The Somali elephant shrew or Somali sengi (Galegeeska revoilii) is a species of elephant shrew in the family Macroscelididae.

Habitat

Its natural habitat is arid and semiarid desert with rocky substrates and sparse shrubs. In some parts of Somalia, the Somali sengi and rufous sengi (G. rufescens) may be locally sympatric. It is found in the northern Horn of Africa; it was formerly thought to be exclusively endemic to Somalia, but a 2020 sighting also indicates they are found in Djibouti and potentially Ethiopia.

Classification

It was formerly classified in the genus Elephantulus , but a 2020 study found it to be the sister taxon of the clade containing the genera Petrodromus and Petrosaltator ; and the genus Galegeeska was coined for it. [3]

Disappearance and rediscovery

The Somali sengi was among the 25 "most wanted lost" species that were the focus of Global Wildlife Conservation's “Search for Lost Species” initiative. [4] On 18 August 2020, 50 years after it was last seen and recorded, it was announced that a population had been found in Djibouti, the first documented since 1968. [5] [6] [7]

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 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", a term derived from the Bantu languages of Africa, and in 1998, they were classified into the new clade Afrotheria.

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 28 cm (11 in) in length and 450–700 g (16–25 oz) in weight.

<span class="mw-page-title-main">Cape elephant shrew</span> Species of mammal

The Cape elephant shrew, also known as the Cape rock elephant-shrew or Cape rock sengi, is a species of elephant shrew in the family Macroscelididae. It is endemic to South Africa, although it is a relatively common animal. Its natural habitat is rocky areas. Elephant shrews are not closely related to true shrews, nor to rodents such as mice. E. edwardii has been observed to be a non-flying mammal pollinator of the pagoda lily. Elephant shrews are floral pollinators due to their largely insectivorous diet. Elephant-shrews are pollinators of Hyobanche atropurpurea. It uses its long slender tongue to feed on the pagoda lily's nectar while getting the lily's pollen on its long nose. E. edwardii is also a pollinator of Protea sulphurea.

<i>Rhynchocyon</i> Genus of mammals

Rhynchocyon is a genus of elephant shrew 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 Africa's coastal forests, Rift Valley highlands, and the 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:
