The black and rufous elephant shrew, Rhynchocyon petersi the black and rufous sengi, or the Zanj elephant shrew is one of the 17 species of elephant shrew found only in Africa Like other members of the genus Rhynchocyon, it is a relatively large species, with adults averaging about 28 cm 11 in in length and 450-700 g 10-15 lb in weight It is native to the lowland montane and dense forests of Kenya and Tanzania It eats insects such as beetles, termites, and centipedes, using its proboscis to dig them from the soil and its tongue to lick them up It typically builds ground level nests for shelter requiring dry leaf litter often at the base of trees Like most elephant shrews, it lives in monogamous pairs, defending hectare-sized territories Distribution of Rhynchocyon petersi in Tanzania The species is typically limited to small, fragmented forest patches darker blue within the Eastern Arc Mountains blue
The forests of the Eastern Arc Mountains are critical habitats for R petersi The Chome Forest Reserve in Tanzania is an isolated, and largely undisturbed, habitat for the shrews Populations densities in the Chome area are significantly lower than the surrounding areas, home to approximately 2700 R petersi, and is thought to be the result of restricted migration and illegal human activity It was once listed by the IUCN Red List as vulnerable, but has since been changed to a status of least concern However, its numbers are reportedly declining; suffering from severe forest fragmentation and degradation from human expansion
Several zoos have begun breeding this elephant shrew, including the Philadelphia Zoo in the United States Two black and rufous elephant shrew males were born on February 4, 2007, at the National Zoo in Washington, DC
