What distinctive, geometric shape characterizes the scat produced by wombats?

Answer

Cube-shaped

Wombats possess a highly peculiar physiological trait resulting in cube-shaped scat. This unique morphology is a consequence of the varying elasticity of their intestinal walls, which causes the feces to form distinct rectangular segments as they dry. This characteristic is so unusual in the animal kingdom that it often serves as a key identifier for the presence of these stout, burrowing marsupials. The shape is hypothesized to assist in marking territory, as the cubes are less likely to roll away from prominent surfaces where they are deposited, aiding in scent marking across their range.
