Cryptomys Hottentotus
The common mole-rat, African mole-rat, or Hottentot mole-rat, (''Cryptomys hottentotus'') is a burrowing rodent found in Southern Africa, in particular in the Western Cape province of South Africa. It also occurs in Eswatini, Lesotho, Malawi, Mozambique, Tanzania, Zambia, and Zimbabwe. It is a species in the subfamily Bathyerginae. Taxonomy René Primevère Lesson was the first to describe the common mole-rat in 1826, based on an animal captured near Paarl, and called it ''Bathyergus hottentotus''. The following year, the Dutch zoologist Anton Brants described a specimen from the eastern part of the Cape Colony which he named ''Bathyergus caecutiens''. In 1828, Andrew Smith described ''Bathyergus ludwigii''. Around 1900 these little mole rats were no longer considered to fit into the genus ''Bathyergus'', and various forms were described in the genus ''Georychus'', namely ''G. exenticus'' in 1899 by Édouard Louis Trouessart, ''G. jorisseni'' in 1909 by Henry Lyster Jameson ...

Blesmol
The blesmols, also known as mole-rats, or African mole-rats, are burrowing rodents of the family Bathyergidae. They represent a distinct evolution of a subterranean life among rodents much like the pocket gophers of North America, the tuco-tucos in South America, or the Spalacidae from Eurasia. Distribution Modern blesmols are found strictly in sub-Saharan Africa. Fossil forms are also restricted almost exclusively to Africa, although a few specimens of the Pleistocene species ''Cryptomys asiaticus'' have been found in Israel. Nowak (1999) also reports that †''Gypsorhychus'' has been found in fossil deposits of Mongolia. Anatomy Blesmols are somewhat mole-like animals with cylindrical bodies and short limbs. They range from in length, and from in weight, depending on the species. Blesmols, like many other fossorial mammals, have greatly reduced eyes and ear pinnae, a relatively short tail, loose skin, and (aside from the hairless naked mole rat) velvety fur. Blesmols ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
