Octopus is a mollusk with a small body and eight long and thin tentacles, which is why it is called Octopus.
For octopus, besides octopus, it is also called octopus.
Octopus has strong self-defense and offensive ability, and many small marine animals are afraid of it.
Octopus is very sensitive because its nervous system is divided into central nervous system and peripheral nervous system. There are also auditory, olfactory and visual nerves in its cerebral ganglia, and the most powerful of these is vision. And its olfactory organ is very strange, growing in the small nest of the skin behind the eyes.
Octopus's wrist-touching sensitivity is very strong, comparable to human arms, but there are not two, and others have eight. This is not because Octopus never stops dancing when touching his wrist while sleeping, and always keeps ready for war. Octopus can spray ink six times in a row, and it has a strong ability to save money. It can be sprayed again half an hour after spraying, but don't worry, Octopus's ink is harmless to us humans.
Octopus also has the ability to change color. It will change color when he is excited, afraid, and so on. It is the eyes and brain that command it to change color. If there is something wrong with one side of the command system, then he can only change color at the same time, which is very similar to our human hemiplegia.
More amazing than discoloration is that after the octopus's wrist is broken, it will not bleed, and a new wrist will grow the next day.
What moved me most was that Octopus can only be born once in its life. Every time after mating, the male Octopus will die a week later, while the female Octopus will also die from overwork when it hatches the young Octopus.
Finally, I will not talk about its nutritional value. Octopus contains nutrients such as protein, fat, carbohydrate, thiamine, riboflavin, niacin, vitamin E, calcium, phosphorus, potassium, sodium, magnesium, iron, zinc, selenium and copper. And eating it can replenish qi and blood and resist aging.
