The Australian marsupial can pass up to 100 deposits of poop a night and they use the piles to mark territory. The wombat takes about two weeks to digest its food and researchers found that as faeces move into the final 8% of the intestine, it changes from a liquid-like state into solid matter.

The team compared the wombat intestines to pig intestines by inserting a balloon into the animals' digestive tracts to see how it stretched to fit the balloon. Finding a more concrete answer, however, hasn’t been easy. The feces is typically placed in piles to better communicate, and the cubic shape prevents droppings from rolling away. Earlier this year, Patricia Yang, a researcher at the George Institute of Technology who specialises in bodily fluids, started to look into the topic more closely after hearing about it at a conference.

Wombats often arrange these cubes into mounds that mark their warren territories, essentially laying bricks straight from their bums. But neither of those hypotheses turned out to be the case. "We don't know what that information they're sharing is, but it might be something about mating, it might be something about general advertising about who's in the area.". To probe the intricacies of wombat poop, Yang and her colleagues examined the digestive tracts of two wombats that were euthanized after road collisions in Australia.

Yang observed two distinct ravine-like grooves, where the intestine is stretchier, which she believes helps shape wombat faeces into cubic scat. An image of then eight-month old Derek the Wombat who was rescued from his mother's pouch after she was hit by a car in December 2015. That was a mystery," Georgia Institute of Technology's Patricia Yang said. Video. Through this study, they have disclosed the physiological processes involved in this unique digestive trick. By inflating the intestine with a long balloon, the researchers found that the wombats' intestine walls stretch unevenly, allowing for the formation of the cube shapes. Being dry helps the scats form more rigid shapes with sharper angles. The wombat, native to Australia, produces about 80 to 100 cubes of poop each night.

Now, a team of scientists has finally discovered the reason behind cube-shaped wombat poop.

The wombat's cubed faeces is a trait that's unique in the animal world, the researchers said, as cubes are usually created by cutting or molding.

“We currently have only two methods to manufacture cubes,” she said, explaining that humans either mold cubes from soft materials, or cut them from harder objects.

"The weird thing is that if you open up a wombat you actually find that the cubes become formed in the lower part of the intestine, before they exit the body," Carver said. Others just think that it has to do with the fact that in their dry habitat, wombat bodies are simply trying to extract every ounce of moisture from their food. At that stage the dung takes on the shape of separated cubes measuring about two centimeters in length. "We currently have only two methods to manufacture cubes: We mould it, or we cut it. Researchers, led by the Georgia Institute of Technology's Patricia Yang, said they have uncovered the digestive processes behind the mystery and. "We opened those intestines up like it was Christmas," said co-author David Hu, also from Georgia Tech, according to Science News. As for why wombats poop cubes, researchers suspect the shape allows the animals to pile their feces next to their burrows and in other places to signal their territories. “At first I thought they maybe have square anus, or maybe [the cube] forms right around the stomach,” she said. No zoos in North America had any, so Yang had the intestines of two roadkill wombats shipped from Australia. Wombats take the concept of “shitting bricks” quite literally, and are known to drop around 100 curiously cubic poops every night.

So Yang and the team expanded both wombat and pig intestines with a balloon to measure and compare their elasticities (or stretchiness).

The study's authors said the findings could have implications beyond the natural world, by helping to provide insight into new manufacturing techniques. pic.twitter.com/Q7C9erGyd8. Get six of our favorite Motherboard stories every day by signing up for our newsletter . But how the wombat produces the cubed shapes is a phenomenon that has puzzled many observers of the furry marsupial. The wombat's cubed faeces is a trait that's unique in the animal world, the researchers said, as cubes are usually created by cutting or molding. But even the initial findings imply broader implications for sectors such as manufacturing. Yang’s team mimicked the process by inserting balloons into the wombats’ intestines and blowing them up to observe the contours and flexibility of their digestive system. Meet 6 creatures that steal others’ looks, Joel Sartore, National Geographic Photo Ark.

Wombats are a burrowing animal native to Australia and perhaps best-known for being, well, podgy—and quite cute. She got the dead wombats from Scott Carver, a wildlife ecologist at the University of Tasmania, who froze the specimens before sending them to the US for further study. "In the built world, cubic structures are created by extrusion or injection molding, but there are few examples of this feat in nature," authors of the project. "The first thing that drove me to this is that I have never seen anything this weird in biology. To solve the puzzle, the team examined the digestive tracts of wombats that had to be euthanized following vehicle collisions in Tasmania, Australia. The study discovered that near the end of a wombat's intestines, the feces would morph from a liquid state into solid, separate cubic shapes.

Wombats are the only creatures to organically produce poop shaped like a cube.

Now we have this third method," Dr Yang said. “I didn't really believe it,” Yang says. She wasn’t sure what to expect when they arrived. One popular postulate is that wombats make cubes so that they can stack them to mark their territory, without the pieces rolling away. Despite having round anuses like other mammals, wombats do not produce round pellets, tubular coils or messy piles. .css-14iz86j-BoldText{font-weight:bold;}Scientists say they have uncovered how and why wombats produce cube-shaped poo - the only known species to do so. ". "The weird thing is that if you open up a wombat you actually find that the cubes become formed in the lower part of the intestine, before they exit the body," Carver said. "And that is what creates the edges and the cubing.". Are white women voters wavering on Trump? "It would be a cool method to apply to the manufacturing process," she suggested, "how to make a cube with soft tissue instead of just moulding it.

This, the scientists explain, resulted in 2cm (0.8in) cube-shaped poops unique to wombats and the natural world. "Wombats have really strong sense of smell that they use probably for communication," said University of Tasmania wildlife ecologist Scott Carver, who co-authored the study.

Now we have this third method," said Patricia Yang, lead author on the study and a postdoctoral fellow in mechanical engineering at Georgia Tech, in a statement.

On the fronts and backs, the feces run about one inch by one inch, and are around an inch and a half long.

In wombats, the faeces changed from a liquid-like state into a solid state in the last 25% of the intestines - but then in the final 8% a varied elasticity of the walls meant the poop would take shape as separated cubes. But there’s something you might not know about these adorable marsupials: Wombats are the only animals in the world that produce cube-shaped poo. Wombats solidify and sculpt the turds using the lopsided elasticity of the intestinal walls in the final tenth of the tract. On Sunday, the secret behind this square scat was revealed at the annual meeting of the American Physical Society’s Division of Fluid Dynamics in Atlanta, Georgia.

What she found to be more important was how the wombat intestines’ stretched. David Hu, a mechanical engineer at Georgia Tech and co-author of the study, said “we opened those intestines up like it was Christmas,” according to Science News. While this peculiarity has sparked much interest and debate, actual research into the intricacies of wombat scat has been scant. This territorial impulse could explain why these animals evolved to produce feces that can be easily modeled into stable kairns of poo.

The wombat, native to Australia, produces about 80 to 100 cubes of poop each night.

Researchers may have found the answer to a mystery in the animal kingdom: How do wombats produce poop that looks like cubes?

It is thought that the cubed shape of the poop means it is less likely that it will roll away, and is prominent for other individuals to notice and smell, Carver added.
