Physical Description

Morphology

Physical Description

Short-snouted elephant shrews have the long, narrow snout, characteristic of all members of the family Macroscelididae, however the snout is shorter and it tapers slightly (Nowak, 1991). Average body length is 21 cm and tail length is approximately the same. Short-snouted elephant shrews vary in color depending on geographic location. They range from reddish-yellow to yellowish-brown or grey. All short-snouted elephant shrews have a faint white ring around the eyes. Short-snouted elephant shrews have soft fur and lack hair on the soles of their hind feet (Smithers, 1983).

Range mass: 40 to 60 g.

Average basal metabolic rate: 0.244 W.

Habitat

Short-snouted elephant shrews are found in arid and semi-arid environments. They prefer wooded bushlands and densely covered areas such as dense grasslands and scrub (Smithers, 1983).

Trophic Strategy

Food Habits

The short-snouted elephant shrew is primarily insectivorous, eating ants and termites (Smithers, 1983). They are, however, opportunistic feeders and eat small amounts of green plant material, fruits, and seeds (Leirs et al., 1995).

Reproduction

Reproduction

The gestation period is between 57 and 65 days. Young weigh approximately 10g at birth and reach adult size by 50 days (Nowak, 1991). On average, two young are produced per litter and are precocial, which means they are fully haired and are born with their eyes open (Smithers, 1983). Short-snouted elephant shrews are monogamous. Reproduction occurs throughout the year although conceptions decrease during cool periods. Females are able to produce between 5 and 6 litters a year, resulting in an average of 8 young per year (Neal, 1995).

Average number of offspring: 1.8.

Justification
The species is listed as Least Concern. Although this species is not abundant, it is widespread in suitable habitats over an immense area of Africa. Because it occupies habitats that are arid that will not support many types of human development there is no known major threats to this species or its habitats. Although there are no specific data available on population trends, there is no reason to believe that numbers are increasing or decreasing significantly due to any factors other than natural variation in environmental conditions in the relatively arid habitats that this species occupies. It is possible that desertification and bush encroachment due to various anthropogenic factors might impact this species, but without specific data this is speculation.
