Wombats are the only known animal to produce cube-shaped faeces. This Australian mammal's unique intestinal shape and flexibility allow it to mould its excrement into cubes. The cube-shaped droppings may be used by wombats to mark their territory, as they are less likely to roll off rocks or logs. Wombats can excrete four to eight scat pieces at a time and may defecate up to 100 cubes a day.

What You'll Learn
Wombats are the only Australian animal that poops cubes
The wombat's intestine can be compared to a rubber band, with two ends kept slightly taut and the centre section drooping. The stiff and elastic parts of the intestine contract at different speeds, creating the cube shape and sharp corners. This process is unique to wombats and is not found in other mammals, where the wavelike peristalsis of intestinal muscles are consistent in all directions.
Researchers have dissected wombat intestines to understand better how cube-shaped poop is produced. They found that the wombat's intestinal wall has elastic-like properties, with regions of varied thickness and stiffness. By creating a 2D mathematical model, they simulated how these regions expand and contract with the rhythms of digestion. The softer intestinal regions squeeze slowly and mould the final corners of the cube.
It is speculated that wombats evolved cubic poop to mark their territory. The flat-sided faeces are less likely to roll off rocks and logs, which are common perches for wombats. The cube shape may also assist in poo-stacking, increasing the surface area for the dispersal of the animal's scent, which can convey social messages or reproductive status.

Cube-shaped faeces are the result of the wombat's intestines
Wombats are the only animals known to produce cube-shaped faeces. Their intestines are approximately 33 feet long, which is ten times the size of the wombat itself. This results in a much longer digestion process than in humans, producing drier faeces as all nutrients and water are extracted from the food.
The wombat's intestines contain varied thicknesses and stiffnesses, with stiffer portions contracting faster than softer regions. The softer intestinal regions mould the final corners of the cube. This process is unique to wombats, and the cube-shaped faeces may assist in poo-stacking to mark their territory.
To understand this process better, researchers dissected wombats and examined the texture and structure of their intestinal tissue. They discovered that the wombat's intestines contract over several days, squeezing the faeces as nutrients and water are removed. The distinct shape of the intestines and the varied contractions mould the cube-shaped faeces.
Scientists suspect that the cube shape evolved to allow wombats to mark their territory effectively. The flat-sided faeces are less likely to roll off rocks and logs, which are common perches for wombats. This territorial marking may also be a form of communication with other wombats or a way to attract mates.

The shape prevents the poop from rolling off rocks
Wombats are the only known animal to produce cube-shaped faeces. They are native to Australia and are short-legged, burrowing marsupials. The cube-shaped poop is a result of the shape and flexibility of the wombat's intestines.
The mystery of how wombats produce cube-shaped faeces has been a long-standing one. Scientists have only recently discovered the cause of this phenomenon. By examining the wombat's intestinal tissue, researchers found that the organ expands and contracts during digestion, eventually squeezing out the excrement. The wombat's intestine can be likened to a rubber band with two ends kept slightly taut and a drooping centre. The stiff and elastic parts of the intestine contract at different speeds, creating the cube shape and corners.
The unique shape of wombat intestines, with their varied thickness and stiffness, plays a crucial role in forming the cube-shaped faeces. The stiffer portions contract faster, while the softer regions mould the final corners of the cube more slowly. This process results in the distinct, sharp-cornered cube shape.
One theory suggests that the cube shape of wombat faeces serves a functional purpose. Wombats often climb up on rocks and logs to mark their territory. The flat sides of the cube-shaped faeces prevent them from rolling off these elevated perches. This allows wombats to effectively communicate with other wombats and mark their territory.
The cube-shaped faeces of wombats have intrigued scientists and sparked curiosity, leading to a better understanding of wombat biology and behaviour.

Cube-shaped poop may assist in communication with other wombats
Wombats are the only animals known to produce cube-shaped faeces. Bare-nosed wombats (Vombatus ursinus) can excrete four to eight scat pieces at a time and may defecate up to 100 cubes a day. These scat pieces are placed around their territory, possibly to communicate with other wombats or attract potential mates.
Wombats have poor eyesight, so they rely on their sense of smell to communicate with each other. The six-sided structure of wombat faeces allows for a greater surface area to increase the dispersal of the animal's scent, which can convey social messages or reproductive status. The cube shape also prevents the faeces from rolling away, ensuring that the scent message remains in place.
The cube shape is formed by the wombat's intestines, which are much longer than those of other mammals and have unique elastic-like properties. The wombat's intestines have stiffer and softer regions that contract at different speeds, moulding the final corners of the cube. This process also removes water from the faeces, making them drier and harder, and thus more capable of retaining their cube shape.
The shape of wombat faeces may also be related to their health. According to David Hu, a biomechanics researcher at the Georgia Institute of Technology, captive wombats tend to have less cubic faeces than wild wombats, suggesting that the squarer the poop, the healthier the wombat.

Cube-shaped poop may help wombats mark their territory
Wombats are the only known animal whose faeces are shaped like cubes. Bare-nosed wombats (Vombatus ursinus) can excrete four to eight scat pieces at a time and may defecate up to 100 cubes daily. The cube-shaped poop is formed at the end of the wombat's digestive process.
The cube-shaped poop is a result of the wombat's intestines. The wombat's intestines are approximately 33 feet long, which is about ten times the size of the wombat itself. The intestines have varied elasticity, which helps the wombat sculpt its scat into cubes. The stiffer portions of the intestines contract faster than the softer regions, moulding the final corners of the cube.
The cube-shaped faeces may help wombats mark their territory. Wombats deposit their droppings on top of rocks or logs as territory markers, sometimes forming small piles. The flat-sided faeces are less likely to roll off these high perches. The cube shape may also assist in stacking, allowing for a greater surface area to increase the dispersal of the animal's scent, which can convey social messages or reproductive status.
Scientists suspect that the wombat evolved its unique trait of producing cube-shaped faeces to mark its territory effectively. The cube-shaped poop that doesn't roll away easily may help wombats communicate with each other and attract mates.

Frequently asked questions
Wombats are the only known animal to poop cubes.
Wombats' intestines contract in different ways due to varying levels of thickness and stiffness in their intestinal tissue and muscle. The stiffer portions contract faster, while the softer portions mould the corners of the cube more slowly.
One theory is that the cube shape prevents the poop from rolling away when used to mark territory on top of rocks and logs. Another theory is that the six-sided structure increases the dispersal of the animal's scent, aiding communication.
Bare-nosed wombats can excrete four to eight scat pieces at a time and may poop up to 100 cubes a day.
Wombat cube poops are approximately 2 centimetres or 0.8 inches in size.
