【 摘 要 】

Seashells are comprised largely of a brittle ceramic material (calcite, the stuff of chalk) in the form of microscopic slates. Shells, such as the abalones, reinforced with a kind of protein mortar in efforts to evaluate on how seashells repair themselves. We have identified the protein and mechanism on how the protein mortar stretches itself into ligaments that bridge the gap, with the help of scanning electron microscope (SEM).
