What color is a snail after it dies and what color is the flesh of a snail?

The above is pure nonsense, the snail has been in the ditch river for a long time, it is generally blue-gray, and after death, the body decays and only leaves a blue-gray shell, and after a long time, the shell will also become gray-white.

Colorless and transparent The blood of animals is red because the main component of red blood cells in the blood is hemoglobin, which contains iron, and iron forms a complex with other compounds to appear red. However, not all animals' blood is red. Some lower animals, such as mussels and snails in mollusks.

The blood of prawns, giant river prawns, etc. in arthropods contains hemocyanins, and the blood is colorless and transparent, and the blood of horseshoe crab in arthropods contains the element copper, so its blood is blue. None of these animals had hemoglobin in their blood.

Snail The snail is a mollusk, a type of snail. The body is divided into three parts: the head, the feet, and the internal organs, and the head has a mouth, eyes, antennae, and other sensory organs. There is an outer shell on the outside of the body.

The foot muscles of the snail are well developed and are located on the ventral surface of the body. The diaphragm attached to the soles of the feet is called a snail, which is like a round lid, and when it encounters an accident or needs to rest, the snail shrinks its body in the shell, and contracts through the muscles of the foot to cover the shell tightly. The snail is edible, and the edible part is mainly its fleshy sufficiency.

Snail: It is the whole of the snail family Chinese round snail or its same genus. It is found in most parts of the country and is widely distributed in fresh water. Catch in summer and autumn. The sex taste is sweet, salty, and cold.

Ask the biologist! You can also go to the vegetable market yourself, thank you!

Snail. The snail meat is white, except that the front has black antennae. No matter the region, it is customary to use sauerkraut, capers, and sour chili peppers to fry snail meat.

The snail meat is gray-white, and the snail is found in large and small lakes and ponds, so it is recommended to catch one and take a look. Guangxi's snail noodles are made with snail meat and rice noodles, which are very delicious.

1. To judge whether the snail is or is dead, you can press the cover at the snail mouth, and press it to bounce up as a live snail, if it can't bounce up, it will be a dead snail.

2. The dead snail meat will turn into water, so it will be very light, soak the snail in the water, the live snail will expose its body in the water for a while, and quickly retract it when it touches it, if it floats up, it proves to be a dead snail.

3. The snail that has been dead for a period of time has a more obvious fishy smell.

1. The live snail will expose its body in the water for a while, and it will quickly retract as soon as it touches it.

2. The dead will float in the water.

3. If you put it in water, it will spit out the meat, and the one that will spit bubbles is alive, and if not, it is dead.

4. The snail that has been dead for a period of time has a more obvious fishy smell.

5. Use the tip of your little finger to gently press on the cover, the elastic is a live snail, and the other is a dead snail.

If the snail is dead or alive, it should be easier to judge the collapse and break, and under normal circumstances, if the snail is normally active, it will not open much time when it is put into the water. , what is not opened is dead.

The snail will shed its shell when it dies, and the suitable temperature for its life is 20 28, and the water temperature is lower than 10 or higher than 30, that is, it will stop feeding, burrow into the soil, and the grass will avoid the cold and heat. When the water temperature exceeds 40, the snail is scalded to death. During the dry season, it completely retracts the soft part into the shell to reduce water evaporation; During the cold winter months, it burrows into the dirt and hibernates without eating.

When the temperature rises to the point where it is suitable for its activities, it crawls with its head and feet out of its shell. When it is optimally grown at a temperature of 20 to 26 degrees, it feeds most vigorously and grows the fastest. When the water temperature rises to 30 degrees, stop eating.

It is not tolerant to high temperatures, but it is very hardy, and it burrows to overwinter during the cold season.

Snails are very fragile in the first few days of life, and they can die from many environmental factors. Here are some of the possible causes of snail death:

1.Environmental problems: Because snails are aquatic animals, if the water quality is not good or lack of oxygen and nutrients, the metabolism and respiratory functions in the snail will be affected and die.

2.Feed problems: Hatched snails need proper feed for nutrition, if the type and quality of feed is not suitable, it may lead to nutrient deficiency or poisoning and death.

3.Disease problems: Under normal circumstances, snails can be infected with various diseases such as heparin cyst worm, hookworm luteum, etc. If a snail is infected with disease and silver disease, it may trigger and exacerbate the snail's death.

In short, the growth and reproduction of snails need a healthy and suitable environment, as long as we pay attention to the breeding environment and growth status of snails, and give appropriate maintenance and management of the state banquet, and early prevention and control of the impact of the above reasons, we can reduce the risk of snail death.

Fresh snails are large, round, thin, cover complete contraction, snail shell is light cyan, no damage to the shell, no meat overflow, when selecting, gently press it with the tip of the little finger to cover it, elastic is a live snail, on the contrary, it is a dead snail.

Moreover, the snail is not large, only the small part of the upper part of the snail mouth (the head and feet of the snail) is edible snail meat, and the lower part of the five organs should be discarded when eating the snail. Notes:

1. Soak the snail in the water, and the snail that floats up is already dead.

2. After frying the snail, the small piece on the mouth of the snail is easy to fall off is fresh, if it is stuck with the snail meat and not easy to separate, it means that the snail has died before frying and is not fresh.

3. It is best to raise it with chili peppers, rather than salt, because if the amount of salt is not well mastered, the snails will become small corpses.

4. If the shell of the snail is dirty, such as moss or something, Jane He can be scrubbed with a steel wool ball.

5. In order to ensure food safety, the cooking time must be long enough. Tips: Snail meat should not be taken with traditional Chinese medicine clams and western medicine oxytetracycline; It should not be eaten with beef, mutton, broad beans, pork, clams, noodles, corn, winter melon, muskmelon, fungus and sugar; Do not drink ice water when eating snails, otherwise it will cause diarrhea.
