Why Wombats Poop Cubes: Scientists Reveal the Bizarre Intestinal Secret Behind Nature’s Strangest Shape

Wombats are the only animals that produce cube-shaped droppings. Scientists have discovered this unique trait is due to the wombat's intestine. The final section of their intestine has varying elasticity. This uneven structure, combined with slow digestion and efficient water absorption, shapes the waste into cubes. These cubes help wombats mark their territory effectively. This discovery bridges biology and mechanics.
