如果你对可爱的袋熊有所了解，你会知道袋熊是地球上唯一能拉出方形便便的生物。多少年来，科学家一直无法弄明白袋熊为什么能拉出立方体的便便，而今他们终于找到答案了。

Despite having round anuses like all other mammals, bare-nosed wombats2 do not produce round pellets, tubular coils or messy piles; they are the only creature on Earth that poops cubes.

尽管和其他所有哺乳动物一样长着圆圆的肛门，但是毛鼻袋熊拉的便便却不是圆球状、螺旋状或乱糟糟的一堆，它们是地球上唯一拉方形便便的生物。

Wombats, marsupials native to the grassy3 plains and eucalyptus4 forests of Australia, are among the most adorable animals in the world, but to animal experts they have been a tough-to-solve mystery for a very long time. And it has all been because of their poop. You see, bare-nosed wombats have the unique ability to produce up to 100 distinctive5, cuboid pieces of poop every day. Now, researchers say they have uncovered how the wombat1 intestine6 creates this unusually-shaped excrement7.

居住在澳大利亚草原和桉树林里的有袋哺乳动物袋熊是世界上最可爱的动物之一，但是很长时间以来它们对于动物专家来说都是难解的谜。这都是因为它们拉的便便。要知道，毛鼻袋熊拥有一项独特能力，每天都能拉多达100个与众不同的立方体便便。现在，研究人员声称他们已经找到了袋熊便便如此特别的原因。
