Excrement Extraordinaire

The cute marsupial wombat
Has a distinction quite unique,
Only animal with cube scat -
The how and why researchers seek.
Innards of some wombat roadkill
Were found to have ravine like grooves,
Causing shaped corners to instill,
As through the gut the feces moves.
And related is climate dry
Where wombats in the wild do be.
The dryer scat, one reason why
Sharp angles could shaped rigidly.

Cubes in nature are very rare.
Wombats do poop in cubes to share.
