lay eggs

It is one of only two mammals (the echidna is the other) that lay eggs..它是仅有的两种产蛋哺乳动物之一。

Occasionally, hens lay eggs with imperfect shells or without shells altogether..有时候，母鸡产蛋要么壳不完美要么干脆没有壳。

The most amazing (and badass) characteristic of the komodo dragon is that the female can lay eggs that hatch without being fertilized by a male (this is called parthenogenesis)..而他们最令人叹为观止的特点是：科摩多巨蜥可以单性繁殖——即雌性科摩多巨蜥可以再未受精的情况下产蛋。
