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

无论哪种方式，古生代继续由百合和其他棘皮物统治。

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力是否比静止百合更帮助生存。

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

如果说有什么不同话，那就是带有茎百合和百合正在远离低调体计划。

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.

看起来有些百合可采取了不同进食方式——它们不再是面朝上悬浮式喂食器，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.

现代用管脚移，其方式类似于百合将食物送入嘴中方式。

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

百合成为奥陶纪最丰富棘皮物，有些是今天无柄羽和有柄百合祖先。

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.

百合也仍然存在，但它们物种数量只有 600 种，而地球历史上已知物种数量为 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.

平面很高，大陆被广阔浅包围，充满了奇异生物，如长皱纹珊瑚、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群体——百合，也称为百合——它们出现并多样化为许多具有不同悬浮喂养体型物种。

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.

但是我们仍然需要更多化石证据来帮助我们弄清楚 Cantabrigiaster 是否真是百合和之间过渡​​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.

但是和它们被称为蛇尾瘦臂表亲以及一些百合、参和胆——这些我们今天仍然看到群体——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， 尽管体计划看起来很奇怪，但它某些方面是成功——从它们古老双侧祖先，到手臂朝上放射状百合，再到捕食性、面朝下。
