There are currently 16 species of rock wallaby. Physical description. Rock wallabies specialise in rugged terrain and have modified feet designed to grip rock with skin friction rather than dig into soil with large claws.
Although there are many different species of both wallabies and kangaroos that span a wide range of sizes, wallabies only tend to weigh between four pounds and 53 pounds (2 kg to 24 kg) and grow a mere 12 inches to 24 inches (30 cm to 104 cm) tall, not including their tails [source: Wallaby].
