The term rock wallaby refers to a species of marsupial that inhabits rocky areas in Australia and nearby islands. Some synonyms for this animal include cliff wallaby, rock-hopping kangaroo, and rock-dwelling wallaby. These animals are mid-sized with short and powerful legs that allow them to scale steep cliff faces and ledges without difficulty. The fur of rock wallabies ranges from gray to brown and they have long tails that help them balance while jumping from rock to rock. They are herbivores that feed on leaves, flowers, and fruit. Rock wallabies are nocturnal, and they sleep during the day in caves or crevices.
