The eastern grey kangaroo is a very common animal in Australia.

It is a marsupial, which is a type of mammal. This animal is the second largest and heaviest marsupial in Australia. It is also the second heaviest native land mammal there. These kangaroos live in the eastern third of the country. There are several million of them living in the wild. They like to stay in wet and fertile places. They often live in grasslands, woodlands, and even mountain forests.

These animals have a very special way of being parents. A mother kangaroo can use embryonic diapause to help her babies. This is a way to freeze the growth of a new embryo. She does this when there is a drought or little food. This helps her wait until the previous joey leaves the pouch. The mother can even make two different kinds of milk at once. One kind is for a newborn and one is for an older joey.

The young joeys stay with their mothers for about 550 days.

Scientists have studied these kangaroos for a long time. George Shaw first described them in the year 1790. He gave them the scientific name Macropus giganteus. This name means "gigantic large-foot." There has been some debate about different groups of these kangaroos. For example, Albert Sherbourne Le Souef named a Tasmanian group in 1923. Some experts thought they were different subspecies based on coat color. However, a study in 2003 found very little genetic difference between them.

Eastern grey kangaroos have many unique physical facts. An adult male can weigh around 90 kilograms. Females are usually smaller and weigh around 35 kilograms. They have a very powerful tail that can be over 1 meter long. The largest specimen ever examined by Lydekker was very huge. It weighed 135 kilograms and was 3.3 meters long.

You can recognize them by their soft grey or brownish-grey coats. They also have a lighter silver or cream belly. They do not have the black and white face markings that red kangaroos have.

Knowing about kangaroos helps us understand the Australian land. They are very adaptable and can live near big cities. In 2010, there were about 11.4 million eastern grey kangaroos in Australia. They eat many kinds of grasses and forbs. They often live in groups of about three individuals. These groups help them watch for predators. Some people even think about using kangaroo meat to replace beef. Their soft feet are better for the ground than hard hooves.
