Australia has many marsupials, such as kangaroos, kangaroos, bags, etc., wombats are also one of them, but the difference is that the pockets of other marsupials are open forward, and the bags of wombats are open backwards, so the difference is that wombats will not let their children eat soil when digging and digging holes, but such a structure also has drawbacks, that is, it will let their children eat, commonly known as a handful of and a handful of urine to feed the child up.
Like koalas , koalas , eat their mother's droppings as a child. This is because wombats and koalas are herbivores, and herbivores are usually unable to digest on their own organs, and can only help decompose and ferment the microorganisms in the stomach and intestines, and they can finally absorb the nutrients.
The wombats and koalas have fewer microorganisms that help digestion, either by eating the mother's digested feces to obtain microorganisms, or through the mother's feces to obtain nutrition, after all, the feces in the herbivores digestion is not complete, there are many nutrients, young wombats can get nutrition by eating feces.
Wombat droppings are also very special and square. In nature, animal feces, banana-type, oval-type, liquid-type, but never seen square, is the wombat's anus square? So you can pull out the square canon?
Scientists have also studied this magical square, and found that this square feces has become square when it passes through the anus of the wombat, and concluded that the intestines of the wombats will squeeze when they form feces, making the feces square.
Such a square cane also has a very important role for wombats.
Each wombat has its own territory, and the way they mark the territory is to rely on feces, so that other wombats smell and see such a wombat, and will understand that this is the territory of other wombats.
The second effect is to attract the opposite sex, when the wombat pulls the stick, it is usually stacked high, in order to prove the strength of its body, the higher the base to prove that its body is stronger, the stronger the attraction to the opposite sex.
In this way, the square can also prevent rolling, so that there will be no mistakes when marking their own territory, and even make it less convenient for the shell lang to steal the rice ball.
The iron belly that can stand up to the enemy
In addition to being able to pull out square sticks, wombats can also use weapons to vigorously attack enemies.
The wombat has many weapons, sharp claws used to plane soil, and "iron teeth and copper teeth" that can bite the bark, as well as its body length of 70-110 cm and a weight of 20-35 kg, such combat power can even run around with humans.
The most powerful weapon of the wombat is its ass, the fur on its ass is thick and hard, and there is a large piece of cartilage on its ass, even if the fur of the ass is broken, this cartilage can greatly protect the organs in its abdominal cavity.
When in danger, wombats will run back to their caves at a speed of 40 km/h (equivalent to 11 m/s) and use their heads inwards and butts outwards. If at this time, the enemy is still chasing after the wombat, or even chasing into the wombat's cave.
Then at this time, the wombat will lower its ass, so that the position above the body is vacant, so that the enemy thinks that there is an opportunity, do not know that this is a trap for the wombat, once the enemy climbs the wombat's ass, the wombat will immediately lift the ass vigorously, frantically attack the enemy's head, in order to kill the enemy.
In the end, the wombat is still the hero of the previous Australian fire! The fire raged mercilessly, and the wombat's cave became a refuge for many animals, as long as there was no threat to themselves, the cave borrowed wombats was not rejected. And the wombat's animals are widely accessible and can accommodate many small animals, because many small animals were saved, and the wombats are also known as the heroes in this fire.
