Macroscelides
''Macroscelides'' is a genus of small shrew-like animals, the round-eared sengis (also called elephant shrews), found in western Namibia and in South Africa; they are members of the clade Afrotheria. There are three known species: * Namib round-eared sengi, ''Macroscelides flavicaudatus'' * Etendaka round-eared sengi, ''Macroscelides micus ''Macroscelides micus'' (common name Etendeka round-eared sengi or Etendeka round-eared elephant shrew) is a species of elephant shrew in the family Macroscelididae.

Macroscelides Micus
''Macroscelides micus'' (common name Etendeka round-eared sengi or Etendeka round-eared elephant shrew) is a species of elephant shrew in the family Macroscelididae. It is only found in gravel plains in the Etendeka formation of north-west Namibia. Measuring about long and weighing less than an ounce (28 grams), the species is the smallest in the elephant shrew family. Description ''Macroscelides micus'' is the smallest known elephant shrew. Its body shape resembles that of a long-nosed mouse. However, as a member of the superorder Afrotheria, it is actually more closely related to elephants and manatees than mice. It has pink skin and red fur which helps it camouflage itself against the volcanic rocks of its environment. It weighs less than one ounce (28 grams) and is long, including the tail, when fully grown. ''M. micus'' has long, thin legs relative to its body. ''M. micus'' does not burrow, instead sleeping in bushes. It uses its long nose to hunt for ground insects. Some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sengi
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 out ...

Macroscelides Proboscideus
The round-eared elephant shrew (''Macroscelides proboscideus'') or round-eared sengi (called the Karoo round-eared elephant shrew to distinguish it from its sister species; formerly misleadingly named the "short-eared elephant shrew"), is a species of elephant shrew (sengi) in the family Macroscelididae. It is found in Botswana, Namibia, and South Africa. Its natural habitats are subtropical or tropical dry shrubland, and grassland, and hot deserts. They eat insects, shoots, and roots. Their gestation period is 56 days. Elephant shrews are among only a handful of monogamous mammals, making them a model group for the study of monogamy. They have been studied for their mate guarding In biology, mating is the pairing of either opposite-sex or hermaphroditic organisms for the purposes of sexual reproduction. ''Fertilization'' is the fusion of two gametes. ''Copulation'' is the union of the sex organs of two sexually reproduc ... behavior. Mate guarding is considered a predomina ...

Macroscelides Flavicaudatus
''Macroscelides flavicaudatus'' (common name: Namib round-eared sengi or Namib round-eared elephant shrew) is a species of elephant shrew in the family Macroscelididae found in the central Namib desert and southern Namibia. Discovery and identification ''Macroscelides flavicaudatus'' was first described by Lundholm as ''Macroscelides proboscideus flavicaudatus'', a subspecies of '' M. proboscideus''. The type specimen had been collected by the Plague Research Laboratory of the South African Institute for Medical Research, "six miles from the mouth of the Omaruru River" in Namibia. It is distinguished by the lighter coloration of its fur. Nine other subspecies of ''M. proboscideus'' had previously been described; while Corbet and Hanks dismissed the variation between these as continuous Continuity or continuous may refer to: Mathematics * Continuity (mathematics), the opposing concept to discreteness; common examples include ** Continuous probability distribution or r ...

Andrew Smith (zoologist)
Sir Andrew Smith (3 December 1797 – 11 August 1872) was a British surgeon, explorer, ethnologist and zoologist. He is considered the father of zoology in South Africa having described many species across a wide range of groups in his major work, ''Illustrations of the Zoology of South Africa''. Smith was born in Hawick, Roxburghshire. He qualified in medicine at the University of Edinburgh obtaining an M.D. degree in 1819, having joined the Army Medical Services in 1816. South Africa 1820–1837 In 1820 he was ordered to the Cape Colony and was sent to Grahamstown to supervise the medical care of European soldiers and soldiers of the Cape Corps. He was appointed the Albany district surgeon in 1822 and started the first free dispensary for indigent patients in South Africa. He led a scientific expedition into the interior and was able to indulge in his interests of natural history and anthropology. On several occasions, he was sent by governors on confidential missions to vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Afrotheria
Afrotheria ( from Latin ''Afro-'' "of Africa" + ''theria'' "wild beast") is a clade of mammals, the living members of which belong to groups that are either currently living in Africa or of African origin: golden moles, elephant shrews (also known as sengis), tenrecs, aardvarks, hyraxes, elephants, sea cows, and several extinct clades. Most groups of afrotheres share little or no superficial resemblance, and their similarities have only become known in recent times because of genetics and molecular studies. Many afrothere groups are found mostly or exclusively in Africa, reflecting the fact that Africa was an island continent from the Cretaceous until the early Miocene around 20 million years ago, when Afro-Arabia collided with Eurasia. Because Africa was isolated by water, Laurasian groups of mammals such as insectivores, rodents, lagomorphs, carnivorans and ungulates could not reach Africa for much of the early to mid- Cenozoic. Instead, the niches occupied by thos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic units known as "taxa" (singular "taxon")." Taxonomy is different from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
