The Black-flanked Rock-wallaby is a small marsupial native to Australia, specifically found in rocky outcrops and cliffs in the western regions. It has a distinctive black stripe along its flanks, which gives it its name. This species is primarily nocturnal and feeds on grasses, leaves, and fruits. These wallabies are social animals, often seen in small groups. They are agile climbers, using their strong hind legs to navigate rocky terrains. The Black-flanked Rock-wallaby is currently classified as vulnerable due to habitat loss and predation by introduced species like cats and foxes. Conservation efforts are underway to protect their populations.
