  text: The growth of snail shells can be described by simple mathematical rules.
    Variation in a few parameters can explain much of the diversity of shell shapes
    seen in nature. However, empirical studies of gastropod shell shape variation
    typically use geometric morphometric approaches, which do not capture this growth
    pattern. We have developed a way to infer a set of developmentally descriptive
    shape parameters based on three-dimensional logarithmic helicospiral growth and
    using landmarks from two-dimensional shell images as input. We demonstrate the
    utility of this approach, and compare it to the geometric morphometric approach,
    using a large set of Littorina saxatilis shells in which locally adapted populations
    differ in shape. Our method can be modified easily to make it applicable to a
    wide range of shell forms, which would allow for investigations of the similarities
    and differences between and within many different species of gastropods.
