The geometric shape of the wombat’s “poop” already has an explanation

Sydney (Australia) / An international team of scientists discovered that the exceptionally uniform geometric shape of the droppings of the vombat, a native Australian marsupial known as a wombat, forms in the intestines and not at the exit point as previously thought, according to a published study.

“Common wombats (Vombatus ursinus) are famous for producing distinctive cube-shaped poop. This ability to form relatively uniform and clean feces is unique in the animal kingdom, “said Scott Carver of the University of Tasmania in a statement from this Australian institution.

Carver made the accidental discovery while dissecting a wombat carcass as part of his main research on treating scabies disease in these short-legged, bear-like marsupials.

Explaining the results of this research published in Soft Matter magazine, Carver explained that wombats place their feces “at prominent points in their territory, such as around a rock or a log, to communicate with each other.” “Our research found that these cubes form in the last 17% of the colon,” he detailed.

The team of Australian and American scientists, who were awarded the Ig Nobel satirical prize for “research that makes you laugh then think” in 2019, discovered through a combination of laboratory tests and mathematical modeling, that there are two regions rigid and two more flexible around the gut of the wombat.

The study

The combination of desiccation of stool in the distal colon and muscle contractions form the size and regular corners of stool, the University of Tasmania statement said.

The wombat’s intestine is approximately 10 meters long, that is, 10 times the length of the body of a typical wombat, and its digestive process takes four times longer than in a human being to extract all the possible nutritional content, as well as its water, so their droppings are drier than a man’s.

Carver said the discovery highlights an entirely new way of making cubes – inside a soft tube – and that the results could be applied to other fields, such as manufacturing, clinical pathology and digestive health.

“Cubing can help us understand the hydration status of wombats, as their feces can appear less cubic in more humid conditions. It also shows how intestinal stiffness can produce smooth sides as a feature of the pathology, ”said the ecology expert from the University of Tasmania. (February 4, 2021, EFE / PracticaEspañol)
