When two snails meet, they touch each other with their antennae, and then their heads are opposite to each other and their bodies are joined together, with the genital cavities of each other in position. After a few moments of this temporary pause, the reproductive parts are suddenly reversed, and each inserts its love vector (penis) into the other's genital hole. Generally speaking, the snail's copulation time is very long, each copulation takes about 2-3 hours, and sometimes can reach as long as 4 hours.
After copulation, fertilized eggs are produced through the genital pore. The eggs are laid in the soil several millimeters deep underground or under rotten wood or fallen leaves. The snail's larvae develop in the egg shells and hatch out into snail-like larvae.
1. Snails are hermaphroditic, heterogamous, and both sexes lay eggs. The snail itself acts as both father and mother. The two snails cooperate with each other, both sides will love vector (penis) repeatedly stimulate each other's genital holes, after intense stabbing movement, both penises will be inserted into each other's vagina ejaculation. After 10 days of fertilization, both sides can lay eggs, and the eggs can hatch out small snails after 8 days.
2. Mating time is long, egg-laying is slow and the degree of difficulty is high. The mating time of snails in heat is as long as 2 to 3 hours each time, and some are as long as 6 hours or more. Snails can lay 2 eggs per minute, and each egg-laying time lasts 1 to 2 hours, with some lasting more than 3 hours. Snails in the egg-laying process, often due to poor feeding and nutritional deficiencies, defecation and difficult to produce and die. Some of the deaths due to difficult labor accounted for about 30% of the total number of species of snails.
3. High reproduction rate. Each snail can lay eggs 6 to 7 times a year, each time an average of 200 eggs. Breeding snails weighing 35 grams can produce 120 eggs each time, snails weighing 40 to 50 grams can produce 150 to 180 eggs each time; snails weighing 60 to 100 grams can produce 300 to 400 eggs each time.
4. The reproduction of snails is not limited by age. Under the same suitable conditions for reproduction, the larger the snail, the more eggs it produces.
5. Short life span. The life span of snails is generally 5 to 6 years. Under uncomfortable living conditions, it will accelerate the death of snails and shorten their lifespan.
6. Three slow, two fast, one difficult and one more. Three slow is slow action, slow mating and slow spawning; two fast is fast growth and fast shell shrinkage; one difficult and one more is difficult to spawn and spawn more.
