Bear's close relatives?
No, don't get me wrong!
As we all know, koala also has several aliases: koala bear, koala bear. But in fact, koalas have nothing to do with bears. The family of bears belongs to the order Carnivora, while the koala belongs to the order of pouches. The reason is called "bear", probably because the koala round roll posture, and furry bear is just as cute!
"have you ever seen a bear we love so much?"
Male and female
Male koala howls in the middle of the night
Koala breeding season is usually from August to February, during which the male koala activity will be more vigorous, often between 10:00 and the next day at 4 am to make a roar. This wild roar is one of the main ways to help us distinguish between male and female koalas.
"Wow, mom and dad are at home today!"
brood pouch
Mom koala, too.
Pouch is not the exclusive kangaroo, koala mother also has a baby bag oh. However, unlike the kangaroo's pouch, koala's pocket is not on the belly of the TA, but on the back, and the opening is downward. This form of bag, on the one hand, easy to climb in and out of the small koala, on the other hand, also ensure that the inside dirt can automatically fall out.
"Mom's back is comfortable."
High specificity
Eat only one kind of food in a lifetime
Koalas are "absolutely picky" about food, eating only one food-eucalyptus leaves-and eating only a few eucalyptus leaves in their hometown, which can eat 0.5 kilos a day. Australia has more than 500 species of eucalyptus trees, only more than 40 species of eucalyptus leaves can be used for koala food, of which only a dozen are koala's favorite. The consequences of picky eating, is that they often indigestion, irritable can only gnaw the soil to help digestion.
"trying to steal my eucalyptus leaves? No way! "
Sleep 22 hours
Because the food is toxic.
Just now, koala only eats eucalyptus leaves every day, and hardly drinks water. In fact, eucalyptus leaves are very difficult to chew and do not have much nutrition, for other animals, there is also toxicity. Koala sleeps 18 to 22 hours a day, either because eucalyptus leaves do not support the amount of heat that TA needs for a day, and TA takes time to degrade toxins in food. Choose the consequences of eating, my friends!
"I'm sorry, I'll get some sleep, and I'll talk in 20 hours!"
It's not lazy.
Holding the tree to cool down.
When it comes to koala, the first picture in mind is the cute look of koala holding a tree. Think we koala baby are too lazy to move? No! Most of the year in Australia is dry and hot, and the temperature of the trunk is often more than 5 ℃ lower than the air, so the "lazy" koala on the tree is actually cooling!
"it's so hot today, baby."
as nimble as an escaping hare when going into action
You can run to catch a SUV.
Used to watch koala lazily holding branches to nibble leaves, can you imagine TA can still run up? Right! Koala can not only run, but also run faster than rabbits! An Australian girl online PO a video of a koala running after her Land Cruiser on the road, at a speed that feels like it can get to the wheels of a Land Cruiser in minutes. Besides, koala can climb trees and swim, but it's hard to see.
"where is this place? Where's my eucalyptus tree? "
Little koala
Birth weight is only 5.5 grams
Koala is about 35 days pregnant, each child gives birth to only one small koala. The little koala, born less than an inch and weighing just 5.5g, climbed to her mother's back after six months in a pouch on her mother's back and lived on her mother's back when the cub reached one year old, living independently of her mother. 3-4 years of sexual maturity, The theoretical life span is about 20 years.
"hold on, let's go!"
Five fingers.
Like humans.
Koala's forepaws have five fingers, two of which are opposite to the other three, much like our thumbs, helping TA hold branches more easily and grab food. Koala's hind claws are even more peculiar, the second and third fingers are fused together, used specifically to comb hair! If it is a face-watching era, even our cute little koala, only four hours a day to wake up, but also evolved hair-trimmed claws.
"Thanks to the great paw, or it'll come to the end of the day!"
Fine fingerprint
Trying to fake it? Impossible!
Koala not only has fingers, but also fingerprints, oh, besides primates, the only animals with fingerprints. More interestingly, koala fingerprints are more elaborate than human ones and are difficult to tell under an electron microscope. So, afraid of forgery? Get a little koala to cover a unique poke.
"it's not easy to show you my paws, hey."
Such a cute koala, as an Australian national treasure, can be seen in most wildlife parks.
