Pearls contain a mixture of protein and calcium carbonate secreted by certain types of molluscs.

珍珠是某些类型的软物分泌的碳酸钙同蛋白质一起构成的混合物。

Most crocodilians, he reminded people, preferred to dine on fish or molluscs rather than farmers.

他提醒人们，大多数鳄鱼宁愿吃鱼或软物而不愿吃农夫。

What does it mean to think What equipment is needed to think? Do molluscs have such equipment?

什么叫做思考？进行思考需要什么器官？软物有这种器官吗？

In the Pantanal, there really is plenty for everyone, and it's all thanks to a mollusc.

在潘塔纳尔，食物真的很充这全都一种软物的功劳。

Of course, molluscs are vital links in the complex chain of life. - Hm.

当然 软物是复杂生物链中的关键链接 - 嗯。

There are more species of molluscs in the ocean than any other animal phylum.

海洋中软物种类远超其他物门。

Was it me and my mollusc friends, with our amazing mantles and single foot?

是我和我的软物朋友吗？ 我们有不可思议的外套膜和单？

Algae and plankton, corals and kelp, jellyfish, molluscs, crustaceans, fish  and whales… the abundance of life here equals any found on land.

藻类和浮游生物、珊瑚和海带、水母、软物、甲壳类物、鱼类和鲸鱼… … 这里的生命丰富程度可与陆地上的任何生命相媲美。

They were as two horns which the sluggish heath had put forth from its crown, like a mollusc, and had now again drawn in.

两个人好像是软物一般懒怠的荒原伸出来的一对触角，现在又把它们缩了回去。

Most of the main groups of the animal kingdom—arthropods, brachiopods, coelenterates, echinoderms, molluscs and even chordates, the branch from which vertebrates went on to develop—are found in the fossil beds of the Cambrian.

人们在寒武纪群落里发现了物王国的主要物集群，包括腕、、棘皮、软和脊索（脊椎物进化的分支）。

Several introductions of damaging insects have been attacked successfully by further introductions of critters that eat them—though this has not worked so well for voracious introduced molluscs called giant African land snails.

通过进一步引入以它们为食的小物，成功地攻击了几种引入的破坏性昆虫——尽管这对被称为巨型非洲陆生蜗牛的贪婪引入的软物来说效果不佳。

Their journey from small, passive molluscs to sleek, voracious predators took hundreds of millions of years of trial and error -- from developing shells to survive, to finally learning to thrive without them.

它们从小型、被的软物到光滑、贪婪的捕食者的旅程经历了数亿年的反复试验——从开发贝壳以生存，到最终学会在没有它们的情况下茁壮成长。

That encourages the growth of planktonic algae, and thus of everything that feeds on such plankton, or feeds on what feeds on them, including jellyfish, and also various molluscs and crustacea that loggerheads enjoy as an appetiser.

这有利于浮游藻类生长，因此也有利于以这些浮游生物为食的物，或以这些物为食的物生长，包括水母，还有各种各样的软物和甲壳物，这些都是红海龟的最爱。

But by the late Cambrian, one mollusc known as Plectronoceras had acquired a couple of adaptations that marked the beginning of a brand new form of transportation -- and a whole new kind of mollusk.

但是到了寒武纪晚期，一种被称为 Plectronoceras 的软物已经获得了一些适应性，这标志着一种全新的运输方式的开始——以及一种全新的软物。

In early fish-like vertebrates more than 500 million years ago; in a common ancestor of arthropods, such as insects, spiders and crustaceans, at around the same time; and then in the cephalopod molluscs around 300 million years ago.

在 5 亿多年前的早期类鱼脊椎物中；节肢物的共同祖先，例如昆虫、蜘蛛和甲壳类物，大约同时出现；然后是头类软物大约 3 亿年前。

His undoing began when a committee of the Royal Society-a committee of which he happened to be chairman decided to award him its highest honor, the Royal Medal, for a paper he had written on an extinct mollusc called the belemnite.

英国皇家学会的一个委员会——欧文恰好是该委员会的主席决定授予他最高的荣誉：英国皇家勋章，表彰他写的一篇关于一种名叫箭石的、已经绝种的软物的论文。
