However, the appearance of the snails is too similar to that of the field snails. If you eat the snails by mistake, the consequences will be unimaginable.
There is a parasite, nematode, in the snail. When it enters the human body, it will destroy the nerve tissue and make people become dementia or even die. What's the difference between a snail and a snail? Hurry up and have a look with Xiaobian.
Fushouluo and Tianluo -- appearance difference
1. Spiral shrinkage diameter
Both the diameter and the angle of the Shell Helix contracted rapidly from the outside to the inside, but the contraction of the snail was relatively slow.
2. Antenna length
The antennae of the snails are thin and long, while those of the snails are short and thick. The mouth of the snails is slightly divided and has two 'beard' like organs (equal to 2 pairs of antennae), while the snails are a cylinder (1 pair of antennae).
3. Tail length
The size of the snails is different from that of the field snails. The top of the snails is bigger and the bottom is smaller, and the tail is shorter. The snail is smaller from top to bottom and has a long tail.
4. Cap shape
The cover of the snail is flat, and the shape of the cover of the snail is round.
5. Color difference
The color of the meat is light, mostly yellow and white, while the meat of the snail is mostly green and brown.

The eggs of the snail are transparent and jelly like, which are usually submerged in the water; the eggs of the longevity snail are pink, which are generally adhered to the plants on the water surface, and the eggs of the small snail become white and broken after breaking the shell.
Fushouluo and Tianluo -- touch difference
The shell of the longevity snail is very fragile. It can be easily pinched and exploded by hand, and it will be broken properly on the ground. However, the texture of the shell of the field snail is hard, so it is not only difficult to pinch and explode by hand, but also easier to smash on the ground.
Fushouluo and Tianluo -- species difference
The snail is not easy to cross, and there is no gene of beautiful offspring. Its appearance is generally 'earthy'. But this species is complex and easy to mutate. Now we have cultivated golden and safflower varieties, which are often called golden and mysterious snails.
Different growth characteristics of the snails
1. Growth speed and life
The snail grows slowly, some of which remain immortal for 4 years. The snails grow rapidly, but even if they are carefully raised, 2 years is the limit.
2. Size
The snail usually grows to the size of grape, and the walnut size is basically the limit, while the longevity snail can grow to the size of grape in one month, and can grow to the size of walnut or even egg in one summer.
3. Activity
The snails are lively and active, while the snails are quiet and slow; the snails eat a large amount of food, and the snails chew and swallow slowly. In the market, the pet aquarium usually sells the conch,
