Snails like to come out after rain. What's going on here?

In the evening after the rain, the weather is particularly cool. When we walk on the country road, we can always find many snails moving slowly on the wet trunk. This phenomenon is rarely simple in sunny days, as if snails don't want to move in sunny days, so why do snails like to come out after rain?

In fact, the main reason is that snails like dark and humid environment. After the rain, the air humidity is relatively high and the temperature is suitable, so snails come out to move. Where are these snails when it doesn't rain? Why do we seldom see them? Snails usually stay in dark and humid places, which can avoid direct sunlight, especially like to drill into loose surface soil, which contains nutrients that snails need, which is why the color of snail shells is like soil, which can protect snails from being discovered by natural enemies. Although the shells of most snails are grayish brown, there are some snails whose shells are colored.

Of course, these snails with colored shells are far away from us. In Cuba, they are called Cuban snails, also known as Cuban candy snails and Cuban colored snails. Cuban snails are called the most beautiful snails in the world because of their high face value. Do these colorful Cuban snails also live in the soil?

Of course not. Cuban snails generally live in trees, especially coffee trees, and mainly eat fungi and mosses attached to bark and leaves. Are there colored snails in other places besides Cuba? Cuban snails are very sensitive to changes in environment, humidity, light, temperature and severity. At present, they can only live in Cuba and cannot adapt to the environment in other regions. In order to make profits, local people used to catch snails and sell these colorful snail shells to tourists as handicrafts, resulting in fewer and fewer beautiful little creatures. When colorful snails are about to become extinct, the Cuban government has taken effective protection measures and rarely made specimens.
