1, the secret of snail movement: snail crawling by the abdomen and feet, the speed of each crawl is unchanged, that is, the snail is moving at a uniform speed. The crawling speed of the snail is directly related to the abdominal foot movement, we see the snail gastropod muscle contraction from the back to the front, and then the gastropod is released, the snail can be fully extended, the body slides forward, and the abdominal foot muscle is a wave contraction movement.
2, the secret of snail smell: snails have a sense of smell, and do not like things with irritating odors.
3, the secret of snail breathing: pour half a cup of water, put five or six snails into the water, each snail fell into the water, immediately put their heads out, all climb towards the top of the cup. This shows that snails need to breathe air.
4, snails are afraid of salt water: snails are mollusks, body meat water accounts for a large proportion, when you see the liquid, it is not water, but because of the oozing of water, the original volume becomes smaller. In fact, the snail does not melt, but the body is rapidly dehydrated, but the internal organs and major organs are there.

Life Habits:
Snails like to live in a dark, humid, loose and humus-rich environment, day and night, the most afraid of direct sunlight, sensitive to environmental reactions, the most suitable for the environment: temperature 16 ~ 30 ° C (23 ~ 30 ° C, the fastest growth and development); air humidity 60% ~ 90%; feeding soil humidity of about 40%;
The pH is 5 to 7. When the temperature is below 15 ° C, above 33 ° C, sleep, below 5 ° C or above 40 ° C, it may freeze to death or heat death. But all kinds of snails are different.
Snails like to burrow into loose humus to roost, lay eggs, regulate the humidity in the body and absorb some nutrients for up to 12 hours. Omnivorous and partial eaters coexist. Prefers humidity and fears flooding. On wet nights, and put in wet feedings, snails have an active appetite. But flooding can suffocate snails.
