CATDOLL : CATDOLL: How big can an octopus grow and how big can it reproduce?

How big can an octopus grow and how big can it reproduce?

The size of an octopus is not fixed, because there are many different species. According to statistics, there are more than 600 species of octopuses distributed around the world. There are some relatively small octopuses, such as the "arborescent octopus", whose adult body length is only about 5 cm. There are also relatively large octopuses, such as the "Pacific octopus", which can reach a radius of 7.8 meters after their tentacles are stretched out when they are adults, and weigh more than 50 kilograms. 1. How big can an octopus grow? The octopus is a mollusk that lives in the ocean. The size of an octopus is not fixed, because there are many species of octopuses themselves, and there are probably more than 600 species of octopuses distributed around the world. Although these different species all belong to the large category of octopuses, the differences between them are still relatively large, such as in terms of body size. The differences between them are relatively large.

The size of some species of octopuses is not fixed. For example, the species "arborescent octopus" has relatively small individuals, and their body length after adulthood is only 5 cm; of course, there are slightly larger individuals, but generally not very large. Some species of octopuses can be very large, such as the "Pacific octopus". There was once a record of a very large Pacific octopus. After their tentacles were fully extended, their radius could reach 7.8 meters; they also weighed very heavy, reaching more than 50 kilograms. It can be seen that how big an octopus can grow is affected by genes.

2. How old can an octopus reproduce? As mentioned above, there are many different species of octopuses, and the reproduction characteristics of different species of octopuses are also different. Generally speaking, they can reproduce after they become adults. When octopuses reach the right age, they will reproduce in the appropriate breeding season. Generally speaking, their breeding season is in spring and autumn, that is, when the seawater temperature is moderate. After studying the reproduction process of octopuses, some researchers found that some octopuses may only reproduce once in their lifetime, and then they will die.

Why do octopuses reproduce by suicide? They could dominate the ocean, but die young?

Some scientists have confirmed that the nerve impulses of the octopus's "optic gland" cause female octopuses to reproduce in suicide. According to this theoretical point of view, scientists have found that after mating, female octopuses regulate cholesterol metabolism, insulin and steroids, etc., and begin to increase their secretion, which triggers their tendency to look at eggs, and finally ends with extreme behavior and suicide reproduction.

Although octopuses are very intelligent, they can only reproduce once before they die.

Octopuses have very high IQs. They have nine brains and three hearts. Their eyes are very similar to those of humans, including the same retina, lens and iris. They can receive external information through vision and make reasonable judgments based on the information. Octopuses even have very strong hearing abilities and can hear sounds a hundred kilometers away.

For such an intelligent creature, it has surprising behavior, even incredible. It reproduces only once in its lifetime, which means it only reproduces once before it dies. This may not be the first time that octopuses have used this method of death reproduction. Salmon also have a reproduction method where the end of spawning means the end of life, but this behavior in octopuses is incredible.

Unmated female octopuses are active and agile hunters in the ocean, but after mating they become listless until the end of their lives

Unmated female octopuses are very active. As agile hunters in the ocean, they often go out of their nests to hunt, which makes them much more "hardworking" than male octopuses. However, once a female octopus mates, the nerve impulses in the "optic gland" will cause extreme maternal behavior, and she will starve herself to death in order to take care of her eggs in the nest. After mating, female octopuses not only become listless, but also stop actively hunting, and only "attack" passing small fish and shrimps to maintain their food intake for about 4 days.

In the next 8-10 days, the female octopus will completely stop eating, and when she is too hungry to bear it, she will eat her own tentacles to resist. The female octopus takes about a month to incubate the eggs, which means that the female octopus's life will end before the eggs are fully hatched or not long after they are hatched. This extreme suicide hatching method is caused by the increase in the secretion of steroids and insulin-like factors in the female octopus' body, which stimulates the extreme tendency to watch the eggs.

Female octopuses commit suicide to avoid eating their own eggs and protect their young

The female octopus's suicide reproduction method has gradually attracted the attention of many scientists. According to scientists' in-depth research, the female octopus's suicide reproduction method is only to avoid accidentally eating its own eggs. As we all know, octopuses are highly carnivorous creatures. They will also prey on their own kind during the hunting process. Assuming that the female octopus does not reproduce by suicide, it may accidentally eat its own eggs during the hunting process, which breaks the natural rules of reproduction in nature.

For this reason, female octopuses adopt suicide reproduction. On the one hand, they can protect their young and avoid being eaten by others. On the other hand, the death of female octopuses can save marine food, which is convenient for young to eat and survive efficiently. Of course, during mating, male octopuses will also remove the tentacles and abdominal segments on their mating arms to ensure the success rate of fertilization, which will eventually lead to mental exhaustion and death.

In short, octopuses reproduce by suicide in order to ensure the efficient survival of their offspring and maintain the ecological balance of the ocean. Everyone can fully understand that whether it is animals or humans, in many cases, the sacrifices made for the healthy growth of the next generation are huge.

The octopus's suicide reproduction method is a natural selection of the species and cannot be changed. It is caused by genetic elements.

This is because this is the nature of octopuses, but this method of reproduction is really very strange.

Because the octopus's nerve impulses cause the female octopus to reproduce in a suicidal way. At the same time, they also have no ability to take care of their eggs, so they cannot dominate the ocean.

No one knows why this happens, and there are still many things we don't understand about this "ocean celebrity", but there are several speculations! Octopuses, like many animals in the ocean, have weaker species on their menus, and highly carnivorous octopuses often prey on their own species, so this suicidal behavior may be a way for mothers to prevent themselves from eating their own young.
