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。

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?

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。

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。
