A new mammal discovered in the remote desert of Western Africa resembles a long-nosed mouse in appearance but is more closely related genetically to elephants, a California scientist who helped identify the tiny creature said.

The new species of elephant shrew, given the scientific name Macroscelides micus, inhabits an ancient volcanic formation in Namibia and sports red fur that helps it blend in with the colour of its rocky surroundings, said John Dumbacher, one of a team of biologists behind the discovery.

Genetic testing of the creature – which weighs up to 28g and measures 19cm in length, including its tail – revealed its DNA to be more akin to much larger mammals.

The findings, published in the Journal of Mammalogy, floored scientists, who said the only visible link between an African elephant and the diminutive shrew is its trunk-like nose.

An elongated snout is a common feature of various shrew species, though shrews are not classified as rodents.
