diatom

It may lie in the shell of a single-celled, 100-million-year-old life form called a diatom..就在一种拥有一亿年历史，称之为硅藻的单细胞植物的外壳里。

The colorful effect is due to the diatom's silica cell wall, which encases the organism like a glassy shell..它的五颜六色效果是由于硅藻的像玻璃外壳包围着机体的二氧化硅细胞壁。

Called Thalassiosira trifulta, the diatom was discovered as part of an ongoing project to catalog animal diversity on the Korean Peninsula (map)..这种属于海链藻属的硅藻是在科学家们在朝鲜半岛调查当地的动物多样性的时候被发现的。
