Either way, the Paleozoic Era continued to be dominated by the crinoids and other echinoderms.

无论哪种方式，古生代继续由海百合和其他棘皮动物统治。

Paleontologists wonder whether the ability to move around might've helped starfishes fare better than the stationary crinoids did.

古生物学家想知道四处移动的能力是否比静止的海百合更能帮助海星生存。

If anything, the eocrinoids and crinoids with stalks were moving away from the low-profile body plan of a starfish.

如有什么同的话，那就是带有茎的海百合和海百合正在远离海星低调的体计划。

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同的进食方式——再是面朝上的悬浮式喂食器，而是面朝下。

Modern starfishes move using their tube feet in a way that's similar to what crinoids do to waft food into their mouths.

现代海星使用管脚移动，其方式类似于海百合将食物送入嘴中的方式。

Crinoids became the most abundant echinoderms of the Ordovician, and some were the ancestors of today's stalkless feather stars and stalked sea lilies.

海百合成为奥陶纪最丰富的棘皮动物，有些是今天无柄羽星和有柄海百合的祖先。

And crinoids are still around, too, but their species number in the 600s, in contrast to the 6000 known species that've lived throughout Earth's history.

海百合也仍然存在，但的物种数量只有 600 种，而地球历史上已知的物种数量为 6000 种。

Sea levels were high, and the continents were surrounded by vast, shallow seas, full of exotic creatures like rugose corals, crinoids, and jawless fish.

海平面很高，大陆被广阔的浅海包围，充满了奇异的生物，如长皱纹珊瑚、海百合和无颌鱼。

Including the similar-looking and closely related group - the crinoids, also called sea lilies - which showed up and diversified into many species with different suspension-feeding body types.

包括外观相似且密切相关的群体——海百合，也称为海百合——出现并多样化为许多具有同悬浮喂养体型的物种。

But we still need more fossil evidence to help us figure out whether Cantabrigiaster really was a transitional animal between crinoids and sea stars or not.

但是我仍然需要更多的化石证据来帮助我弄清楚 Cantabrigiaster 是否真的是海百合和海星之间的过渡动​​物。

But starfishes and their skinny-armed cousins called the brittle stars made it through, along with a few crinoids, sea cucumbers, and sea urchins – the groups we still see today.

但是海星和被称为海蛇尾的瘦臂表亲以及一些海百合、海参和海胆——这些我今天仍然能看到的群体——成功了。

So, as odd as the starfish body plan seems, something about it was successful -- from their ancient bilateral ancestors, to the radial crinoids with their upward-facing arms, to the predatory, downward-facing starfish.

因此， 尽管海星的体计划看起来很奇怪，但的某些方面是成功的——从古老的双侧祖先，到手臂朝上的放射状海百合，再到捕食性的、面朝下的海星。
