1. How long does it take for snail eggs to hatch?

Snails refer to mollusks of the family Snailidae, belonging to the class Gastropoda, subclass Prosobranchia, family Snailidae. Common freshwater snails include the Chinese round snail, which is distributed in most parts of China, and is widely distributed in freshwater lakes, reservoirs, rice fields, ponds and ditches across my country. Because of its tender and delicious meat, rich nutrition, and therapeutic effects such as clearing heat and quenching thirst, and improving eyesight, it has become one of the favorite aquatic products, especially for southerners who regard it as a delicacy at banquets.

Snails have high requirements for water quality and low yield. They can be caught in summer and autumn. Snails are dioecious, and the method of distinguishing male and female snails is mainly based on the shape of their right antennae. The right antennae of male snails bend to the right (the bent part is the male reproductive organ). In addition, female snails are large and round in closed position, while male snails are small and long.

Snails are cold-resistant but afraid of heat. The most suitable growth temperature is 25℃. They will stop eating when the water temperature is below 15℃ or above 30℃. They will burrow into the mud when the water temperature is below 10℃, and will be scalded to death when the water temperature exceeds 40℃. Snails have a mixed diet and like to move and eat at night. They can reproduce naturally. The lifespan of snails is generally four to five years for females and two to three years for males. The growth of young snails is fastest in the first three to four months, and then gradually slows down. After two years, they basically stop growing.

The snail is an ovoviviparous animal with a unique reproductive method. The embryonic development and the development of the snail's young are completed in the mother's body. The mature eggs meet the sperm at the top of the oviduct and are fertilized. The fertilized eggs undergo embryonic development in the mother's uterus, and the mother directly gives birth to the young snails. It takes about a year for the fertilized eggs to be produced in the mother's body. The snails lay eggs in batches and begin to reproduce from March to April every year. While producing young snails, the female and male parent snails mate and fertilize, and at the same time, they breed the young snails to be produced the next year in the mother's body. Mating behavior usually takes place during the day, and the mating time can be as long as 12 hours. Most of the young snails are produced at night. A female snail produces about 100 to 150 young snails throughout the year.

The snail follicles cannot hatch anything when swimming in the water. They should be placed in a waterless place and the air around the hatching should be kept at a high humidity. You can use a wet toilet paper to pad and place them in a box for hatching. Snails refer to molluscs of the Snail family, belonging to the Mollusca, Gastropoda, Prosobranchia, Snail family. Snails are distributed in most parts of China. Snails have high requirements for water quality and low yields. They can be caught in summer and autumn. Chinese round snails are common in freshwater. Snails are dioecious. The method of distinguishing male and female snails is mainly based on the shape of their right antennae. The right antennae of male snails bend inward to the right (the bent part is the male reproductive organ). In addition, female snails are large and round, while male snails are small and long. Snails are ovoviviparous animals with a unique reproductive method. The embryonic development of snails and the development of young snails are completed in the mother's body. It takes about one year for the fertilized egg to produce young snails in the mother's body. The snails lay eggs in batches and start to reproduce in March and April every year. While producing baby snails, the female and male parent snails mate and fertilize, while the mother snails breed the baby snails to be produced the next year. A female snail can produce about 100 to 150 baby snails in a year.

The eggs of snails can usually hatch in about 8-45 days, which is also closely related to the water temperature. Snails can grow in low and medium-high temperatures and have a strong ability to adapt to the survival temperature. The water temperature can directly affect the growth of snail eggs. There are many varieties of snails, and different varieties have different hatching times.

The embryonic development and larval development of river snails are all completed in the mother's body. It takes about a year for the fertilized eggs to be produced. River snails lay eggs in batches, starting to reproduce from March to April every year. When the larval snails are produced, the female and male parent snails mate and fertilize, and at the same time, the larval snails to be produced the next year are nurtured in the mother's body. A female snail produces about 100 to 150 larval snails throughout the year.

2. Why do snails give birth to cubs directly?

The reason why field snails give birth to baby snails directly is that they are ovoviviparous animals with a unique way of reproduction. The embryonic development and baby snail development of field snails are completed in the mother's body.

It takes about a year for the snails to grow from fertilized eggs to young snails. The snails lay eggs in batches and begin to reproduce in March and April every year. While the young snails are being produced, the female and male parent snails mate and fertilize, while the young snails to be produced the next year are being nurtured in the mother's body.

Ovoviviparity (also known as pseudoviviparity) refers to a form of reproduction in which the eggs of animals are fertilized and develop in vivo. Although the fertilized egg develops into a new individual in the mother's body, the embryo is not closely related to the mother in terms of structure and physiological function. The nutrients required for embryonic development mainly rely on the absorption of the egg's own yolk, and the embryo can also exchange some substances with the mother's oviduct. This is a reproductive method formed by the long-term adaptation of animals to adverse environments. In fact, the mother mainly protects the embryo and incubates the offspring.

It means they are viviparous. To put it more clearly, it is the same as animals, like snails, there is no distinction between male and female, as long as there are two of them, they can reproduce. Those with internal fertilization are all viviparous, and those with external fertilization are oviparous (for example, some fish give birth to fish eggs, which are fertilized outside the body). Do you understand?

In fact, snails are oviparous, but the entire process from eggs to snails hatching takes place inside the mother's body, so it gives people the illusion that the snails are born directly.

3. In which month do snail eggs hatch?

Tiankongchang snails lay eggs in batches and begin to reproduce from March to April every year. While producing young snails, the female and male parent snails mate and fertilize, and at the same time, the mother snails breed the young snails to be produced next year. A female snail can produce about 100 to 150 young snails in a year.

Snail eggs cannot hatch out of water, so they should be placed in a waterless place, and the air around the hatching area should be kept at a high humidity. You can use a piece of wet toilet paper to pad the eggs and hatch them in a box.

Snails refer to mollusks of the family Snailidae, belonging to the class Gastropoda, subclass Prosobranchia, family Snailidae. Snails are found in most areas of China. Snails have high requirements for water quality and low yields. They can be caught in summer and autumn. Common freshwater species include Chinese round snails. Snails are dioecious. The method of distinguishing male and female snails is mainly based on the shape of their right antennae.

The right antenna of the male snail is bent to the right (the bent part is the male reproductive organ). In addition, the female snail is large and round, while the male snail is small and long. The snail is an ovoviviparous animal with a unique reproductive method. The embryonic development and the development of the snail are completed in the mother's body. From the fertilized egg to the birth of the snail, it takes about a year to grow in the mother's body.

The snails lay eggs in batches and begin to reproduce from March to April every year. While producing the young snails, the female and male parent snails mate and fertilize, while the mother snails are nurturing the young snails to be produced the next year. A female snail produces about 100 to 150 young snails a year. In most parts of my country, the eggs are usually hatched in May. Some are particularly early in March, and some are not until July.

The key is temperature. If the temperature is right, the eggs can be hatched.
