In the present paper, juvenile and adult shells of the green ormer Haliotis tuberculata
('Oreille de Saint-Pierre') were perforated in a zone close to the shell edge and the shell
repair process was followed at two levels:(1) by observing the histology of the calcifying
mantle in the repair zone and (2) by analyzing with SEM the microstructure of the shell repair
zone. Histological data clearly show the presence of calcium carbonate granules into the
connective tissues, but not in the epithelial cells. This suggests that calcium carbonate …
