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.
