Everyone knows that raccoons are also called "crisp noodles", so what is "convenient bear"?
When it comes to this interesting place in Australia, the average person will think of these three animals: kangaroos, koalas (koalas), and platypus. What other marsupial animals can you think of, today we come to talk about the name and the small editor and the same family and there are marsupial animals - wombats.
Although the difference between the wombat and the koala is one word, the two brothers have parted ways tens of millions of years ago, one has learned to go up the tree, the other has learned to escape.
As for why it is also called a convenient bear, in fact, as the name suggests, it is the only one in history! into a cube shape! Creatures! No mistake, pulling out is square,there is no pinching or pressing, nor is there a square anus.
There are 2 genera and 3 species of animals in the wombat family, and today we mainly introduce the largest of the three species of wombats, the Tasmanian wombat (Vombatus ursinus).
Adult Tasmanian wombats are 80–130 cm long and weigh 17–40 kg; they reproduce every two years for a gestation period of 20–30 days and give birth to 1 litter each time. The cubs stay in the bag for 5 months, and when they leave the bag, they generally weigh between 3.5 kg and 6.5 kg. The average lifespan of Tasmanian wombats in the wild is 15 years, and the average lifespan in captivity is 20 years.
Don't look at the wombats grow big and are not light, but they are completely vegetarian, they feed on grass and wild vegetables, and the digestion process of wombats is very slow, and the food takes about 14 days.
Usually, it is very slow, but when encountering danger, the escape speed can reach 40 km / h and maintain for up to 90 seconds.
Each wombat has its own range of motion and foraging space. In one area, a tunnel system is excavated, which is 2 to 20 m long and has many side tunnels.
Usually, only one entrance to the cave exists, although they may form a smaller entrance for escape. Tammanian wombats generally don't move easily, and unless influenced by external factors, they will spend their entire life in a cave.
It is worth mentioning that wombats' broods are not opened forward like kangaroos, but backwards, which avoids the soil falling into the pouch when the female wombats dig holes.
At the Fluid Mechanics sub-session of the 71st Annual American Physics Conference, Patricia M. Thompson, a Chinese-American scientist in The Woodland Lab at Georgia Tech, W. Bush, was appointed to the U.S. Patricia J. Yang published the report,
Patricia Yang said, "I've never seen anything so weird in biology, and it appealed to me. This is a mystery. I didn't even believe it was true at first, I googled it and saw a lot of stuff about wombat cube poop, but I was always skeptical. ”
They studied two Tasmanian wombats killed in a car accident and found that the gut was the heart of shaping the square poop.
Wombats, like all other mammals, have a fluid flow of digestion residue through 92% of the intestines before they begin to dehydrate to form small cubic particles. The difference is that on the cross-section, the large bowel structure of the wombat is not uniform. This change in shape is due to the elastic characteristics of different orientations within the intestinal wall.
The researchers wrote in a recent paper abstract, "By emptying the intestine and stuffing long inflated balloons, we found that the local stresses on the cube ranged from 25 percent at the corners to 75 percent at the edges." That is, the intestines tend to stretch in the intestinal wall to promote the formation of cubes. The paper was published at the annual meeting of the Fluid Dynamics Branch of the American Physical Society.
Wombats are notoriously poor in vision, so they rely on odor markers for communication. Wombat poop is often used as a geographical marker so that the same kind can know who owns a territory.
After all, the square poop does not roll, it is easy to stack, so there is no need to worry about your poop running elsewhere.
This new study is not only an academic survey study, but also has the potential to lead to quite practical results. Patricia Young says this approach can be applied to our current manufacturing processes.
"There are currently only two ways to make cubes: molding and cutting. Now, we have a third method. "It's going to be a really cool way to apply to the manufacturing process — that is, how to make cubes using soft tissue, not just molding." ”

Although Tasmanian wombats are not in CITES and are not listed in the IUCN Red List, another member of the genus, the Queensland Wombats (Lasiorhinus krefftii), have just over a hundred in the world, with CITES rated I and critically endangered on the IUCN Red List.
Queensland Fur kiss wombat
Queensland Fursnock Wombats were widely distributed 100 years ago in New South Wales, Victoria and Queensland, but are now limited to 3 square kilometres of Epping Forest National Park in Queensland. In 2000, a two-metre-high protective fence was built in the park, but due to its small number, no artificial breeding or migration work was carried out.
I hope that this lovely species can flourish on the earth. Don't be history in a museum.
