Ghost frogs get their name as one of the six species found in Skeleton Gorge (on Table Mountain), South Africa. The underside of the body, including the jaw, has small hooks, which help the frogs climb over wet rocks near their habitats. The frogs measure in length. It is in the same size range as Hewitt's ghost frog, but is smaller than Purcell's ghost frog. The top side of its body is brown with yellow spots, and the underside is white. The limbs are plain-colored, and flesh-colored underneath. Their tadpoles take up to two years to develop fully. The call of the royal ghost frog is a harsh, creaking sound, given at around one call per second.
