Figure of shell thickness vs shell diameter data from The impacts of past, present and future ocean chemistry on predatory planktonic snails

Figure S4. The relationship between maximum shell diameter and shell thickness of Atlanta ariejansseni. (a) The thickness of shell grown prior to the experiment shows a significant negative correlation to the maximum shell diameter, indicating that shell becomes thinner as the specimen increases in size. (b) The thickness of shell grown during the OA experiments is not related to maximum shell diameter because the normal growth was altered by varying pH and an increase in food concentration. (c) Mean thickness of shell grown prior to the experiment significantly correlates to the mean thickness of the shell grown during the experiment. (Pearson r=0.687, p=<0.001). So, the specimens that grew thicker shells before the experiments grew proportionally thicker shells during the experiments. This demonstrates that individuals also naturally vary in their ability to calcify, and these individual differences persist across the changes in environmental conditions that they experienced within our experiments.
