Plankton diversified, followed by a host of suspension feeders like certain types of brachiopods, rugose corals, and bryozoans.

浮游生物多样化，随后出现大量悬浮饲养者，如某些类型的腕足动物、皱纹珊瑚和苔藓虫。

The Ordovician period also saw the advent of more active suspension feeders, like the giant, filter-feeding anomalocarid Aegirocassis.

奥陶纪时期还出现了更活跃的悬浮式捕食者，例如巨大的滤食性奇虾 Aegirocassis。

It looks like some of the crinoids might've taken a different approach to feeding - instead of staying face-up suspension feeders, they went face-down.

看起来有些海百合可能采取了不同的进食方式——它们不再是面朝上的悬浮式喂食器，而是面朝下。
