The range and strength of misorientations between chamber wall crystals for A. lessonii and A. lobifera. The shells were secreted first in Cd²⁺- and Pb²⁺-uncontaminated water ((A), (D)). The last chambers were formed in Pb²⁺- and Cd²⁺-contaminated water (Fig. 11B, C, E, F). The only difference that we find is in the 60° misorientation. For the other misorientations, there is no marked difference in range and strength between them. However, the difference in 60° misorientation is striking. For a closer look at the 60° misorientation peak, see Fig. 12.
