Wombats deposit poo outside their burrows and on the tops of rocks and logs, where they are more easily found by other wombats. The distinctive shape is an advantage as the flat sides of the cubes ensure they do not roll off their precarious locations.
But how is cubic poo produced?
Wombat poo is cubic, not because the wombat has a square-shaped anus, but because it has a very long and slow digestive process, typically 14 to 18 days, which allows the digestive matter to become extremely dry and compacted. The wombat also has a very long digestive tract, allowing it to absorb the most nutrients and water from its food. The first part of their large intestine contains horizontal ridges that probably mould the poo into cubes, whereas the last part of the large intestine is relatively smooth, allowing the cubic shape to be maintained.
