The snail can tolerate a broad range of soil pH and calcium conditions, although calcium is critical for snail shell development. [7] Relative humidity, such as the amount of rain, is an important factor for snail growth. In fact, the snail's shell growth pattern will reflect rain fall patterns, much like the growth rings of a tree. [26]

The background colour of the shell ranges from dark brown, through pink to yellow or even approaching white. This variation is continuous, but there are peaks in the distribution corresponding to brown, pink and yellow morphs. [13]
