other literary short-fiction collections, this collection explores issues of sexuality, identity, and fidelity. Readers who are drawn to animal-themed works, literary fiction, and memoir will find The Octopus Has Three Hearts an enjoyable read. But before you buy it, take a moment to learn about its author.
It has two branchial hearts
The branchial hearts of an octopus act as additional pumps that take some of the strain off of the systemic heart. Even with two hearts, the main heart still works hard, but in a less-active state. In addition, active swimming in octopuses causes the main heart to shut down, so these creatures generally prefer to float, crawl, or chill out. An octopus’s two branchial hearts can be found in the abdomen of some species, and the disease is called Takotsubo cardiomyopathy, from the name of the pot that traps them.
The hemocyanin, a copper-containing protein, circulates oxygenated blood throughout an octopus’s body. Just as humans’ blood is composed of hemoglobin, octopus’s blood is thick and complex, requiring additional energy to push it through its body. The hemocyanin protein in octopus blood is unlike the hemoglobin protein in humans and is also much larger.
It has nine brains
The octopus has nine brains, making it the most intelligent invertebrate on the planet. In addition to the central brain, the arms have brains of their own, but they do not act independently. They work in conjunction with the central brain, coordinating all their actions. Researchers studied common Mediterranean octopuses to study the brains of individual arms. The researchers found that the arms were not capable of sending sensory information without the help of the central brain.
Despite the lack of common anatomy, octopus brains share several cognitive features with vertebrates, including long-term memory and versions of sleep. In addition to memory, octopuses are capable of recognizing people and objects and exploring objects with play. This ability to distinguish between individuals may have contributed to the octopus’s incredible versatility. And the octopus’s nine brains do not just support memory; they also allow it to act in self-control, which is crucial for avoiding danger.
