Elephantulus rozeti
North African elephant-shrew
(Also: North African sengi)

Elephantulus rozeti is the only elephant-shrew, or sengi, (Macroscelidea) species that resides north of the Sahara. North African elephant-shrews occur in two disjunct populations: the first in Algeria, Morocco, Tunisia and the second in Libya. (Grzimek, 2003)

North African elephant-shrews occur in semi-arid savanna, bushland, shrubland, and woodland. (Grzimek, 2003)

North African elephant-shrews are roughly rodent-like in appearance, with a small body, large ears, and long tails. They weigh about 50g (very light compare to other genera in the same order). The head/body length is from 11 to 12.5 cm. The tail length is from 13 to 16 cm. The average body temperature is 33.6ºC. The fur on the dorsal side varies from yellowish brown to pale sandy-pink, and the fur on the ventral side is white. (Grzimek, 1990; Rathbun, 2005)

Elephant-shrews have long flexible snouts (probosci) that give them their names. The snout can be moved in a circular fashion. When they forage, they poke their snout into crevices or leaf litter, sniffing for food. The nostrils are located at the anterior end of the snout. Long sensory whiskers (vibrissae) arise from the base of the snout. (Grzimek, 2003)

The hindlimbs, which superficially resemble those of small antelopes, are longer than the forelimbs. This unique characteristic is probably an adaptation for cursorial and ricochetal locomotion. The tibia and fibula are long and fused. The metatarsals are lengthened, and the ulna and radius are also long, thus lengthening the stride and contributing to high-speed running and jumping. (Grzimek, 2003)

Members of this species have well-developed glands under the tail, which they use for marking territory. (Grzimek, 1990)

Information on the lifespan of E. rozeti is not available. The average lifespan of Elephantulus is 1 to 1.5 years in the wild and 3-4 years in captivity. The longest known lifespan of a E. rozeti was about 7 years, though the age of the animal was not scientifically determined. (Awaad and Weinstein, 2001)

Elephantulus rozeti are solitary animals. They form monogamous pairs to defend their territories. Usually, males fight off male rivals and females fight off female intruders. They scent-mark their territories with secretion from body glands. Foot-drumming and tail-slapping are classical behaviors of this species when it is in stressful situations. Elephantulus rozeti and other soft-furred macroscelids are also known for constructing complicated trail systems. (Grzimek, 2003; Rathbun, 2005; Schlitter, Wilson, and Reeder, 2005)

Specific behaviors of E. rozeti in the wild are not well-documented. However, some inferences from other members of Elephantulus might be made. Most of daily activity of Elephantulus rufescens involves "trail cleaning.” Trails are escape routes, which are constructed and maintained by removing leaves and loose debris with laterally directed forefoot sweeps. Except for foraging, activities are confined to these trails. (Schlitter, Wilson, and Reeder, 2005)

Elephant-shrews are seemingly alert at all times. Some species do not sleep with their eyes shut though they may close the eyes for 2 to 3 minutes. Usually, when they rest, they put their feet under the body, probably to facilitate rapid escape. Rest spots, established at various points along trails, are used for a short period and then abandoned. They do not use burrows, tree holes, nests or other secure retreats. (Schlitter, Wilson, and Reeder, 2005)

Low temperatures (below 25oC) or lack of food may cause members of this species to enter daily torpor, and their body temperatures may drop to as low as 5oC. Curiously, unlike most small mammals that use torpor to survive adverse conditions, they do not roll into a ball and reduce their surface areas when they enter torpor. Rather, they crouch with their snouts resting on the ground, and their eyes remain slightly open. No species of Elephantulus is known to build or use insulated nests either in captivity or in the wild. (Lovegrove, Raman, and Perrin, 2001)

Home Range

Information on home range in this species is not available.

Elephantulus rozeti use their long snouts to search for food under leaves or rocks, probably relying on their senses of touch and smell. They use chemical secreted from tail glands to mark territories. Females of the species scent-mark with their vagina when they circle around their potential mates. (Grzimek, 1990; Lumpkin and Koontz, 1986)

Elephant-shrews primarily eat insects. The specific diet for E. rozeti is unknown, but other Elephantulus species eat termites and ants, as well as shoots, berries, and roots. In captivity they accept various foods, including fruits and vegetables. (Awaad and Weinstein, 2001)

North African elephant-shrews can run and jump quickly to escape from predators. They may also freeze when they detect a threat. In this case, they may simply sit still and slap their elongated tail against the leaf litter. The color of their fur often remarkably resembles that of the soil (some shade of yellowish brown), which helps them to be camouflaged. Elephant-shrews are preyed on by large snakes, birds of prey, and medium-sized carnivorous mammals, such as foxes (Vulpes) and mustelids (Mustelidae). (Grzimek, 2003; Senior Scribe Publications, 2006)

This species is insectivorous and may play a role in regulating the populations of some insect species.

There are no negative effects of Elephantulus rozeti on humans.

With their mainly insectivorous diets, North African elephant-shrews are significant natural checks on the abundance of insects that might otherwise negatively affect human health and agriculture. (Grzimek, 2003)

North African elephant-shrews are not currently considered endangered. ("African Insectivora and Elephant-Shrews. An Action Plan for their Conservation", 1990)
