Kangaroo in Australia

Kangaroo is the national symbol of Australia. It can be seen in a lot of Australian products, souvenirs, and company and organization logos.

It is somehow curious to know why, of all the animals in Australia, why the Kangaroo as the national emblem? The kangaroo is considered to be one of the most interesting animals on the planet.

Although kangaroos are popular and known as the mammal with a pocket on the tummy all over the world, still very little is known by most people.

These marsupials are endemic to the land of Australia. Although they have a short life span of four to six years and are almost always killed in traffic or hunting, the kangaroos have managed to stay alive and thrive in abundance all over Australia.
Belonging to the Macropodidae family, or animals with large feet, kangaroos are the one and only big animals that use jumping or hopping as its primary way of moving about. It can move as fast as 70 km/hour if it needs be.

But this is only possible with short distances. Its normal and comfortable speed is at around 25 km/hour.



However, it can carry on a 40 km/hour speed for a two-kilometer run. Kangaroos are pushed to a higher speed not by predators that go after them, as they only have a few natural predators, but by the need to cover far distances in search of food.

So, it is more for economical reasons than for survival purposes. The roos, as they are colloquially called, have a lot of kindred in the Macropodidae family. There are around 50, although smaller, species of cousins. Of these, there are four that are larger and more popular and more recognizable as kangaroos.

And they are: the Antilopine Kangaroo, which lives in the far-northern part of Australia; the Eastern Grey Kangaroo, which as the name suggest, lives in the eastern part of the land; the Red Kangaroo, the largest of the family and boldly roams the arid center of Australia; and lastly, the Western Grey Kangaroo, which dominates the southern area of Southern and Western Australia.

What is most interesting in Kangaroos is their child-bearing. The female kangaroo, which is known in various names, is eternally pregnant.

How is this possible? Well, the female gives birth to its “joey” (baby kangaroo) when it is only 31-36 days of its gestation.


The newborn joey is released to the pouch, where it sucks on the mother’s teat until it grows big enough to jump out from time to time. This development takes about nine months.

It will still come back to the pouch and stay until the 18th month, when it can totally separate from the pouch and not return again.

Now, while the baby joey is already in the pouch, the mother is again sexually ready to conceive another baby.  Hence, when the mother mates while she is still nursing a joey in her pouch and still technically pregnant, it is possible that she will get pregnant again.

The interesting part is that the female, or the doe (flyers or jills) as it’s sometimes known, has the ability to delay the development of the new joey until the first joey is old enough to get out of the pouch. This is not a problem at all because joeys develop fast and can be ready to be up and about in 190 days.
