There were also creatures like Ottoia, a segmented worm with an extendable mouth for slurping up small prey.

还有像 Ottoia 这样的生物，这是一种分段的蠕虫， 嘴巴可以张开， 可以吞食小猎物。

They may have evolved from small thick-skinned segmented worms like spriggina, which I gotta say do seem to share a family resemblance.

它们可能是从像 spriggina 这样的小而厚皮的分段蠕虫进化而来的，我得说这似乎确实具有家族相似性。
