If the octopus's central heart is damaged, the octopus dies. An octopus's situation is as if those four chambers were divided into two hearts, and then one of those was made redundant. Two of the hearts work exclusively to move blood beyond the animal’s gills, while the third keeps circulation flowing for the organs. Hemocyanin is less efficient that hemoglobin in regular conditions, but it is much more efficient at transporting oxygen in cold conditions and under low oxygen pressure than hemoglobin. Our own human hearts are divided into four chambers. Hemocyanin lacks iron, which makes human blood red, which means that the blood of an octopus is actually colorless and turns blue when exposed to air. Unlike many animals, the blood of an octopus contains the protein hemocyanin, instead of hemoglobin, for transporting oxygen. Many people believe that the blood of an octopus is blue. These two branchial hearts support the main heart, known as a systemic heart, which pumps oxygenated blood through the rest of the body. Two of these hearts are known as branchial heart, which are located at the base of the gills, and pump the blood through each of the octopuses gills. Yes, there are four-chambered hearts, as in mammals, three-chambered, like amphibians, or in general one-chamber (fish) hearts. Although these species have some differences, all octopuses have the same number of hearts.Īn octopus has three hearts. As many as three None of the representatives of mammals, amphibians or birds have such a phenomenon. There are approximately 300 different species of octopuses and they can be found throughout most of the world ocean’s. They are classified as a cephalopod, along with the squid and cuttlefish. One of them is the "body heart", which plays a major role in blood supply to the octopus's whole body There are two "gill heart", they can also play a part of the role of blood supply, but their main role is not to supply blood, but to filter the waste produced by the body, from this description can be seen that the gill heart is more like the role of human kidney.An octopus is a marine animal best known for their flexibility, and 8 arms that usually have a number of suction cups. Use this answer in My Telenor app quiz questions. In addition to having nine brains, an octopus also has three hearts. How many hearts does an Octopus have Here I provided the correct answer to this question for Wednesday. How many hearts does an octopus haveĪs mentioned above, the structure of an octopus is very special. Therefore, it can be said that these eight accessory brains play the role of memory and do not play the role of thinking. The main role of the accessory brain is memory, and these eight accessory brains are connected to another memory system. Octopuses have their parencephalon in the place of their tentacles, and they have eight tentacles, so they have eight parencephalons. The main brain has two main functions, one is thinking, the main brain is relatively developed, making the octopus IQ is relatively high The other is memory, because the brain is connected to a memory system. Among them, the main brain is the most important one, located in the head of octopus. The functions and importance of these nine brains are different, which can also be seen from their names. Humans and most other animals have only one brain, but octopuses have one main brain and eight accessory brain systems, that is to say, octopuses have nine brains. Another big difference is the number of brains they have. Their heart, memory system and so on are different from most animals. The structure of octopuses is different from that of most vertebrates, because they belong to invertebrates. The other eight cerebrums are located on their eight tentacles and are connected to another memory system.

The master brain, the most important brain, is located in the head of the octopus, and it is connected to a memory system, which plays a role in memory and thinking. Most animals have only one brain, but octopuses have nine brains, one of which is the main brain and the other eight are the secondary brain.
