鸭嘴兽介于哺乳类与爬行类之间，因为它仍然具备许多爬行动物的特征，如产卵，而这些特征在我们身上已经消失了。

And that puts them somewhere between mammals and reptiles, because they still maintain quite a lot of reptilian characteristics that we've lost, for instance they still lay eggs.

我的产业向我岂如斑点的鸷鸟呢。鸷鸟岂在她四围攻击她呢。你们要去聚集田野的百兽，带来吞吃吧。

Mine heritage is unto me as a speckled bird, the birds round about are against her; come ye, assemble all the beasts of the field, come to devour.
