Why do octopuses reproduce by suicide?

2021-01-07 | Weird Rokop Original |

With the development of society, more and more people position themselves as DINK, they do not have their own children, except for a small number of infertility, most of them do not want children for various reasons.

Although everyone's reasons are different, but in the final analysis: As a parent, you need to sacrifice a lot for your child, not necessarily in return.

In the animal world, most parents are the same as us and need to pay a lot for the next generation, but some are extreme, they completely give up their lives.

For example, octopus, taking care of your first baby is the last thing for female octopus.

When a female octopus begins to reproduce and lays its own eggs, it will stop preying and hide the eggs under its own body like a hen, which makes it starve to death before the cubs hatch.

Octopus has always been the darling of the Internet, different from ordinary people's IQ, nine brains and three hearts, looks exactly like aliens, which makes it attract countless fans on the Internet.

It can be said that no animal does not play cards like an octopus. Some of the most serious academic studies even directly believe that they are from aliens.

Do octopuses really reproduce by suicide?

First of all, let's get to know the octopus, in fact, it is not necessarily the octopus that has tentacles.

The picture above perfectly explains several creatures that we often call octopuses. Only this kind of eight-legged octopus is an octopus, and the high IQ players we usually talk about are those eight-legged guys.

Although octopuses are smart, they are indeed a one-time reproduction creature, which means that they only reproduce once before they die.

But they are not special existence on the earth. I have seen many people holding this point and said that octopuses are from extraterrestrials. In fact, many creatures that reproduce like octopuses can be found on earth, such as salmon, spawningThe end is the end of life.

Octopuses have their own nests, and unmated female octopuses are very active and are agile hunters in the ocean. They spend a lot of time out of the nest to hunt.

However, after mating and laying eggs, female octopuses will be stimulated "motherhood", they will stay in the nest to look after their eggs, and often blow water on the eggs. At this time, they will not take the initiative to attack, but passing bySmall fishes and shrimps will still be eaten by them, and this state will last for 3-4 days.

After this, they started to go on a hunger strike completely. Due to lack of energy intake, they became listless, and the small fishes and shrimps passing by were gone. This state will last for 8-10 days.

Afterwards, they will become restless, pale and weak, and sometimes eat their own tentacles. It may take more than a month to hatch. Not long after the baby octopus hatches or has not hatched, the life of the female octopus isended.

The scientific explanation is that the "optic gland" nerve impulse of the octopus creates the suicidal reproductive mode of the female octopus.

After mating, the secretion of catecholamines, steroids that regulate cholesterol metabolism and insulin-like factors in female octopuses began to increase, which stimulated their tendency to look after their eggs, but it was too extreme.

But interestingly, male octopuses will die soon after mating, but they are not under pressure to take care of the eggs. This is still a mystery.

But why do octopuses do this? Many people think that octopuses are so smart. If they have enough time to study, they may dominate the ocean, but they "die young".

The cause of death of octopus after mating!

To be honest, no one knows why this is the case. We still have too many things to understand about this "ocean internet celebrity", but there are several guesses!

Octopuses are like many animals in the ocean. They have weak and small species in their diets. Highly carnivorous octopuses often prey on the same species, so this suicidal behavior may be a way to prevent mothers from eating their cubs.

In addition, octopuses can grow indefinitely, so eliminating hungry adult octopuses can prevent the octopus ecosystem from being controlled by a few large and weird octopuses.

If they die after they don’t mate, the octopus grows in a way that the consequences are predictable. The strength gets bigger and bigger. In the end, only these genes will be inherited and they will not be able to cope with the complex environmental changes.


Of course, this is all understood from our human perspective. Perhaps octopuses cannot understand why humans reproduce so many times in their lives!

If we look at the problem from another angle, the problem will become simple and clear. The whole purpose of life is to transfer genes. Every species has found the most suitable way to transfer genes.
