相比之下，水母的碳含量为体重的10%，而硅藻(是单细胞海藻，属常见的浮游生物)则为20%。

Jellyfish, by comparison, are 10% carbon, and diatoms (single-celled algae that are common in plankton) 20%.

再想想，这种单细胞的硅藻(网状硅藻属的硅藻)，是一种类型的海藻，放大了40倍后，显示了像“彩虹”那样的错综复杂五彩缤纷排列。

Think again. This unicellular diatom (diatom Arachnoidiscus), a type of algae, reveals an intricate rainbow pattern under 40x magnification.
