How do they reproduce?

These marsupial animals mate all year round with the peak being in the summer season. Females might form blood relationships with relatives. Females have a higher probability of reproduction if they live with female relatives. Eastern grey kangaroos believe in polygamy. Males get into fights with other males with the alpha male mating with the available females most probably. The female eastern kangaroo will give birth to one joey only. Their young, known as a joey, is born after a gestation phase that lasts for 36 days. The female is pregnant all the time, with the exception of the day of joey's birth. She is like a super kangaroo as she has the power to freeze the growth of her embryo (baby in her womb), till the time her joey in the pouch is comfortable enough to leave the pouch occasionally, which happens usually after 9-11 months after birth. This superpower of the mother kangaroo is known as embryonic diapause. It is astonishing that the female can have one baby in diapause and another in her pouch existing at the same time. She can employ this power when there is a lack of food or if there is a drought. The joey, in its early stages, makes very cute small hops circling his mother. At the age of 18 months, it is completely weaned (accustomed to food other than the mother's milk) and leaves the mother's pouch forever. Females have another superpower, producing different types of milk! The mother can produce milk as per the needs of her joey. She can make two types of milk, one for the newborn joey and the other for the older one. Joeys depend on their mother for approximately 550 days. The female joey matures at the age of 20-22 months, whereas the male joey mature at the age of 43 months.

What is their conservation status?

The number of this species is stable and thus, it is classified under the Least Concern category by the IUCN's Red List.
