About Heleophryne regis Hewitt, 1910
Heleophryne regis, commonly known as the royal ghost frog, gets its common name because one of the six known ghost frog species is found in Skeleton Gorge on Table Mountain, South Africa. This frog species measures 35โ45 mm (1.4โ1.8 in) in length. It falls in the same size range as Hewitt's ghost frog, but is smaller than Purcell's ghost frog. Small hooks cover the underside of its body, including the jaw, that help this frog climb across wet rocks near its habitat. The dorsal (top) side of its body is brown with yellow spots, while its ventral (underside) is white. Its limbs are solid in color, and are flesh-colored on their undersides. Tadpoles of this species take up to two years to fully develop. The call of the royal ghost frog is a harsh, creaking sound, produced at a rate of roughly one call per second. All ghost frog species are endemic to the southern tip of Africa. The natural habitat of Heleophryne regis is fynbos heathland in the Western and Eastern provinces of South Africa, specifically cool mountain streams at altitudes between 230 and 790 meters. This species requires clean, fast-moving water to survive, so it is threatened by habitat loss. The International Union for Conservation of Nature currently classifies this species as Least Concern: despite occupying an area smaller than 20,000 square kilometres (7,700 sq mi), its habitat is not currently threatened, and the species is presumed to have a large population. One recorded threat to its habitat is siltation of freshwater streams.
