The structure of the gastropod shell is able to withstand mechanical damage thus, we hypothesize that there is a correlation between wave frequency and morphological features. we measured the wave frequency by establishing point upon which waves with white foam crashed for 5 minutes. Using the same point as center of 5 meter line transect, we collected gastropod specimen on rocks which the transect touched. We then repeated the procedure at each site but at a different location within that site and categorized the gastropods into morphotypes based on shell shape and texture. We found 8 morphotypes and used the general linear model (GLM) to discover that wave frequency (WF) significantly influences total gastropod abundance (p= 0.0013). Additional GLM tests revealed that WF also significantly influences shape and texture (See following hyperlinks).File:Shape.pdf, File:Texture.pdf In terms of shape, the influence of WF on shell shapes is seen by the hierarchy of the GLM generated estimates:conical< side spiral < upward spiral < unclear spiral. In terms of texture, the hierarchy is rough < smooth. According to the Wikipedia article titled 'Gastropod shell,' the morphotype we have deemed as unclear spiral tends to have a larger aperture (opening of the shell), thus it can withstand more turbulent waters and is likely to found in the intertidal zone than the other morphotypes.Thus, the article supports our findings on the relationship between gastropod shell morphology and the wave frequency.
