Why are crayfish not insects? Are crayfish not shrimps, but insects?

Crayfish, which belong to the group of crustaceans. Crustaceans have 5 pairs of legs, 4 of which are used for crawling and swimming, and one pair of chelicerae for deterioration and predation.

Crayfish have a harder carapace on the body surface, belong to crustaceans, live in water, breathe with gills, and therefore, are crustaceans.

The most striking feature of insects: the body is divided into three parts: head, thorax, and abdomen, with 3 pairs of feet and 2 pairs of wings, and they are good at jumping and flying. There are many kinds of insect mouthparts, such as: locusts' chewing mouthparts, bees' chewing mouthparts, and so on.

Hello, crayfish (crustaceae crayfish aquaponics).

Crayfish are omnivores, and in terms of eating habits, crayfish prefer to eat mud at the bottom of the river, and like to eat small fish or other aquatic organisms that have died.

The astaxanthin content of the body is positively correlated with its ability to resist the external harsh environment, which means that the higher the astaxanthin content of the body, the stronger its ability to resist the external harsh environment.

From the perspective of biological classification, crayfish and insects both belong to the phylum Arthropods, but further down, crayfish are crustaceans, and insects are insects. Just like spiders are not insects, crayfish are not insects.

Why crayfish are not insects, crayfish are the same as fish. He is the same species as the fish.

Crayfish are shrimp species.

Crayfish belong to the phylum Arthropods, Crustacean subphylum, molluscs, decapods, and crayfish. The scientific name is crayfish.

Decapod is an order of the phylum Arthropods, the molluscs, and the largest order of the Crustacea subphylum, with a total of about 9,000 species. The body is divided into cephalothorax and abdomen. There are eight pairs of thoracic limbs, the first three pairs form the jaw feet, and the last five pairs become the foot feet. Including various shrimps, hermit crabs, crabs.

It can be seen that crayfish is an out-and-out shrimp.

Crayfish are freshwater shrimp species native to North America. Omnivorous, fast-growing, and adaptable, it has been widely introduced around the world. Crayfish.

Crayfish are crustacean, decapod, crayfish aquatic animals, not insects. Crayfish are also known as crayfish, crayfish, and freshwater crayfish.

Crayfish people belong to the shrimp category, and eating more is good for the body. Calcium supplementation and nutrition, so eating more is the same as basking in the sun.

Hope it helps you ...

Shrimp crayfish are shrimps. Crayfish is a common freshwater shrimp in life, crayfish is also known as crayfish, red crayfish and freshwater crayfish, crayfish are rich in protein, and the meat is soft and easy to digest. In addition, crayfish are rich in trace elements such as magnesium, zinc, iodine, and selenium, and have good nutritional value.

I think crayfish also belong to the shrimp category, not to be insects.

Lobster (scientific name: Palinhoceae) is a collective name for the family Arthropodae, cladoperates, and phyllaceae. It is also known as prawns, dragon head shrimp, shrimp, and sea shrimp.

It has a thick head and thorax, a hard shell, bright colors, a short abdomen, a body length of generally between 20 and 40 centimeters, and a weight of about kilograms. Some don't have pliers, and the next day their abdominal limbs can become pliers. The heaviest can reach more than 5 pounds and is called a lobster goby.

The body is stout and cylindrical, the back and abdomen are slightly flat, the head and thorax are well developed, stout and spiny, the anterior margin ** has a pair of powerful supraocular spines, and the gill chamber is closed. Mainly found in tropical waters, it is a rare seafood.

Crayfish have parasites. But if you want to eat crayfish, you can buy it yourself, wash it, and boil it in water, and you need 80% or 90% boiled sheep to cook it to kill the parasites. Let's cook the crayfish ourselves, and if the parasites in it can't kill them, don't fry them by frying.

Whether the crayfish is clean or not, don't buy it outside. No one knew if it was cooked thoroughly, so friends who wanted to eat crayfish bought it and cooked it themselves. It's safe and hygienic.

Crayfish is a type of freshwater crayfish that belongs to the subfamily Crayfish of the Arthropod phylum Crustaceae. It also has its own scientific name, Crayfish. The homeland of crayfish is not in China, nor in Japan, but far from North America.

Its primary habitat is the Gulf Coast, especially near the Mississippi River estuary.

The crayfish is not a worm but a crustacean that belongs to the suborder Reptile Crabs. There is a historical reason to say that it is a bug. In ancient times, these little things were called bugs.

From the side of the word "shrimp", it can be seen that snakes, scorpions, crabs, spiders, and earthworms are also considered insects. So, in ancient times, you were right to say that it was a bug, but now the term "bug" usually refers to insects in arthropods. Crayfish belong to the class Crustacea of the phylum Arthropods and are parallel to insects.

In fact, to be honest, it really doesn't make sense to distinguish whether a crayfish is an insect or not. Think about the difference between shrimp and insects. It's just that the meat is softer and easier to eat.

Crayfish, whose real name is crayfish, is a type of freshwater shrimp. It is related to lobsters, and taxonomically they are all "decapods". Lobsters belong to the macrophyllous moss family, protocrayfish or crayfish, while the crayfish we eat belong to the cricket family (so in some areas of northern China, it is directly called "mole cricket").

Crayfish are native to the southeastern United States, so they are also known as American crayfish. It is located near the Gulf of Mexico, especially in the mouth of the Mississippi River, so it is also called Louisiana crayfish. It is the most consumed freshwater lobster species, accounting for 70-80% of the total freshwater lobster production annually.

Personally, I think there is still a scientific basis for this, after all, lobster is very rich in protein, which is similar to that of bugs.

There is certainly no scientific basis. It's just speculation.

The real name of the crayfish is "Crayfish", and the scientific name is Procambarus clarkii, which is a kind of freshwater shrimp that is like a fake. It is related to lobsters, taxonomically they are all "decapods", lobsters are lobsters, crayfish or crayfishes, and the crayfish we eat are crickets (so in some areas of northern China it is directly called "crickets").

In fact, there are four kinds of authentic crayfish in China, which are Northeast crayfish, Nanjing crayfish, Shi's crayfish and North Korean crayfish. In addition, there are two kinds of "foreign monks", the crayfish native to the United States and the red crayfish native to Oceania, but the crayfish is more skilled and blooms everywhere in China, becoming the most famous crayfish. The delicious crayfish is actually an invasive species, this shrimp has a ferocious temperament, reproduces quickly, and is extremely adaptable to the environment, which also poses a threat to the "aborigines".

Crayfish is an omnivore, the main food is the organic matter at the bottom of the water, aquatic plants, algae, aquatic insects, organic detritus are its food, of course, it also eats small fish, small shrimp, shellfish and other living creatures, and even cannibalism when it is not full. Because it eats heterogeneous, it has a strong vitality and can survive in polluted water. But the crayfish in restaurants are basically farmed, such as the one in Guijie in Beijing, which basically comes from the farm in Xuyi.

In the breeding environment, animal and plant feeds should be fed according to the needs of growth, such as wheat bran, soybean cake, aquatic insect larvae, etc. Crayfish tolerate polluted water, but they don't like that. Some scholars have done experiments and found that crayfish are more inclined to choose fresh food and prefer clean water, so living in sewage is purely helpless.

Moreover, there is a limit to the tolerance of crayfish to the environment. If the water quality is poor, crayfish not only have difficulty reproducing, but also grow poorly and shed their shells slowly. Under breeding conditions, the density of crayfish is relatively large, if the water is very dirty, their vitality will be significantly reduced, as soon as the weather is hot, the shrimp will die in large numbers, and can not withstand long-distance transportation, so farmers will also pay attention to water quality maintenance.

Is a crayfish a worm and not a shrimp? Is it truth or rumor?
