The crab slave sticks his tentacles out of the crab's body for the convenience of his larvae in the future, so that he can parasitize on another crab smoothly. After settling everything, the crab slave begins to grow up, because the crab slave who just entered the crab's body is still a very tiny ephemera, and the crab can't feel the crab slave's larvae.
Crab slave sucks crab gravy. At first, the crab can't feel pain. The crab will feel weak and hungry, just like the feeling of never having enough to eat. In fact, even the meat with nutrition is eaten by the crab slave. The sucking of the crab slave also changes the growth process of the crab. The crab basically won't shell. Every time a normal crab takes off its shell, it means it grows up.
When the crab slave matures, he can directly lay eggs and give birth to larvae, but he has to find a new home for his own larvae. After all, the crab parasitic by the crab slave has entered the countdown of life, and the crab is almost empty, and the gravy is almost gone. When the crab slave matures, it gives birth to larvae, and the larvae still drink crab gravy.
If you don't seize the opportunity, the crab slave larvae will swim with the sea water and find other crabs. The crab slave doesn't worry about finding parasitic crabs, because there are many crabs in the sea, and the crab slave can find crabs by himself when swimming.
In fact, some crabs parasitized by crab slaves are a little different from healthy crabs when viewed from the outside. When crabs parasitized by crab slaves are almost empty shells, they are crooked when walking, which is a bit like the unstable center of gravity and drunkenness, and their bodies are lighter than those of crabs with the same volume. Some crab slaves can be seen directly in the triangle area of crab belly, which is like a ball and yellow, which is different from crab yellow.
How did the crab slave who can control the crab hollow out the crab body?
There is a creature that can turn crabs into zombie crabs. It can not only parasitize crabs to absorb their nutrients and grow up, but also control them to find a mate to mate with crab slaves. Finally, no matter whether male or female crabs are parasitized, they will become "motherly love" like female crabs. This horrible creature is a crab slave that you may eat!
Crab slave: A super cold creature. How did it get into the crab?
Occasionally, something similar to crab roe will be found in the abdomen of the harvested crab, which feels soft, and this part goes deep into the crab. Friends who don't know it thought it might be crab roe cream in the crab breeding season, because it looks quite similar.
Therefore, it is estimated that some people who don't know the truth have eaten this stuff, and I believe it tastes very bad. The crab with this kind of "crab paste" is almost an empty shell, and there is no meat in it, but florists want to tell you that this is the legendary crab slave, which can make people have three layers of goose bumps in the heat of August.
Crab slave absorbs nutrition: there is no bottom line
Once the crab slave enters the crab, the crab can still grow partially in the early stage, but soon with the rapid growth of the crab slave, the crab can no longer provide nutrition for its own growth, so the shelling behavior of the crab will disappear, and the growing crab can't regenerate after its leg is broken. It absorbs almost all the nutrition of the crab!
But the crab is still alive, and the crab slave also needs the crab to live. It is hard to imagine the significance of such a crab living, and I don't know whether it hurts after the crab is parasitic with such a disgusting crab slave.
Such a disgusting creature. How did it get into the crab?
Crab slave is actually a barnacle. There are about 100 kinds of crab slaves in the world. The probability of marine crabs being parasitic is very high, and 20% of Danish fjords are parasitic. Hawaii is as high as 50%, and in some parts of the Mediterranean it is close to 100%. I don't know what the crab slave is doing, because once the crab is parasitic, its reproductive behavior will disappear completely. Isn't this self-extinction?
As barnacles, crab slaves also have a cycle of reproduction, including a stage of plankton. After encountering crabs in the sea, they can inject themselves into crabs. This process is very magical. It is difficult to understand that a tiny larva can break through the hard shell of crabs, so hard that a kitchen knife needs to chop hard to get the big crab shell.
But the larva of the crab slave will find the weakest part of the crab, usually the membrane part of the root of the bristles on the crab's feet, and then the very sharp needle on the larva will pierce the crab, just like an injection, injecting a tiny spot called a parasite into the crab's blood.
After that, it will grow wildly in the crab. In the hepatopancreas, which is the most nutritious crab, it can be clearly seen that the tentacles of the crab slave have reached these positions and surrounded them like a net. It is terrible to think about it.
Crab slave: How does it control crabs to find a mate?
Crab slave has a heinous skill, which is to control crabs, whether it is physical control or mental control, so that crabs have no way out in all directions, but they can serve crab slaves willingly!
Physical control
Once a crab is parasitized by a slave crab, its growth process will destroy the gonad, and the crab can no longer have children. Of course, this is only the beginning, and it will interfere with the growth hormone balance of the crab and its growth and development. Even a male crab can develop into a female. If a female crab is parasitized, it will gradually expand from the genital parts and protrude out of the body when the slave crab is an adult. If a male crab is parasitized, the pointed characteristics of the male crab will gradually expand and move closer to the female crab.
If the crab slave is removed, the female crab will regenerate the ovary, but the male crab will not regenerate the testis, and will also develop the ovary. This is the thorough transformation of the crab body by the crab slave.
Crab slave controls crab reproductive behavior.
If the male crab slave parasitizes the crab, the crab slave will find a higher stone when it matures, then tidy up the swollen pouch in the abdomen, stir the seawater with its claws, and expel the sperm at the same time, while the female crab slave has a similar process, and then these fertilized larvae float on the sea to find the next victim.
Mind control
Physical control needs to be completed through mental control. This crab slave is really terrible. By dissecting the crab parasitized with the crab slave, it can be found that the growth tentacles of the crab slave extend to the brain and nervous system of the crab in addition to the hepatopancreas.
It is difficult to explain that these advanced behaviors of crabs are directly controlled by crab slaves. Biologists believe that crab slaves do not have the skills of cross-species control of crabs at all, and it is incomprehensible for crab slaves to directly control the behaviors of crabs by using the nervous system of crabs. The biggest possibility is to make crabs think that they are in the breeding period and make breeding behaviors belonging to crabs by interfering with their own hormone secretion.
This process is enough to complete the most important reproductive behavior of the crab slave's life, but this parasitism is a little too creepy. The parasitic crab has completely become a zombie crab to complete the breeding of the crab slave, and they are also a major scourge in crab breeding in China and Russia, and the treatment method is simple. Pick it out and destroy it!
There are many magical creatures in the world, some of which live exclusively by parasitism, some of which will have a very great impact on the life of the host, and may even control their behavior. For example, iron nematodes will specially drill into mantis's abdomen, and then they can control mantis's movements. In fact, the crab slave I want to talk about this time can also control the actions of crabs. So how did the crab slave "empty" the crab's body?
New friends remember to pay attention to it, and you can also check more exciting content in the past from my homepage.
People who often eat crabs may encounter such a situation. Some crabs have bulging bellies, and the triangular area of crabs can't be completely closed. It is because there is a yellow substance protruding from the abdomen of crabs, which looks a bit like crab paste. Maybe people who don't know the truth may have eaten these things, but the taste and taste are really bad.
In fact, this yellow substance is a crab slave. However, we should not literally understand this creature. Although it is called "crab slave", it is not a creature dedicated to crabs. If the aquaculture industry meets a crab slave, it is really scared, because once the crab slave parasitizes into the crab, it will soon eat the nutrients in the crab, and then the crab will basically not continue to grow up and even lose the ability to shell. If the crab has a broken leg, they will not be able to regenerate afterwards, and most of the nutrients in the crab will be absorbed by the crab slave.
Although most of the nutrients of the crab were absorbed by the crab slave, the crab was still alive. Because the crab slave can control the action of the crab, the crab can still eat normally, but there will be no such good things for no reason. The crab slave will not do anything useless at all. After eating, the nutrients transformed by the crab slave will be eaten by the crab slave. It should be said that this is the lifestyle after the crab slave parasitizes.
In addition, crabs parasitized by crab slaves will also lose their fertility. However, the influence on crabs of different sexes is particularly great. The abdomen of normal male crabs is mainly triangular, while that of normal female crabs is semi-circular. However, after being parasitized by the crab slave, the male crab's abdomen will gradually turn into a semicircle. If there is a foreign object that can remove the crab slave from the crab, the female crab can still give birth to the ovary, but the male crab can no longer grow its original reproductive organs and will slowly develop the ovary, so the crab slave will transform the crab's body.
Why did the crab slave transform the crab into a female? It is probably related to the nutrients it wants to absorb. Because male crabs only produce crab paste, but not crab yellow, and female crabs are the opposite, it seems that crab slaves prefer to eat crab yellow, which is my simple guess.
Generally speaking, the crab slave won't let the crab die, but the crab slave absorbs the nutrients of the crab for a long time, and the crab is not controlled by itself, which is basically equivalent to a walking corpse. If the crab still has its own feelings, it may really hope to die earlier.
But the crab slave doesn't want the crab to die like this, because the crab slave has been parasitic in the crab for a long time, and his body will grow up, and he will adapt to the empty shell of the crab, so he can't come out again. When the crab dies, the crab slave can't absorb nutrients from it, so his life will basically end here.
When the slave crab is still drifting in the sea, it is just a plankton in the sea. As the sea drifts, once it meets a crab, the slave crab will pay in advance on the crab's body. At this time, it is not a parasitic form, because crabs have a hard shell, which is not easy for crab slaves to break.
After the crab slave is adsorbed on the crab, it will look for the soft part to get in, but no matter where it goes in, it will eventually concentrate on the crab's abdomen. Because the crab's main nutrients are in its abdomen, especially the crab's abdomen will be like a door that can be opened, which also provides space for the growth and development of crab slaves and is a very suitable area for crab slaves.
Now, a straw object like a cylinder will be born on the body, and then it will start to be inserted into the crab's meat, and then it will eat the gravy inside and absorb a lot of nutrients from the crab. Although the crab has two big pliers, it can't deal with the crab slave who has drilled into its body, so it can only let the crab slave run amok.
At first, crabs won't feel anything, but when the nutrients in their bodies are almost absorbed, they will begin to feel weak, and no matter how they eat, they can't eat enough. The meat in the crab will become less and less, but the weight will become heavier. This is all done by the crab slave. Although the crab wants to get rid of it, there is no way.
When the crab slave grows to sexual maturity, it will slowly swell in the crab's abdomen, and then some of it will protrude out of the crab's body. Then it will control the crab to find a higher stone, and then tidy up the baby-rearing bag with swollen abdomen, and stir the seawater with claws, so that the eggs can be fully fertilized.
Crab slave is a hermaphrodite creature, and the fertilization process is relatively less troublesome. It can directly produce larva eggs and give birth to larvae by itself. However, crabs have been occupied by crab slaves, and most of the nutrients in them have been absorbed by crab slaves, so it is impossible to provide them with life. Therefore, during this time, larvae still absorb nutrients from crabs to survive, but crab slaves will help them find a new home.
This mainly depends on the crab slave's ability to control crabs. The slave crab will have many tiny tentacles, which will be used to penetrate into various tissues, nervous system, liver and other parts of the crab. However, scientists believe that the slave crab does not have the ability to control other species. The main reason why the crab is controlled is that the slave crab will disturb the crab and then secrete a hormone, which will make the crab mistakenly think that it is in the breeding period, so the crab will look for a mate, but in fact it is looking for a new home for the larvae.
When the crab is looking for a mate, Xie Nu will take the opportunity to use his tentacles to send the larva to another crab, and then the larva will get a new home. If the larva fails to seize the opportunity, it will be washed away by the sea water and become plankton in the sea water, but it will not die, but the process will be more difficult, and it will be more difficult to find a healthy crab to settle down.
Therefore, the crab thought that it was just the breeding season, but unexpectedly, the crab slave issued an order to harm its companion. So if farmers find this "crab slave disease", they are really scared, because it is likely to infect all crabs, and then the efforts made by farmers are basically in vain.
That's all for this time. If you like it, please give it a big praise!
To sum up, the crab slave is very harmful to crabs. It can parasitize in crabs and then absorb nutrients from crabs, so that crabs' bodies will not grow and develop again, nor will they grow out of their shells, and even their broken limbs will not grow again. What is even more frightening is that crab slaves can control the behavior of crabs and let them find a new home for their descendants. Such behavior is actually harming healthy crabs. Once a crab slave appears in an area, it is likely that all crabs in this area will suffer. What do you think?
