Surprising things about the kangaroo that few people know

Kangaroo, also known as Kang-gu-ru or Kangaroo, is a group of marsupial mammals of the Macropodidae. The word kangaroo is often used to refer to some of the largest species in this family such as the red Kangaroo, the Kangaroo Antilopin and the gray Kangaroo. Kangaroo also has many smaller species.

Kangaroo is one of the most famous marsupial family. They live in Australia's vast flat savannas. They also occur in open areas of New Guinea, Tasmania and New Zealand. On other continents, they can only be found in zoos. Kangaroo is the symbol of Australia.

The Australian desert is very hot, but Kangaroo can live there for a long time. When it's too hot, they lick their front legs (with little hair). When saliva evaporates, it will cool the blood below the skin and then the whole body.

Males of some species in the Kangaroo group have the ability to grow continuously throughout their lives. This is a very special ability in the animal world called infinite growth.

Children have up to 3 vaginas

This strange truth will surprise you. The female Kangaroo has an interesting anatomy: they have three vaginas. Two of them are used to transport sperm into the uterus. The middle vaginal part is used to transport newborn embryos to this world before it climbs to the mother kangaroo's pocket.

When you watch a match between two males, it's easy to recognize that the higher jump is the dominant one over the other. (Like other marsupials, male kangaroos are quite odd when the testes are located on the penis rather than the bottom.)

Kangaroo can determine the sex of the offspring

One of the best facts about kangaroos is that a female can determine the gender of her child. While we are still not sure how they can do such extraordinary things. Mother Kangaroos often give birth to female kangaroos when they are young, and give birth to male kangaroos after they leave the herd.

The kangaroos are still breastfed

After an adult kangaroo and leaves the bag, he will still go back to drinking breast milk. Because when there's an extra baby in the bag, the mother kangaroos will have a more advanced milk production system - one of its nipples will produce high carbohydrate milk for mature kangaroos and nipples. Another will produce a high-fat milk for young kangaroos.

Do they have 5 legs?

Although it sounds like a joke, kangaroos actually have a fifth leg that is a strong tail behind it. With the main purpose of helping the body balance while dancing, sometimes the fifth leg is also used for walking. Even, it is also a great assistant to help kangaroo balance when launching kicks ahead.

Despite the strong legs, the kangaroo cannot back up. For this reason, Australia has put a kangaroo as a badge on the coat of arms of the army to show that they are always moving forward and heading towards progress.

In contrast to kangaroo's hind legs, kangaroo attacks are almost harmless. However, in some fights for children, sometimes they still use this pair of legs.

Especially in childbirth

We will start this list with one of the most interesting and astonishing facts. A Kangaroo may become pregnant and then may stop giving birth when it feels that it is not ready. The truth is, if they are not ready for childbirth, for example when they are busy caring for another baby, then the embryo will stop growing after a few days until they really want to give birth.

Kangaroo eat corpses to get nutrients?

Contrary to the countries in the Northern Hemisphere, Australia usually lasts from December to February. Some small native species can struggle to survive drought. However, kangaroos with larger sizes and overcrowded numbers can die in mass.

A number of wildlife lakes located far away from residential areas have dried up for the first time in history, according to Vicki-Lee Wilson, manager of Arkaroola Wildlife Sanctuary in South Australia . "There are several lakes that we think will always have water, but now they are also depleted for a year and a half. The remaining water is dirty and the quality is poor. This is very bad , " she said.

Kangaroos desperately seek food, says ecologist Katherine Moseby of the University of New South Wales. Kangaroo died massively in arid areas where she worked last summer.

"We see kangaroos going into public toilets and eating toilet paper. They even eat the stomachs of roadside dead children, trying to get some nutrition from their dead bodies. It's horrible and heartbreaking." when witnessing that scene, " said Katherine Moseby.

Origin name name kangaroo 

The kangaroo name is derived from the  "gang -oo-roo"  in the Guugu Yimidhirr language meaning gray kangaroo.

According to anecdote, Captain James Cook and natural researcher Sir Joseph Banks met a strange animal during his research in Australia. They asked the resident of the animal for the name of the animal and received Kangaroo's answer, which means  "I don't understand" . Captain Cook thought it was the animal's name. However, in 1898, ethnologist WE Roth confirmed, "gangurru"  in Guugu Yimithirr meaning kangaroo.
