The monjon (Petrogale burbidgei) is the smallest species of rock-wallaby, belonging to the family Macropodidae, and is endemic to the Kimberley region of Western Australia.
Adult monjons stand only about 30–35 cm tall, with a body weight of around 1–1.5 kg, making them the tiniest members of their group. They have soft brown-gray fur, a paler underbelly, and a long, bushy tail used for balance among rocky outcrops. Adapted to rugged sandstone habitats, they are shy and elusive, often retreating into crevices when disturbed. Monjons are herbivorous, feeding on grasses, leaves, and other vegetation. They are mostly nocturnal, emerging at dusk to forage. Due to their restricted range and specific habitat needs, they are vulnerable to threats such as altered fire regimes, predation by feral cats, and habitat disturbance, though populations remain stable in protected areas.
