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.You learn something new every day what did you learn today? In addition to having nine brains, an octopus also has three hearts. 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.
