When the snail is disturbed, it simply withdraws or pulls itself back into its shell. The snail also retreats into its shell and seals the entrance in dry weather to protect its body from drying up. A snail is most active at night and on cloudy days. It does not like the sunshine very much. During very cold weather or winter, it hibernates in the ground.
Snails have different shaped shells.
It can be a single shell that is rounded, spiral high and pointed or it can be flat. Some people keep snails in aquariums together with their fish. Snails do not like hot and dry conditions. They like it moist or humid and not too bright. You can collect some snails and put them into a transparent container.
