Structurally speaking, you've got fibrous, cartilaginous, and synovial joints.

从结构上来说，你有纤维关节、软骨关节和滑膜关节。

As for cartilaginous fish, Conseil went on unflappably, they consist of only three orders.

至于软骨鱼类，康塞尔很冷静地又说，那就只有三目。

Their cartilaginous skeletons are less dense than bony ones and require less energy to move.

这些生理特质从4亿多年中进化而来它们软骨质的骨架比硬骨的骨架更轻。

Within the chameleon's mouth, a tongue muscle squeezes a series of concentric sheaths around a cartilaginous rod, storing elastic energy.

在变色龙的口腔中，舌肌紧缩软骨棒周围舌鞘，储存弹性能量。

Yes, of course. So which type of joint can you crack? Is it … a) fibrous? b) cartilaginous? Or c) synovial?

当然。那么你能掰响哪一种关节？是a)纤维性关节? b)软骨性关节? c)滑液性关节?

These are distant, cartilaginous cousins of sharks that live in the deep sea today.

这些是今天生活在深海中的鲨鱼的远亲软骨表亲。

In their wake, bony fish and cartilaginous fish like sharks and rays took over the oceans.

在它们的身后，硬骨鱼和软骨鱼如鲨鱼和鳐鱼接管了海洋。

Spoken like a true glutton, Conseil replied. But tell me, are you familiar with the differences between bony fish and cartilaginous fish?

这是讲究吃喝的人的一种分类法，康塞尔回答，请您告诉我，您知道硬骨鱼类和软骨鱼类之间存在的差别吗?

Several of these classes are specific types of fish, for example: jawless fish, like lampreys and hagfish, and cartilaginous fish, like sharks and rays.

这些纲类的一些便是鱼类，比如：无颚纲鱼形动物，像七鳃鳗、盲鳗和软骨纲鱼，像鲨鱼和魔鬼鱼。

If we look at the really successful features of sharks you've got to consider this cartilaginous skeleton – that's no bone in the skeleton.

如果我们研究鲨鱼真正成功的特征，你必须要考虑到软骨骨架——那是指骨架中没有骨头。
