DID YOU KNOW?
By Any Other Name: Kangaroos have some funny names. Males are called boomers, bucks or old men. Females are known as flyers, jills or does. And young kangaroos are called joeys.
Four Plus More: There are only four true kangaroo species: the red, eastern gray, western gray and antilopine kangaroos. There are roughly 50 other closely related species, including wallabies, tree-kangaroos and pademelons.
Few Predators: Most of the kangaroo's natural predators have gone extinct, including the thylacine and marsupial lion. Today, the dingo — introduced to Australia some 5,000 years ago — is one of the only predators they have to worry about.
