The Black-flanked Rock Wallaby (*Petrogale lateralis*) is a small marsupial native to Australia. It is characterized by its dark fur on the back and distinctive black flanks, which help it blend into rocky environments. These wallabies are primarily found in the arid regions of Western Australia and South Australia, where they inhabit rocky outcrops and cliffs. These wallabies are herbivorous, feeding mainly on grasses, leaves, and fruits. They are known for their agility and ability to navigate steep terrains, which helps them escape predators. The Black-flanked Rock Wallaby is considered vulnerable due to habitat loss and predation by introduced species like foxes and cats. Conservation efforts are in place to protect their populations.
