Kangaroos are endemic to Australia. Over 34 million of these marsupials live in the country. About 11 million of them are eastern grey kangaroos. Their range is the eastern third of Australia. Although smaller than the red kangaroo, the great grey kangaroo is very large. A male averages 145 pounds and stands about 6.5 feet. The joey spends its first 190 days in the mother’s pouch and completely leaves the shelter after 235 days. These two were grazing in the wild at Euroka Clearing in the Blue Mountains.
