Potoroidae is a family of marsupials, small Australian animals known as bettongs, potoroos, and rat-kangaroos. They are similar in appearance to potoroos and bettongs, but are not as closely related. The boodie belongs to the family Potoroidae, which includes the rat-kangaroos, potoroos, and other bettongs. The park supports good populations of swamp wallabies, greater gliders, and potoroos. Kangaroos, wallabies and allies, bettongs, potoroos and rat kangaroos are all members of this suborder. This animal can be differentiated from other potoroos by its long back feet. Some lesser-known marsupials are the dunnarts, potoroos, cuscuses and the extinct thylacine. Since that time, an additional four potoroos have been sent to establish a breeding colony.
