Fig. 12

Difference in frequency of 60° misorientation for A. lessonii ((A) to (C)) and A. lobifera ((D) to (F)) chamber walls secreted in uncontaminated ((A), (D)) and contaminated ((B), (C), (E), (F)) environments. We observe: (i) a metabolic effect, with a difference in the height of the 60° misorientation peak for the shells of the two investigated species and (ii) a “polluting agent” effect, with a difference for the height of the 60° misorientation peak, thus twin formation, for Cd2+ and Pb2+.
