Wallaroo Wallaroo is any of three closely related species of moderately large macropod, intermediate in size between the kangaroos and the wallabies. The word "wallaroo" is from Dharug "walaru". In general, a large, slim-bodied macropod of the open plains is called a "kangaroo"; a small to medium-sized one, particularly if it is relatively thick-set, is a "wallaby": most wallaroos are only a little smaller than a kangaroo, fairly thickset, and are found in open country. All share a particular habit of stance: wrists raised, elbows tucked close into the body, and shoulders thrown back, and all have a large, black-skinned rhinarium.
