Wombats produce cube-shaped poop.

If any one of us were to poop out a perfect cube, you’d likely be contacting a gastroenterologist to get checked out ASAP. But for wombats, cube-shaped poop is the norm. These marsupials produce up to roughly 100 six-sided excretions each day, which they often place to mark their territory.

These poop cubes are created during a typical wombat’s lengthy digestive process, which takes four times longer than that of humans. During this period, each bit of feces experiences upward of 40,000 contractions, with each one subtly pressing on the poop and forming it into a dicelike shape. That long duration also sucks all the moisture and nutrients from the poop, resulting in a more durable brick of excrement that retains a harder texture and more precise shape after emerging.
