Kangaroo weights can vary significantly depending on the species. Adult male red kangaroos, which are the largest, typically weigh between 50 to 90 kilograms (110 to 200 pounds), while females usually range from 25 to 35 kilograms (55 to 77 pounds). Other species, like the eastern gray kangaroo, have males weighing around 66 kilograms (145 pounds) and females about 34 kilograms (75 pounds).
Factors such as diet, habitat, and age also influence their weight. Kangaroos are herbivores, feeding mostly on grasses and is reflected in their overall health and size. Juvenile kangaroos, called joeys, are much lighter at birth and gradually gain weight as they grow, which can take anywhere from six to twelve months before they fully leave the pouch.
This weight range can help researchers and wildlife enthusiasts understand the health and population dynamics of kangaroos, which are iconic to Australia and play a significant role in their ecosystems.
