Why do snails often come out on rainy days?

Snails often come out in rainy days because they like to live in dark, humid, humus-rich and loose soil. And because snails breathe through "breathing holes", they are afraid of floods. When it rains, snails will crawl out of their nests to breathe. In addition, leaves soaked in rain will stimulate the appetite of snails, so they are often seen after rain.

Snails are the most common mollusks on land, which are distributed almost all over the world. Different kinds of snails have different body sizes. For example, African snails can be as long as 30 cm, while northern wild species are generally less than 1 cm. Snails generally feed on leaves and buds of plants, but do not eat grass plants, onions, garlic, ginger, peppers, leeks and other pungent vegetables and plants. It is very afraid of direct sunlight. During the day, it will live in a dark shelter to avoid the sun, and then come out for food at night. Snails living in cold regions hibernate, while species living in tropical regions hibernate in dry seasons. The mucus secreted during hibernation forms a dry film to seal the mouth of the shell, and then hides the whole body in the shell, and will come out to move when the temperature and humidity are suitable.
