Nocturnal, omnivorous, mostly active in humid environments, likes to rain and haunt at night. Usually hide in a cool place, and make a layer of white film (false cover) on the shell mouth, leaving only a small hole to breathe, shrink the snail meat into the shell to prevent dehydration, wait until the environment turns better before coming out.
