腔肠动物的

The coral polyp is a kind of coelenterate in the ocean, it, in order to pray on the tiny planktonic organism in the ocean as the food, can absorb calcium and carbon dioxide in the sea water in the course of growing, then secrete out the lime stone, turn into the outer cover that oneself survives.

珊瑚虫是海洋中的一种腔肠动物，它以捕食海洋里细小的浮游生物为食，在生长过程中能吸收海水中的钙和二氧化碳，然后分泌出石灰石，变为自己生存的外壳。

Any of numerous usually marine and free-swimming coelenterates that constitute the sexually reproductive forms of hydrozoans and scyphozoans.

In my experiments, I use the anemone, as my material. My major topic is how the calcium phosphates preserve the details of the cell structure by infiltrating into the cells first and following mineralize on the structure inside the cells with environmentally conditional variations.

实验中我选用了海葵，一种腔肠动物作为实验材料，研究的方向主要在於磷酸及钙如何进入到海葵的细胞中，然后随著环境pH值的变化沈积在细胞内部，将细胞的形状和轮廓给保存下来。
