Rhynchocyon
''Rhynchocyon'' is a genus of elephant shrew (or sengi) in the family Macroscelididae. Members of this genus are known colloquially as the checkered elephant shrews or giant sengis. It contains the following five species: *Golden-rumped elephant shrew, ''Rhynchocyon chrysopygus'' *Checkered elephant shrew, ''Rhynchocyon cirnei'' *Black and rufous elephant shrew, ''Rhynchocyon petersi'' *Stuhlmann's elephant shrew, ''Rhynchocyon stuhlmanni'' *Grey-faced sengi, ''Rhynchocyon udzungwensis'' Ecology The giant sengis are endemic to Africa, and usually live in lowland Montane ecosystems, montane and dense forests, often "avoiding" edges of forest patches. They eat primarily insects such as beetles, termites, ants, and centipedes, using their proboscises to dig them from the soil and its tongue to lick them up. Their facial morphology limits their diets to tiny invertebrates, and unlike other members of Macroscelidea, do not supplement their diet with foods such as nuts or small fruits ...

Elephant Shrew
Elephant shrews, also called jumping shrews or sengis, are small insectivorous mammals native to Africa, belonging to the family Macroscelididae, in the 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, 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, from the Namib Desert to boulder-strewn ou ...

Black And Rufous Elephant Shrew
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. It is native to the lowland 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 declining; sufferi ...

Rhynchocyon Chrysopygus
The golden-rumped elephant shrew (''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 elephant shrew 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 elephant shrew 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 elephant shrews like the checkered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grey-faced Sengi
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhynchocyon Cirnei
The checkered elephant shrew or checkered sengi (''Rhynchocyon cirnei'') is a species of elephant shrew in the family Macroscelididae. Description Checked elephant shrews will grow to be around long, excluding their tail, making them one of the longest elephant shrews. Their average tail length is slightly over 25 centimeters, which is slightly shorter than their body length. They commonly weigh around half a kilogram (1.1 pounds), but will sometimes grow to be about . Their coat is usually a light to medium brown, but it can range from beige to dark brown. Their back contains alternating chestnut and lighter colors, creating a "checkered" pattern. Checkered elephant shrews also contain stripes on the sides of their body, which have a darker color than most of their body. Range and habitat It is found in Democratic Republic of the Congo, Malawi, Mozambique, Tanzania, Uganda, Zambia, and possibly Central African Republic.

Rhynchocyon Stuhlmanni
The Stuhlmann's elephant shrew (''Rhynchocyon stuhlmanni'') is a species of elephant shrew that lives in the forests and savannas of Africa. It was discovered in 1893 and declared a new species. In the 1960s, however, it was downgraded to a subspecies of checkered sengi (''Rhynchocyon cirnei''). In 2018, following genetic tests, scientists re-evaluated the mammal as a full species again. The elephant shrew is named after Franz Stuhlmann, a German zoologist, whose name is also found on a variety of other Central African species and subspecies, including Stuhlmann's golden mole (''Chrysochloris stuhlmanni''), Stuhlmann's double-collared sunbird (''Cinnyris stuhlmanni''), Stuhlmann's starling Stuhlmann's starling (''Poeoptera stuhlmanni'') is a species of starling in the family Sturnidae.
