Macropus robustus

The common wallaroo (Osphranter robustus), also known as the euro, hill wallaroo, or simply wallaroo, is a species of macropod (a family of marsupials that also includes kangaroos and wallabies). The word euro is particularly applied to one subspecies (O. r. erubescens).

The eastern wallaroo is mostly nocturnal and solitary, and is one of the more common macropods. It makes a loud hissing noise and some of the other subspecies are sexually dimorphic, like most wallaroos.
