举例来说，有羽状触手的海洋动物海百合，就可追溯到4亿多年前。

For instance, sea lilies, marine animals with feathery arms, date back more than 400 million years.

同为海百合纲的海羽星是一种高度灵活的海星形式。

This species, also known as crinoids, is a highly mobile form of sea star.

令海百合爱好者担心的是，最新的研究表明，螃蟹们正在爬上大陆坡。

Worryingly for sea-lily lovers, the latest research suggests the crabs may be creeping up the slope.

在贵州省关岭地区上三叠统瓦窑组地层中发现了保存完好的海百合化石群。

Recently a rich and well preserved crinoid community has been found in the Late Triassic Wayao Formation in Guanling County, Guizhou Province, China.

这种气候造就了不同寻常的海百合群落、海蛇尾、巨大的海带和只有薄壳的软体动物。

The result is an unusual bunch of sea lilies, brittle stars, giant ribbon worms and molluscs that are armoured only with thin, soft shells.
