Description

These tiny mouse-like animals vary in colour from grey to brown, and sometimes may have a combination of the two colours. They have a long nose, big eyes and ears, and long, slender limbs. 

 

Habitat

Elephant shrews live in a variety of habitats throughout Africa, including semi-deserts, savannahs and coastal rainforests. They are absent from the Sahara region and western Africa deserts. Some species of elephant shrew live in burrows in the ground, while others nest under leaves on the forest floor. 

 

Feeding Habits

Elephant shrews are active during the day and use their long tongue to scoop up insects and bring them to their mouth, much as an elephant uses its trunk to scoop food. They have a long flexible nose that is useful in sniffing out insects. Shrews feed on ants and termites, and may also feed on roots, fruit and seeds.

 

Reproduction

There is no set mating season. Gestation lasts between 42 and 60 days. The young are born with fur and their eyes are open. They can follow their mother almost immediately after birth and are weaned within four weeks. Within another week, the youngsters become fully independent, although they may stay within their parents’ territory until they establish their own.  Some elephant shrews, such as golden-rumped elephant shrews, mate for life. 

 

Behaviour

When elephant shrews feel threatened, they slap their tail repeatedly on the forest ground. If they continue to feel threatened, they will  run and slap their hind legs on the ground, to help warn other shrews of the presence of a predator. Elephant shrews are extremely territorial and become irate when another shrew approaches them on their own territory. They usually walk on all four limbs, but when they want to move quickly in order to get away from danger, they jump using their powerful hind legs.

  

Conservation

In Kenya, elephant shrews are protected within the Gedi Historical Monument. Otherwise, the habitat of the elephant shrew is shrinking due to human encroachment. According to the IUCN, the following species are classified as Vulnerable: Elephantulus edwardii, Elephantulus rupestris, Macroscelides proboscideus and Rhynchocyon cirnei. Elephantulus revoili, Rhynchocyon chrysopygus and Rhynchocyon petersi are classified as Endangered. The remaining species of elephant shrew have no special status.
