What kind of creature is a crab slave?

In fact, there are quite a few people who have seen crab slaves but don't know it, you pay attention to the abdomen of crabs, that piece of yellow thing is crab slaves, and people often confuse crab slaves with crabs, after all, they do look very similar.

The crab slave is a parasitic creature, similar to the common barnacles on ships and oysters, but the crab slave is much more ruthless than the barnacles, after all, the barnacles and oysters are only a mutually beneficial symbiotic relationship, and the crab slave parasitizes the crab and wants the crab's life.

Crab slave grows in seawater, after the crab slave hatches, it will absorb the leg of the male crab, and after a period of time, after completing the first shelling, it will find a gap in the leg joint of the male crab and enter the body of the male crab, and reach out like an octopus-like tentacle to firmly grasp the meat of the male crab, absorbing the nutrients in the crab's body. In addition to stealing nutrients from male crabs, crab slaves can also manipulate the growth of male crabs, affecting the hormone secretion of crabs, making the male crab's belly stretched very long.

When the nutrients of the male crab are almost absorbed by the crab slave, the crab slave completely occupies the dominance of the male crab, and the male crab is like a puppet controlled by the crab slave, completely losing his self-consciousness and being called by the crab slave.

The crab slave parasitic on the female crab will control the female crab to mate with the male crab, and after the mating is completed, the female crab will climb to a high place to lay eggs, in fact, this is also a full set of crab slaves, the female crab will physiologically stir the eggs in the abdomen when laying eggs, and the crab slave will rely on the habit of the female crab to let the female crab help him stir the eggs, that scene is too weird, the crab slave is really not tired at all from daily eating and drinking to laying eggs.

Once the crab is parasitized by the crab slave, it is not far from death, generally about two weeks The nutrients of the crab will be sucked dry by the crab slave, so many farmers once they find that there are crabs parasitized to take measures as soon as possible, the sick crab needs to be isolated from the normal crab, and the sick crab can be effectively inhibited by zinc sulfate, and the salinity of the farm water can also play a certain role.

A parasitic organism that is quite large and has a mutually beneficial relationship with barnacle oysters, this crab is very agile.

Parasites, which cause the death of the crab and cause a lot of harm to the crab.

It is a parasitic organism that will parasitize inside the crab and eat some of the things inside the crab.

The crab slave is a hermit creature that usually appears in the abdomen of a crab. It is a yellowish substance.

With the continuous improvement of living standards, people's requirements for food are getting higher and higher, so what kind of creature is the crab slave, do you know let's talk about it.

The crab slave is not a crab, but a barnacle that parasitizes the crab. The barnacles we often see are usually parasitic on uneven reefs or the bottom of boat holds, but female crab slave larvae will walk on the crab's body, looking for joints. When found, they molt and inject molluscs into the crab.

Crab slaves belong to the family Crab Slave of the order Cranopod, they are oviparous organisms, and the fertilized crab slave eggs develop into larvae on their own in seawater, and the crab slaves of the larvae are very small and drift with the tide until they meet the crab. However, not all crab slaves live as parasitics, because parasitism is only exclusive to female crab slaves, and female crab slaves only choose male crabs to parasitize.

The crab slave parasitizes the crab's body and absorbs nutrients, the crab is still alive and can continue to eat, but most of the nutrients are taken by them, and there is still a little left for the crab to continue life. But after a long period of development, once it is fertilized by the parasitic crab, it will hollow out the inside of the crab little by little, replace it, and then give birth to the next generation inside. Crab larvae will divide into multiple branch-like tubes to slowly occupy the crab's body, and the main function of these tubes is to absorb nutrients from the crab's body for its development.

In this process, the female crab slave will affect the hormone secretion of the male crab, causing the male crab's abdomen to be stretched and flattened, so that the male crab looks like a female crab.

As crab slaves develop, they will have a hard shell on the outside of their body, which can help them resist the attacks of natural predators, but at this time, the resistance is weak, and it is not easy to forage for food. When they first enter the crab's body, they are still relatively weak, and the crab does not feel their presence at all. However, they will protrude root-like branch protrusions inside the crab's body, and these protrusions can connect various parts of the crab's body, and the nutrients in the crab's body will be taken over and owned by themselves.

This creature causes the crab to become a "zombie" and will not shed its shell and will not continue to grow. Eventually, the size of the crab becomes smaller, and even the crab dies, the crab meat stinks, and the body is hollowed out. For crab farmers, this kind of thing is a nightmare.

The crab slave is a parasitic barnacle that has a thin shell (larval state) on its body before parasitism, and when parasitism is complete, its shell fades away and becomes a soft sac. The development of the crab slave from larvae to adults is completed in the crab's body, and when it is fully developed, its fully developed sac will be located in the crab's abdomen. When the offspring of the crab slave matures, the crab slave will control the crab to stand on a high rock, and then use its belly to expel its offspring from the water, and constantly use its abdomen to stir the surrounding water current, so that its offspring will flow farther and continue to repeat the life of the crab slave.

If the female crab slave parasitizes the male crab, the crab slave will affect the hormonal balance of the crab, which means that the male crab will develop the characteristics of the female crab, making them look like the female crab.

A crab slave is a creature that lives in the sea, usually feeding on small grass or shrimp.

It's a scary creature, a bacterium, they burrow into the crab's body to control the crab, and then the crab turns into a thoughtless animal.

This creature is generally parasitic on the body of the crab and is a parasite, and the bacteria of this parasite are also very powerful, which is very bad for the human body.

It is possible for crab slaves to infect humans. Crab slave is a parasite that parasitizes in crabs, crabs with crab slaves are not edible, crab slaves parasitize in the abdomen of crabs, crabs infected with crab slaves, grow slowly and the gonads are not developed, when crab slaves are seriously parasitic, crab meat will become smelly, commonly known as "bed bug crabs".

What to look out for when eating crabs.

Do not overconsume crabs in a short period of time, because the crab roe contains more cholesterol, and excessive intake will cause bad effects on the body.

Do not eat crabs raw, as undercooked crabs can leave bacteria and eggs behind, which may cause them to parasitize the human body if eaten.

Do not eat crabs that have been dead for too long, once the crab dies, the bacteria in the body will multiply, and even if it is cooked and eaten, it can cause food poisoning.

Humans as mammals are much more evolved than arthropods, and the human immune system is actually very strong and can solve many parasite problems. In addition, in terms of body size, there is no parasite that can ensure that an individual receives enough nutrients to cover the entire human body, so as to achieve the parasitic effect of the genus Crab. Without a brain that rivals the enemy, parasites are simply not strong enough to control the specific behavior of humans.

The dangers of crab slaves

For crab farmers, crab slave is one of the common parasites that harm crabs, in our country, crab slave disease is also known as bed bug crab disease, although crabs will not die immediately after being parasitized by crab slaves, but crabs develop impaired and no longer molt. When the parasitism is severe, there is very little crab meat in the crab at this time, and most of them are crab slaves, so they cannot be eaten.

In China, July to October is the peak period of the disease, and saltwater ponds with high salt content are more common, causing serious losses to local crab farmers.

However, in the years of dealing with crabs, crab farmers have also explored some ways to deal with crab slaves, that is, before breeding crabs, completely remove the pond and use certain insecticides to eliminate the crab slave larvae in the pond.

In addition, some crab farmers will stock a certain amount of carp in the crab pond, and the carp will devour the larvae of the crab slaves to control the number of crab slaves. Of course, if the crab pond is already sick, then the crab farmers will also immediately change the pool water and transfer the infected crabs to fresh water, because the crab slaves are not strong in adapting to fresh water, at this time they will die due to environmental discomfort. In addition, some crab farmers will also use certain drugs ** crabs.

In fact, at present, there is almost no crab slave disease in the crabs we eat, because crab slaves will seriously affect the yield of crabs, so crab farmers will test the water body, water temperature and crab seedlings before breeding, and strictly control them.

In addition, once there is a crab slave parasite, the crab buyer will avoid the purchase, and the conscientious crab farmer will not **, but deal with it pollution-free.

All in all, in general, in the market, we can't buy crabs with crab slaves, unless it is some unregulated market.

The "crab slave" is a barnacle creature that parasitizes the body of crabsAlthough crab slaves are barnacles, their appearance is very different from other grayish-white shelled barnacles clustered on the rocks by the sea.

Female crab slave larvae walk on crabs in search of joints. They then dehull and inject the molluscs into the crab. They grow up in the crab, forming sacs called the outer ones at the bottom of the crab.

Habitat. Staphylococci live in the marine environment. In their larval stage, they are planktonic, but when they reach adulthood, they live on crabs as ectoparasites.

Their main host is the green crab, which is native to the Eastern Atlantic. Although these crabs have spread to other waters, it is not believed that sacculina barnacles have come with them to these new places.
