Rhynchocyon
''Rhynchocyon'' is a genus of elephant shrew (or sengi) in the family Macroscelididae. Members of this genus are known colloquially as giant sengis. They are a ground-dwelling mammal, significantly larger than their relatives in the order Macroscelidea that live primarily in dense forests across eastern Africa. Habitats range from eastern Coastal forests of eastern Africa, Africa's coastal forests, East African Rift, Rift Valley highlands, and the Congo Basin, Congo basin. The species is widely threatened, with two of four assessed by the International Union for Conservation of Nature's Red List of Threatened Species. Habitat fragmentation from the growth of human settlements and activities are the primary threats to their populations. The genus contains the following five species and several subspecies: *Golden-rumped sengi, ''Rhynchocyon chrysopygus'' **''Rhynchocyon chrysopygus mandelai'' *Chequered sengi, ''Rhynchocyon cirnei'' **''Rhynchocyon cirnei shirensis'' **''Rhynchocyon ...

Elephant Shrew
Elephant shrews, also called jumping shrews or sengis, are small insectivore, insectivorous mammals native to Africa, belonging to the family Macroscelididae, in the order (biology), order Macroscelidea. Their traditional common English name "elephant shrew" comes from a perceived resemblance between their long noses and the trunk of an elephant, and their superficial similarity with shrews (family Soricidae) in the order Eulipotyphla. However, Phylogenetics, phylogenetic analysis has revealed that elephant shrews are not properly classified with true shrews, but are in fact more closely related to elephants than to shrews. In 1997, the biologist Jonathan Kingdon proposed that they instead be called "sengis" (singular ''sengi''), a term derived from the Bantu languages of Africa, and in 1998, they were classified into the new clade Afrotheria. They are widely distributed across the southern part of Africa, and although common nowhere, can be found in almost any type of habitat, ...

Rhynchocyon Petersi
The black and rufous sengi (''Rhynchocyon petersi''), the black and rufous elephant shrew, or the Zanj elephant shrew is one of the 17 species of elephant shrew found only in Africa. It is native to the lowland Montane ecosystems, montane and dense forests of Kenya and Tanzania. Like other members of the genus ''Rhynchocyon'', it is a relatively large species, with adults averaging about in length and in weight. Distribution and habitat 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 ...

Golden-rumped Sengi
The golden-rumped sengi (''Rhynchocyon chrysopygus'') is a small African mammal. It is the largest species of the elephant shrew family along with its close relative the grey-faced sengi. It is classified as endangered. Taxonomy and description The golden-rumped sengi is found in the northern coastal areas in and around Arabuko Sokoke National Park Mombasa in Kenya. Its name derives from the conspicuous golden fur on its hindquarters, distinctive golden coloration on its rump, and grizzled gold forehead contrasting with its dark reddish-brown color. The golden-rumped sengi has long muscular rear legs and shorter, less developed forelegs. Like other elephant shrews, this species has a long and flexible snout, which is where its genus gets its name. Its tail is largely black except for the last third, which is white with a black tip. On juveniles, the fur shows vestigial traces of a checkerboard pattern seen on giant sengis like the checkered elephant shrew. Reproduction The ...

Rhynchocyon Udzungwensis
The grey-faced sengi (''Rhynchocyon udzungwensis'') is a species of elephant shrew that is endemic to the Udzungwa Mountains of south-central Tanzania. The discovery of the species was announced in January 2008; only 15 species of elephant shrew were known until then, and the last discovery was made more than 120 years ago. As the name implies, the species is characterised by a distinctive grey face and a black rump, as well as being larger than the other species of elephant shrews. Description The fur of this sengi is sparse and glossy with a gray facial coloration and bright red pelage. A wide maroon stripe is noted along the back of the animal, as well as jet-black hindquarters with a light brown belly and tail. In comparison to the other sengis, the grey-faced sengi is larger in proportion and the upper tooth row is longer. The mean length of this species is , while the mean weight is . At , this species is about 25% larger than any other known sengi. Taxonomy The grey ...
