From: Pteropods make thinner shells in the upwelling region of the California Current Ecosystem
Variation in shell thickness measured by micro-CT scans of two Limacina helicina specimens. (a) A thick shell sampled offshore (station 101). (b) A thin shell sampled onshore (station 99). Coloring indicates shell thickness, with brighter colors for thicker areas. (c,d) Frequency distribution of shell thickness of the two specimens. These frequency distributions were used to calculate average thickness per shell.
