Grant's golden mole (Eremitalpa granti; colloquially also: dune shark) is a golden mole species. It is the only member of the genus Eremitalpa.

Description

Like all other golden moles, the build of these animals is similar to the moles, though they are not closely related, and are adapted to a life of digging. The front extremities are remodelled to digging claws; in contrast to most other species of its family, they have three claws each. The tail is physically not visible, there are no auricles, the eyes are covered with fur, and the mouth is bearing a leather-like pad, which also serves for digging.

Grant's golden moles have long silky fur, which is coloured grey on cubs and sandy on older animals. With a length of 7.5 to 9 cm (3.0 to 3.5 in) and a weight of 15 to 25 g (0.53 to 0.88 oz) it is the smallest member of its species.

Geographical distribution and habitat

Grant's golden mole lives on the western coast of South Africa and in south western Namibia. [1] Its natural habitat is dry areas, mostly sandy deserts. [1]

Diet and social behaviour

In contrast to many other golden moles, Grant's golden mole rarely builds lasting tunnels. It "swims" through the sand just under or on the surface while searching for food. It is mainly a nocturnal animal, resting by day in small caves beneath sheltering plants. [1] It is a solitary animal, with stomping grounds averaging 4.6 ha. When foraging at night, the animal will alternate between moving over the surface sand, dipping its head into the substrate (detecting low frequency vibrations through the ground) [2] and "swimming" through the sand. [2]

Besides termites (which constitute the majority of its food) and other invertebrates, its diet consists of reptiles such as skinks.

Taxonomy

There are two subspecies: [3]

Conservation status

This species has been classified by the IUCN Red List as LC (Least Concern) globally. [1] However, the Endangered Wildlife Trust of South Africa regards the nominate subspecies as a Vulnerable species. [4]

<span class="mw-page-title-main">Golden mole</span> Monotypic family of mammals

Golden moles are small insectivorous burrowing mammals endemic to Sub-Saharan Africa. They comprise the family Chrysochloridae and as such they are taxonomically distinct from the true moles, family Talpidae, and other mole-like families, all of which, to various degrees, they resemble as a result of evolutionary convergence. There are 21 species. Some are relatively common, whereas others are rare and endangered.

The southern marsupial mole, also known as the itjaritjari or itjari-itjari, is a mole-like marsupial found in the western central deserts of Australia. It is extremely adapted to a burrowing way of life. It has large, shovel-like forepaws and silky fur, which helps it move easily. It also lacks complete eyes as it has little need for them. It feeds on earthworms and larvae.

The northern marsupial mole or kakarratul is a marsupial in the family Notoryctidae, an endemic animal of arid regions of Central Australia. It lives in the loose sand of dunes and river plains in the desert, spending nearly its entire life beneath ground. The facial features are reduced or absent; their small and strong bodies, weighing little more than 30 grams, are extremely specialised in moving through sand in search of prey. The species is elusive and it is one of the most poorly understood mammals of Australia.
