Unique frog species declared vulnerable
The desert rain frog (Breviceps macrops) has been classified as vulnerable on the International Union for Conservation of Nature (IUCN) red list, signaling a threat of extinction. The species is native to a narrow coastal strip of south-west Africa, including parts of South Africa and Namibia.
Adaptations to desert life
Unlike typical frogs that thrive in moist environments, the desert rain frog has evolved to survive in arid sand dunes. It has a rotund body and stumpy legs used for digging rather than jumping. Its skin acts like blotting paper, absorbing moisture through a highly vascularized pink patch on its belly. The frog burrows backward into the sand, descending about 30 cm to reach damp layers, and can remain there for months living off soil oxygen.
Threats from mining and development
The IUCN warns that diamond mining and infrastructure projects, such as the Boegoebaai port and rail project, are expected to affect one-third of the frog's range in South Africa and two-thirds in Namibia over the next 20 years. Increased urbanization also poses a threat. Without conservation efforts, the population is expected to decline by 20% in the next decade.
Pet trade concerns
Social media videos featuring the frog's high-pitched squeak—a distress call made in response to predators—have gone viral, leading to a surge in online searches about obtaining the frog as a pet. Conservationists warn that the frog is difficult to keep in captivity and should remain in its natural habitat. Dr Jeanne Tarrant, executive director of Anura Africa, noted that the squeak is often elicited by poking or traumatizing the animal.
Unique breeding biology
The male frog secretes a glue on his chest and forearms to attach himself to the female during reproduction. The female then digs a chamber and deposits eggs, which the male fertilizes. She also lays unfertilized eggs that liquefy; tadpoles whip this liquid into a foam that traps oxygen. Louis du Preez, professor of zoology at North-West University, described the frog's breeding, biology, and physical features as unique among frogs.
Conservation efforts needed
Experts emphasize that preserving sand dunes is the best way to protect the species. The desert rain frog is found nowhere else on Earth, making its conservation critical.
