And their ability to live in the deep turned out to be what saved coleoids from extinction.

事实证明，它们生活在深海中的能力 使胶体免于灭绝。

Hematites, for example, was one of the earliest coleoids, and it had a cone-shaped shell inside its soft body.

例如， 赤铁矿是最早的胶状体之一，它的软体内部有一个锥形壳。

Armed with these adaptations, coleoids began to take advantage of a new niche: the deep sea.

有了这些适应性，珊瑚虫开始利用一个新的利基市场：深海。

So with the ammonites gone, when conditions improved, the coleoids rose up and took their place.

因此，随着菊石的消失，当条件改善时，莰石上升并取而代之。

They were the first coleoids Like Sphooceras millions of years before them, coleoids wrapped their soft mantles around their hard shells.

它们是最早的鞘状体， 就像数百万年前的 Sphooceras 一样，鞘状体将柔软的外套膜包裹在坚硬的外壳上。

Today, coleoids have colonized every marine ecosystem on the planet, and they play a vital role in ocean food webs.

今天， 胶状体已经在地球上的每一个海洋生态系统中定居，它们在海洋食物网中发挥着至关重要的作用。

But the coleoids were able to take refuge in the deep sea, and were no longer dependent on their shells.

但是蛲虫能够在深海中避难，不再依赖于它们的贝壳。
