有一种极为怪异的动物,它是哺乳动物,但它是哺乳动物里最不称职的一员,因为它像爬行动物一样下蛋。并且它长得很难看,有着食蚁兽一样的脸,身上长满如豪猪一样的刺。这种动物就是针鼹。现存的针鼹总共有四种,其中一种鼻子比较短的针鼹生活在澳大利亚,叫作短吻针鼹。澳大利亚现流通的面值为5分硬币的背面即是一只短吻针鼹。其余的三种生活在新几内亚,都长着长鼻子,都叫作长吻针鼹。长吻针鼹是濒危的野生动物。
There is a very weird animal, it is mammals, but it is the most incompetent member of mammals, because it is like a reptile eggs. And it looks very ugly, with an anteater-like face, the body covered with thorns like Porcupine. This animal is an echidna. A total of four existing echidna, one of the shorter nose echidna living in Australia, known as short-echidna mole. The back of a 5-cent coin now circulating in Australia is a short-eared mole. The remaining three live in New Guinea, all with long noses, all called long-eyed mole. Long-eyed mole is an endangered wildlife.
