The baby crab born from the female crab seems to be dead?

Where is your home? If there is water along the coast or nearby, and there are crabs after the rain, it is not surprising that there are several frogs in my house after the rain... In the downtown area of Beijing.

A while before the frog infestation, I fished a lot of tadpoles from the river, and then I forgot about it in the yard, and after the rain, there was no one left in the basin, so it should have been washed into the sewer. It is estimated that the tadpoles turned frogs. It's puzzling where tadpoles turn into frogs.

It had been almost a month since I was washed into the house and found the frog. Although it is the rainy season, there is not much rain in Beijing. =。

This question has been bothering me for a long time) In addition, the super little crab you mentioned should be a real baby, and the crab is similar to a kangaroo, which hatches offspring in the pelvic fin. When the fertilized egg matures, it becomes a larvae and leaves the mother.

How do you divide male and female crabs? Tips to help you identify (**).

Brief introduction: How to divide male and female crabs? The Golden Autumn Festival is a good time to eat crabs. There are many female crabs, so many people want to know how to divide male and female crabs.

The above saying is that the mother crab is a round umbilicus, the eggs are full in September of the lunar calendar, and the crab roe is fragrant and delicate; The male is a sharp umbilicus, and the yellow fat paste is white in October, and the taste is plump and round.

There are several ways to identify a dead crab:

1. The carapace of the back of the live crab is blue-gray, shiny, the abdomen is white, the golden claws are thickly covered with yellow hair, the color is bright, the umbilicus is rounded, and the outward convex, while the back of the dead crab is dark red after cooking, and the abdomen is gray-white, which can be identified at a glance.

Second, the shell of the dead crab is relatively soft, the muscles of the whole body are relaxed, and the limbs and chelae naturally droop when they are picked up, and there is no muscle tension.

3. There are always some bubbles in the mouth of the live crab, and a slight bubble bursting sound can be heard, and the dead crab basically does not move.

Eyes don't move: When a live hairy crab is touched, its eyes move automatically, while the eyes of a dead crab don't move on their own. Crab claws do not retract:

Pull the legs of the hairy crab apart with your hands, and the claws will not retract when pulled, indicating that the crab is dead. No bubbles: Put crabs in half a basin of water, and if they don't spit out bubbles for a long time, they are dead.

The mother crab gives birth to a baby crab and does not die. Each time, the female crab lays a large number of eggs, which can reach more than one million. After these eggs hatch in the belly of the mother crab, the larvae can break away from the mother and float around with the coastal currents.

After several shells, they grow into big-eyed larvae, and the big-eyed larvae grow into juvenile crabs after several shells, and the appearance of juvenile crabs is almost the same as that of adult crabs, and then after several shells, they become crabs. Most marine crabs are released into the ocean without hatching after their eggs have matured.

Because the little crabs are made into crab sauce.

It's best not to eat it, because it's too long to die, a few months ago I bought the Yangcheng Lake hairy crab in Su Crab Pavilion, and it was good when I brought it, but I raised a few of them, and I was afraid that it would be wasted, so I said that I cooked it and ate it, and then called their customer service ** and asked me not to eat it.

1.Dead crabs are not recommended to eat. Crabs love to eat rotten food, and pathogenic bacteria and toxic substances accumulate in their bodies. Dead crabs can quickly grow a large number of bacteria in their bodies, so they should not be eaten, especially in hot weather.

2.In terms of taste, the crab loses its original umami after it dies. There is also a histidine substance in the crab's body, histidine is easy to decompose, histamine and histamine-like substances can be produced under the action of decarboxylase, and the midgut gland will soon fall apart after the crab dies, and the histidine and digestive enzymes in it will decompose the crab meat.

Therefore, the taste of dead crabs is strange and the taste is greatly reduced.

3.The crab itself is non-toxic, but after the crab dies, after the crab's shell is broken, the protein in the crab's body will breed bacteria, and the infected bacteria in its body will multiply, and the bacteria may produce toxins. Dead crabs are likely to be poisonous.

4.The body of the crab is easy to carry heavy metals, after the crab dies, the midgut gland will quickly fall apart, and the digestive enzymes in it will decompose the crab meat, and the intestinal gland is relatively easy to enrich heavy metals, and the heavy metals will also come out after it rots to produce pollution.

5.If the crab has not been dead for a long time, it can still be eaten if it is refrigerated, remember, it is refrigerated and not frozen, and the sea crab is better than the river crab, because the living environment of the river crab is worse and there are more bacteria.
