文石壳
With the help of hydration water and organic matrix, the transition temperature of the aragonite in the shell is lower than the natural aragonite.───贝壳中的文石相在结合水和有机质的“调和”作用下，其相转变温度与天然文石相比下降了很多。
Each polyp lives inside a shell of aragonite, a type of calcium carbonate which is the hard shell we recognise as coral.───每一个珊瑚虫都寄生在一个文石壳内。文石是一种碳酸钙，也就是我们所说的珊瑚硬壳。
