表型可塑性提供生物快速且有效地反應環境變化的能力。二氧化碳排放造成的海洋酸化對鈣化生物的生存有很大威脅，多樣的貝類殼紋即是表型可塑性的表現，這與他們適應環境的能力有關，本研究要瞭解貝類外表殼紋和截面上生長紋路的關聯。貝殼的碳酸鈣儲存是動態的，溶解與再結晶都會發生，規律性的殼紋與再結晶是產生貝殼內毛細管網絡的關鍵，毛細管網絡能協助 pH 值的調節。不過，不具規律性殼紋的貝類對暴風雨的天氣顯現較高的忍受度。探討不同表型的適應能力有助於對抗海洋酸化的努力。

Phenotypic plasticity which results in variation of observable traits provides adaptive potential for organisms to changing environment.Carbon dioxide emission and industrial pollution have raised concerns about how calcifying organisms respond to acidifying environment. This investigation is to study appearance-related physiology of shellfish with samples collected from a fishery. Biocalcification is involved in the pH balance mechanism which is greatly influenced by acidifying environment. A delicate capillary network inside the calcified shell facilitates the dissolution and storage of calcium carbonate. Coloration and pigmentation pattern on the shell affect the development of the capillary network. Shellfish with lighter shell colors normally exhibit higher tolerance to prolonged adversity. Environmental conditions can affect the growth rates of different phenotypes.
