Australia's Iconic Animal Kangaroo

He is not the only one with a bag to keep his young.

Did you know that Kangaroos only move forward, never backward?

And the kangaroo is an animal that has so many unique characteristics that make it an adorable but peculiar animal.

There are more than 60 different species and they are endemic or exclusive to Australia. But if you haven't visited this continent, you could mistake other close relatives like the Wallabi for this animal. 

They belong to the macropod family, which means big legs. 

The main species of macropods include:  

Eastern gray kangaroo 

Western gray kangaroo 

Red kangaroo 

Wallaby 

Wallaroo 

Forest wallabies 

Pademelons 

Tree Kangaroo (endangered)

The three species of Australian kangaroos you are most likely to meet are the eastern gray kangaroo, the red kangaroo, and the western gray kangaroo.

Not surprisingly, you find eastern gray kangaroos on the east coast of Australia and western gray kangaroos on the west coast of Australia.

The red kangaroo is the most common and you will find it throughout Australia, but mainly inland, away from coastal areas. For a long time it was not known that there were two different types of gray kangaroos. They look very similar but differ slightly in color.

A traffic sign that you will only see in Australia.

When driving through Australia, not only if you come from America or Europe will you be struck by driving on the other side of the road; Instead, traffic signs constantly point out kangaroo areas.

And it is that accidents caused by the sudden appearance of kangaroos crossing the road is extremely common.

Their weight can range from 0,5 kg to 90 kg, and the impact of these on vehicles can cause catastrophic damage to the vehicle, not to mention the number of dead animals on the roads.

Their habits are nocturnal, so driving in kangaroo areas at night requires more attention

While the red kangaroo can reach 2 meters in height with incredible musculature, other members of the family, such as wallabies, are extremely small.

Marsupials in Australia

Marsupials are among 3 broad groups that mammals are classified into, the other two being placental mammals and egg-laying mammals. 

The expression comes from the Greek word for pouch because certain members of the group have pouches that serve as a protective way of carrying their young. 

This group of mammals can also be called didelphia, based on the Greek for double uterus, and in fact that is a better description since the characteristic that is common to all members of the group of creatures is a course of double-channel sex organs. , the bag being present. as a specialized characteristic that is fully developed only among some of the primitive members of the group.

Marsupials are not as diverse as placental mammals, although egg layers are by far the smallest group. 

In terms of marsupialsYou will only marginally find more than 300 species present, of which about two-thirds are indigenous to Australia and some of the neighboring islands, such as New Guinea, and about a hundred indigenous to America, almost all of them in South America, one a dozen or so in Central America and one in North America. 

Marsupials had once been assumed to be primitive precursors to placental creatures, but the fossil record suggests that this is not the case, the two groups appear to have grown up at roughly the same time, i.e.

At the end of the Mesozoic era, suggesting that the separation between the teams took place substantially earlier. The first known marsupial, Sinodelphys szalayi, lived in China about 125 million years ago and it seems that it was out of here that the marsupials dispersed all over the world, however their journey to the areas they dominate today was very long.

During that time, China, Europe, and North America were thought to be linked together on a giant continent, and marsupials appear to have traversed Europe and into North America. A few million years later, those two great land masses had begun to fragment and the result was that South America, with Antarctica and Australia still together, had separated from Africa and the westward drift had collided and adhered. to North America that had detached from the Eurasian landmass.

In those times, the marsupials continued their journey and entered South America. About 50 million years ago, the marsupials had crossed into Antarctica, which was still attached to South America until only about 35 million years ago. Not long after these creatures entered Antarctica, Australia, which was still attached to Antarctica, broke away and began floating toward its current destination with a full load of marsupials. The breakdown of Australia and the remoteness of the southernmost parts of South America helped ensure the survival of the marsupials, while elsewhere, they became extinct in the face of competition within the food chain.
