Pipidae
The Pipidae are a family (biology), family of primitive, tongueless frogs. There are 41 species in the family, found in tropical South America (genus ''Pipa'') and sub-Saharan Africa (the three other genera). Description Pipid frogs are highly aquatic and have numerous morphological modifications befitting their habitat. For example, the feet are completely webbed, the body is flattened, and a lateral line system is present in adults. In addition, pipids possess highly modified ears for producing and receiving sound under water. They lack a tongue or vocal cords, instead having bony rods in the larynx that help produce sound. They range from in body length. Taxonomy Morphological data suggest that ''Xenopus'' is the sister-group of all other pipids, whereas molecular data consistently suggest that ''Pipa (frog), Pipa'' is the sister-group of other pipids. Family Pipidae * ''Hymenochirus'' - dwarf clawed frogs (4 species) * ''Pipa (frog), Pipa'' - Surinam toads (7 species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Itombwe Massif
The Itombwe Mountains (or Itombwe Massif, Plateau) are a range of mountains in the South Kivu province of the Democratic Republic of the Congo (DRC). They run along the west shore of the northern part of Lake Tanganyika. They contain a vast area of contiguous montane forest and are home to a rich diversity of wildlife. Geography The Itombwe mountains are a section of the Albertine Rift Mountains, which border the western branch of the East African Rift. These mountains extend from the Rwenzori Mountains in the north to the Marungu highlands in the south. They are made up of uplifted Pre-Cambrian basement rocks overlaid in places by recent volcanic activity. Both of these are caused by the forces that created the Great Rift Valley, where tectonic stresses are causing parts of East Africa to separate from the continent. The highest peak of the Albertine Rift Mountains is further north in the Rwenzori Mountains, at . The highest peak in the Itombwe range is Mount Mohi, at . Severa ...

Democratic Republic Of The Congo
The Democratic Republic of the Congo (DRC), also known as the DR Congo, Congo-Kinshasa, or simply the Congo (the last ambiguously also referring to the neighbouring Republic of the Congo), is a country in Central Africa. By land area, it is the List of African countries by area, second-largest country in Africa and the List of countries and dependencies by area, 11th-largest in the world. With a population of around 112 million, the DR Congo is the most populous nominally List of countries and territories where French is an official language, Francophone country in the world. Belgian French, French is the official and most widely spoken language, though there are Languages of the Democratic Republic of the Congo, over 200 indigenous languages. The national capital and largest city is Kinshasa, which is also the economic center. The country is bordered by the Republic of the Congo, the Cabinda Province, Cabinda exclave of Angola, and the South Atlantic Ocean to the west; the Cen ...

Xenopus
''Xenopus'' () (Gk., ξενος, ''xenos'' = strange, πους, ''pous'' = foot, commonly known as the clawed frog) is a genus of highly aquatic frogs native to sub-Saharan Africa. Twenty species are currently described within it. The two best-known species of this genus are '' Xenopus laevis'' and '' Xenopus tropicalis'', which are commonly studied as model organisms for developmental biology, cell biology, toxicology, neuroscience and for modelling human disease and birth defects. The genus is also known for its polyploidy, with some species having up to 12 sets of chromosomes. Characteristics ''Xenopus laevis'' is a rather inactive creature. It is incredibly hardy and can live up to 15 years. At times the ponds that ''Xenopus laevis'' is found in dry up, compelling it, in the dry season, to burrow into the mud, leaving a tunnel for air. It may lie dormant for up to a year. If the pond dries up in the rainy season, ''Xenopus laevis'' may migrate long di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Described In 2008
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their biological life cycle, life cycle typically starts out as aquatic animal, aquatic larvae with gills known as tadpoles, but some species have devel ...

Frogs Of Africa
The fauna of Africa are all the animals living in Africa and its surrounding seas and islands. The more characteristic African fauna are found in the Afro-tropical realm. Lying almost entirely within the tropics, and stretching equally north and south of the equator creates favorable conditions for variety and abundance of wildlife. Africa is home to many of the world's most recognizable fauna such as lions‚ rhinoceroses‚ cheetahs‚ giraffes‚ antelope, hippopotamuses, leopards, zebras‚ and elephants, among many others. Origins and history of African fauna Whereas the earliest traces of life in fossil record of Africa date back to the earliest times, the formation of African fauna as we know it today, began with the splitting up of the Gondwana supercontinent in the mid-Mesozoic era. After that, four to six faunal assemblages, the so-called African Faunal Strata (AFSs) can be distinguished. The isolation of Africa was broken intermittently by discontinuous "filter routes" ...
