Abstract:

We wish to draw your attention to a peer-reviewed article that we authored, recently published in Quaternary Research (Lockley et al., 2021), titled: "Pleistocene golden mole and 'sand-swimming' trace fossils from the Cape coast of South Africa". It presented the fossil evidence that our research team has found for the tracks and burrows of golden moles, and in particular of the genus Eremitalpa, which is exemplified by the 'Namib mole' or Grant's golden mole, Eremitalpa granti. In this letter, we briefly review this evidence and discuss its implications for Namibia. The Namib mole is one of the iconic Namibian desert-dwelling mammals, and has captured the world's attention. Eighteen of the world's 21 golden mole species occur in southern Africa. Eremitalpa is a monospecific genus, with two subspecies on the west coast, separated by the Orange River. Eremitalpa granti namibensis occurs in Namibia, south of the Kuiseb River, and E. granti granti occurs in South Africa, as far south as St. Helena Bay. Although totally blind, the Namib mole has developed a search pattern that is effective in encountering patches of high prey availability. It is the smallest of the golden moles, and has limbs and claws that are adapted for burrowing in loose sand in search mainly of termites. It is acutely sensitive to vibrations as a means of locating its prey. It hunts at night, travelling through the sand at a much shallower depth than any other golden mole, in a form of locomotion known as 'sand-swimming'.
