Austroglanis
''Austroglanis'' is the only genus in the catfish family Austroglanididae. This family was split off from the Bagridae catfish family. All three species of catfishes in the family Austroglanididae are endemic to southern Africa (South Africa and Namibia), and two species are threatened. These fish have three pairs of barbels (they lack nasal barbels). They have strong dorsal and pectoral fin spines. The adipose fin is small. Species There are currently three described species in this genus: * ''Austroglanis barnardi'' ( P. H. Skelton, 1981) (Barnard's rock-catfish) * ''Austroglanis gilli'' (Barnard, 1943) (Clanwilliam catfish) * ''Austroglanis sclateri The rock-catfish, ''Austroglanis sclateri'', is a species of catfish in the family Austroglanididae.

Austroglanis Barnardi
General ''Austroglanis barnardi'' is an endangered species of catfish (order Siluriformes). It is one of three members of the family Austroglanididae. It is also known as the spotted rock-catfish or Barnard's rock-catfish. Biology Not much is known about the biology of ''A. barnardi'' because of the discovery being so recent. It has a 12-year generation time but nothing more is known about reproduction within the species. It feeds on aquatic insects, benthic invertebrates and other small fishes. Habitat This species is endemic to South Africa and is found only in freshwater bodies of subtropical climate. It has only been recorded from the Thee, Noordhoeks and Hex Rivers, which are all small tributaries of the Clanwilliam Olifants River System in the Western Cape, South Africa. It is extremely uncommon in these two streams it inhabits. ''A. barnardi'' inhabits riffles among loosely bedded rocks and coarse sand. Its preferred water depth is between 10-60 centimeters.

Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Bagridae
The Bagridae are a family of catfish that are native to Africa ('' Bagrus'') and Asia (all other genera) from Japan to Borneo. It includes about 245 species. These fish are commonly known as naked catfishes or bagrid catfishes. Many large bagrids are important as a source of food. Some species are also kept as aquarium fishes. Physical characteristics The dorsal fin is preceded by a spine. The adipose fin is present and can have a relatively long base in some species. The pectoral fin spine can be serrated. The body is completely naked (they have no scales). The maximum length is about . Fishes of the family Bagridae have four pairs of well-developed barbels covered by a layer of taste bud-enriched epithelium. Taxonomy The taxonomy of this family has changed rapidly. Nelson (2006) comments how "the family is very different from that recognized in Nelson (1994)". Claroteidae and Austroglanididae contain species that were previously bagrids. Auchenoglanididae is considered by some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
