How Wombats Produce Cube-Shaped Feces

Quick fact

Wombats are the only known animal species that produce cube-shaped feces. This is due to the unique structure and function of their intestines, specifically the varying elasticity and muscle contractions in the colon's final section, which mold the waste into cubes.

Why this is interesting

Imagine picking up a pile of animal droppings and finding perfect little cubes—nature's own dice. Wombats, the burrowing marsupials of Australia, are the only animals on Earth that produce cube-shaped poop. How on Earth does that happen?
