Psammobates
''Psammobates'' is a genus of tortoise erected by Leopold Fitzinger in 1835. This genus contains three species, all of which are indigenous to southern Africa.JCVI.org (Retrieved February 24, 2010.) The name means "sand-loving", and these tortoises typically inhabit the arid and semi-arid areas of southern Africa. Their diets and adaptations for this environment mean that these species do not generally survive outside their habitats and soon die when kept in captivity. All three species suffer from illegal collecting and , b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Psammobates Geometricus
The geometric tortoise (''Psammobates geometricus'') is a critically endangered species of tortoise and one of three members of the genus ''Psammobates''. It is found in a very small section in the South-Western Cape of South Africa. Identification It has a very strong, black and yellow patterned carapace, used for defence against predators. The patterns are arranged in ray-like markings and help the tortoise blend in with its environment. From a birds eye view the shell has geometrical symbols on it thus giving it its name. This tortoise is very small, and a full grown tortoise can only reach about 5 to 6 inches in diameter. The tortoise is one of the rarest species of tortoise of earth, only about 2,000 to 3,000 are alive today. However, because of its cryptic coloration and lack of activity, it makes it hard to create an accurate estimate of the population size. While it shares much of its superficial outer appearance with its relatives in the genus ''Psammobates'', i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Psammobates Oculifer
The serrated tortoise (''Psammobates oculifer'') german: Kalahari-Strahlenschildkröte is a species of tortoise that occurs in the Kalahari desert regions of southern Africa. Also known as the Kalahari tent tortoise, it is one of three members of the genus, ''Psammobates''. Name The common name internationally, serrated tortoise, stems from the characteristic, ray-like shell pattern and is shared by another tortoise species, ''Kinixys erosa''. In southern Africa it is known by the unambiguous name of Kalahari tent tortoise, after its Kalahari habitat. Distribution The serrated tortoise is found in Southern Africa. Here it favours arid savanna and scrub desert vegetation types (e.g. Kalahari thornveld, bushveld and arid grassland). This area lies within the border regions of Botswana, Namibia, and the Republic of South Africa from extreme W Transvaal and the W Orange Free State northwestward across most of Botswana and central and eastern Namibia. In this range, which roughly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tortoise
Tortoises () are reptiles of the family Testudinidae of the order Testudines (Latin: ''tortoise''). Like other turtles, tortoises have a turtle shell, shell to protect from predation and other threats. The shell in tortoises is generally hard, and like other members of the suborder Cryptodira, they retract their necks and heads directly backward into the shell to protect them. Tortoises can vary in size with some species, such as the Galápagos tortoise, Galápagos giant tortoise, growing to more than in length, whereas others like the Chersobius signatus, Speckled cape tortoise have shells that measure only long. Several lineages of tortoises Giant tortoise, have independently evolved very large body sizes in excess of 100 kg, including the Galápagos tortoise, Galapagos giant tortoise and the Aldabra giant tortoise. They are usually Diurnality, diurnal animals with tendencies to be crepuscular depending on the ambient temperatures. They are generally reclusive animals. ...

Turtle Genera
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plates th ...

Leopold Fitzinger
Leopold Joseph Franz Johann Fitzinger (13 April 1802 – 20 September 1884) was an Austrian zoologist. Fitzinger was born in Vienna and studied botany at the University of Vienna under Nikolaus Joseph von Jacquin. He worked at the Vienna Naturhistorisches Museum between 1817, when he joined as a volunteer assistant, and 1821, when he left to become secretary to the provincial legislature of Lower Austria; after a hiatus he was appointed assistant curator in 1844 and remained at the Naturhistorisches Museum until 1861. Later he became director of the zoos of Munich and Budapest. In 1826 he published ''Neue Classification der Reptilien'', based partly on the work of his friends Friedrich Wilhelm Hemprich and Heinrich Boie. In 1843 he published ''Systema Reptilium'', covering geckos, chameleons and iguanas. Fitzinger is commemorated in the scientific names of five reptiles: '' Algyroides fitzingeri'', '' Leptotyphlops fitzingeri'', '' Liolaemus fitzingerii'', ''Micrurus tener fitzi ...

Indigenous (ecology)
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. Every wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. The notion of nativity is often a blurred concept, as it is a function of both time and political boundaries. Over long periods of time, local conditions and migratory patterns are constantly changing as tectonic plates move, join, and split. Natural climate change (which is much slower than human-caused climate change) changes sea level, ice cover, temperature, and r ...

Southern Africa
Southern Africa is the southernmost subregion of the African continent, south of the Congo and Tanzania. The physical location is the large part of Africa to the south of the extensive Congo River basin. Southern Africa is home to a number of river systems; the Zambezi River being the most prominent. The Zambezi flows from the northwest corner of Zambia and western Angola to the Indian Ocean on the coast of Mozambique. Along the way, the Zambezi River flows over the mighty Victoria Falls on the border between Zambia and Zimbabwe. Victoria Falls is one of the largest waterfalls in the world and a major tourist attraction for the region. Southern Africa includes both subtropical and temperate climates, with the Tropic of Capricorn running through the middle of the region, dividing it into its subtropical and temperate halves. Countries commonly included in Southern Africa include Angola, Botswana, the Comoros, Eswatini, Lesotho, Madagascar, Malawi, Mauritius, Mozambique, Namib ...

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 ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...
