noun

卵生哺乳动物

A mammal that lays eggs and has a single urogenital and digestive orifice. Only the echidnas and platypuses are included in this group

Examples :

"While most mammals give birth to live young, the monotreme is unique because it lays eggs, like the platypus found in Australia. "

虽然大多数哺乳动物都直接生育幼崽，但鸭嘴兽和针鼹这类卵生哺乳动物 (luǎnshēng bǔrǔ dòngwù) 非常特别，因为它们像澳大利亚的鸭嘴兽一样，是产卵的。
