Australia, about 39 million years ago, was completely separated from Antarctica as a separate continent. Because of the early separation from the continents, the evolution of species is slow, so today there are many strange animals living in Australian land;
For example, the platypus, an oviparous mammal, a kangaroo, a high jumper in mammals. And the protagonist we want to talk about today, the Australian stupid cute animal - wombats.
Wombats (Phascolomidae), a species unique to Australia, are common names for 3 species of animals in 2 genera of the Wombat family. The three species of wombats are the Queensland Fursned (Nose) Wombat, the South Australian Fursnock Wombat and the Tasmanian Wombat. Don't look at wombats look like bears, if you want to talk about blood, they are still related to kangaroos, koalas and other animals.
Although the appearance of wombats is somewhat similar to that of bears, their living habits are closer to rodents, and they like to eat grass, burrow, and are good at digging. As a result, wombats have muscular, short, and powerful limbs that allow them to dig holes in the ground.
Adult wombats can be up to one meter long and weigh up to 35 kilograms. However, this furry, chubby, seemingly strong and fierce animal, like their relative koalas, is stupid and cute:
<h1 class="pgc-h-arrow-right" > can pull out a cube poop</h1>
Unlike other animals, wombats' poop is not a long, rounded strip, but a cube about 2 centimeters wide.
Patricia Yang, a postdoctoral researcher in mechanical engineering from the United States, has studied the causes of wombat cube poop. Patricia Yang and the research team used mathematical models to restore the pattern of wombat gastrointestinal peristalsis. It was found that the gastrointestinal peristalsis of wombats was not a uniform horizontal wave forward, but irregular peristalsis.
In addition, the elastic deformation of the end of the wombat's stomach is only 20%, so the stool will be squeezed into small cubes with edges and angles at the end. Moreover, the digestives of wombats contain a large amount of plant fiber, which is more conducive to them shaping the poop into a cube in the stomach and intestines.
It is worth mentioning that wombats can pull 4-8 poop at a time, and more than 100 poop a day. The reason they pull so much poop is related to the role of these poop.
Wombats can be used to mark territory in squares, and they have poor vision but a keen sense of smell. Wombats will collect poop, pile them around the territory, and use the smell of poop to tell other wombats: This is my chassis; at the same time, the smell of poop is also a "signpost" for wombats to find a mate.
<h1 class="pgc-h-arrow-right" > like to feed their babies poop</h1>
Like many Australian animals, female wombats have a nursery pouch on them.
However, because the life habit of wombats is to like to plan the pit, in order to avoid the soil in the nursery bag when the pit is planed, let the baby eat the soil. Therefore, in the process of evolution, wombats have made their nursery bags become backwards.
Then the baby wombats who stay in their mother's nursery bag will face a very embarrassing situation: when the mother pulls the poop, those cubes of the cube will most likely split the head and cover the face on their own faces, which is the real to the shower.
Perhaps the baby wombat should be thankful that its mother will not be thin.
As we mentioned above, the cubes pulled out by wombats can be used to mark territory and find mates. In addition, these cube poop also has a role, that is, it can be fed to baby wombats!
Yes, wombat mothers feed their own poop to their babies. Because the metabolism of wombats is very slow, it takes 14 days to digest the food eaten into the stomach, and it may not be digested cleanly.
Wombats that usually love to eat grass roots and bark will have some bacteria in the stomach that specialize in digesting plant fibers, but the baby wombats lack this bacterium. Therefore, wombat mothers often feed their babies poop and eat, which is not only conducive to digestion but also supplements the bacteria that digest plant fibers for the baby wombats.
Like to give the baby poop this point, wombats and relatives koala exactly the same, not a family does not enter the door ah.
<h1 class="pgc-h-arrow-right" > short-headed short-legged "iron" butt</h1>
If there is one sentence to describe the physical characteristics of wombats, it is a short-headed short-legged "iron" ass. Wombats have flat skulls, shorter faces and noses, and stubby but powerful limbs.
The point is: the "iron" ass of the wombats.
Wombats usually look warm and swallow, but once they encounter predators, they can also explode at an astonishing speed, at a speed of 40 kilometers per hour, running wildly for 90 seconds.
Since wombats generally range near their own caves, this time is enough for them to return to the cave. When the wombats run back to the cave, they will not go into the depths at the first time, but will stop at the cave door to show only one butt, because the ass is their "weapon" to attack and protect themselves.
Wombats have a layer of hard bones on their butts and thick fur, and they burrow their heads inwards and buttocks outwards, and predators are helpless, after all, almost no animal can gnaw on the wombat's "iron butt".
If the predator is not spared, blocking the door of the house and not leaving, the wombat will use its own "trick" - to "pinch" the enemy's head with its butt.
They will first lower their own ass, lure predators deeper and stick their heads above their butts. Then, with all the strength of his body, he violently lifted the "iron ass" upwards. Usually, the first "Tetsujiri Strike" of the wombat is powerful enough to explode the skull of a predator.
For example, a biologist once found the body of a tiger ferret (one of the natural enemies of wombats) with a broken skull at the door of the kangaroo's cave, which is the following unlucky child:
What if you don't kill your natural enemies at the first time? The wombat lifted his ass so hard that he squeezed the head of the predator into the wall of the cave, suffocating the enemy alive.
postscript
Currently, almost all of the world's wombats are concentrated in Australia. In the protracted mountain fire the year before, the wombats also passively protected many small animals, and those small animals ran into the wombats' mountain caves and escaped the fire that destroyed the world.
Although wombats have a strong ability to protect themselves, the Queensland fursned (nose) wombats are currently critically endangered. Australian biologists expect them to become extinct in the future.
