Kangaroos are a group of marsupial species in the family Macropodidae. They often concentrated in Central and Western Australia in their favorite habitats are deserts, grasslands and shrubland.
Their food is mainly fungi, plants, insects … Kangaroo is mainly active at night, but in cool weather, they can feed all day.
Every little thing about these animals is incredibly interesting, but one feature that sets them apart from the majority is that the reproductive and rearing processes are unlike anyone. They put their baby in a pocket in front of their stomach.
But why is that?
In order to explain this behavior, one must understand baby kangaroos
New born animals are usually only as small as… a black bean. It has even been reported that babies of kangaroos are incredibly small with the size of a grain of rice! Due to this extremely modest size, if the mother kangaroo also takes care of her baby the way other animals do, it will face countless difficulties.
Kangaroo babies when born are extremely small, just the size of beans
The size of the mother compared to the young is extremely large, they are quite clumsy, so feeding the baby is of course a disturbing challenge. If the baby accidentally falls out, the parent kangaroo will have to abandon it for a very understandable reason: they cannot pick it up and put it back in the bag.
In addition, the offspring are born before the body can fully develop, so they are extremely weak, and nearly unable to survive in the external environment. The only completed parts were the limbs.
That helps the kangaroo a lot because soon after they are born they will have to crawl into the mother’s bag, and spend the next months in this warm place.
Thanks to their instincts, although they do not have eyes, most can find their own way – only a few kangaroos have to ask for help from their mother.
Here, they cling to the nipples inside the bag and grow on milk. Their muscles are not strong enough to do anything – including breastfeeding. Therefore, the nipple of the mother kangaroo has a specialized muscle that takes over the task of pumping food automatically.
Babies will eat, sleep and excrete in this bag. The waste can be absorbed in the bag lining or removed by the mother kangaroo with her mouth.
On average, after 4 months, the young have a full body parts and a soft coat. Then they can poke their heads out of their pockets to see the world. But it takes 20 months (for the female) and 2 – 4 years (for the male) for the baby kangaroo to really be big enough to come out of the mother’s bag.
Even after being able to live independently, baby kangaroos sometimes come back to breastfeed
