英文早点 | 1125_方形粑粑怎么拉出来的？科学家告诉你

动物王国中粑粑最特别的还要属袋熊，这个小家伙的粑粑居然是方块状的，而且它一夜间就能生产出80-100个这样的“小方块”！袋熊恰恰就是领地意识极强的一种动物，它们用自己方块状的粑粑标记自己的领地，以避免冲突。粑粑肯定不能拉在家里！袋熊会将粑粑排泄在洞口、岩石上、树上，总之能让其他袋熊找到就对了。而此时，粑粑的形状也凸显了它的优势：方块状的粑粑不会滚！来！滚！去！

The wombat, native to Australia, produces about 80 to 100 cubes of poop each night. The wombat's cubed faeces is a trait that's unique in the animal world, the researchers said, as cubes are usually created by cutting or molding.

The wombat takes about two weeks to digest its food and researchers found that as faeces move into the final 8% of the intestine, it changes from a liquid-like state into solid matter. At that stage the dung takes on the shape of separated cubes measuring about two centimeters in length.
