Along the windswept, diamond-rich coast of Port Nolloth in South Africa, the landscape is a shifting desert of pale, fine-grained sand dunes. For nearly nine decades, this hyper-arid strip of land held a secret buried beneath its undulating surface. Scientists feared that De Winton’s golden mole ( Cryptochloris wintoni ), a small, blind mammal with a shimmering, iridescent coat, had slipped quietly into extinction, last seen by researchers in 1937. The search for this elusive creature required a radical departure from traditional tracking methods, as the mole leaves no permanent tunnels in the dry, fluid-like sand. Instead, it "swims" through the subsurface, leaving only fleeting, wave-like ridges on the dune surface that are quickly erased by the Atlantic winds. In late 2023, a team of geneticists and conservationists successfully detected the mole's presence using environmental DNA (eDNA) extracted directl...

The windswept beaches of Port Nolloth, along South Africa’s rugged northwestern coast, hold secrets buried deep beneath shifting mountains of sand. For nearly nine decades, one of those secrets was De Winton’s golden mole ( Cryptochloris wintoni ), a small, iridescent mammal that literally swims through the subterranean desert. Last seen by scientists in 1937, the species was widely feared to be extinct, lost to the relentless encroachment of diamond mining and coastal development. The species had become a ghost, existing only as a handful of faded specimens in museum drawers. However, a pioneering scientific expedition has shattered this silence, bringing the elusive creature back from the brink of myth. Using cutting-edge environmental DNA (eDNA) technology and specialized tracking, researchers have officially...
