Problem statement: There are many species of Helix snails, each with its own unique exoskeleton shape, or shell shape. Principal analysis of measurement data from snail shells occupied by Helix points out the importance of the description and quantification of the snail shells. The present paper is aimed to compare some of the formulas in the literature used to determine the volume of snail shape.
Hypothesis: The methods and formulae which exist do not reflect the real shell volume (at least not precisely enough) but rather use the external measurement and on that basis they draw conclusions for the biomass and the development stage.
Organisms: 142 species of the Turkish snail (Helix lucorum).
Approach: The purpose of this study is to improve and to offer a much better and accurate formula for calculations of the shell volume.
Conclusion: Our results support the usage of the formulae, and confirm some of these formulas while disproving others. As a result we developed a formula which takes into consideration the varying shape and thickness of the shell and reflects the real shell volume in most of the cases.
