Katria Katria
''Katria'' is a genus of freshwater fish in the cichlid family. It contains the single species ''Katria katria'', a vulnerable species from the Mangoro and Nosivolo Rivers in east-central Madagascar, that was formerly included in the genus ''Ptychochromoides''.Stiassny, M., and Sparks, J.

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

Fish Described In 1997
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Freshwater Fish Of Madagascar
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water i ...

Ptychochrominae
The Ptychochrominae are a subfamily in the cichlid family of fish. It includes about 14 species. They are restricted to lakes and rivers in Madagascar, and the majority are threatened. Most cichlid genera native to Madagascar are included in this subfamily; the only exceptions are ''Paretroplus ''Paretroplus'' is a genus of fishes in the cichlid family, all of which are endemic to lakes and rivers of Madagascar.

Durrell Wildlife Conservation Trust
Durrell Wildlife Conservation Trust is a conservation organization with a mission to save species from extinction. Gerald Durrell founded the Jersey Wildlife Preservation Trust as a charitable institution in 1963 with the dodo as its symbol. The trust was renamed Durrell Wildlife Conservation Trust in its founder's honor on 26 March 1999. Its patron is Princess Anne, the Princess Royal. Its headquarters are at Les Augrès Manor on the isle of Jersey in the English Channel. The grounds of Les Augrès Manor form the Durrell Wildlife Park, which was originally established by Gerald Durrell in 1959 as a sanctuary and breeding center for endangered species. The zoological park was known as the ''Jersey Zoo'' at that time. As of 2016, the zoo was home to more than one hundred species of reptiles, birds and mammals, many of which are designated as endangered in the wild. Despite strong resistance to his ideas from much of the zoological community, in 1959 Gerald Durrell succeeded in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oxylapia
''Oxylapia'' is a genus of freshwater fish in the family Cichlidae. It contains the single species ''Oxylapia polli'', known locally as the songatana. It is an endangered species, endemic to the Marolambo Rapids in the Nosivolo River (a tributary of the Mangoro River) in east-central Madagascar. It is threatened by habitat loss and sedimentation caused by deforestation. The only other monotypic cichlid genus in Madagascar is ''Katria'', and it is restricted to the same region as ''Oxylapia''. In 2010, the Nosivolo River was designated as a Ramsar Site.Durrell Wildlife Conservation Trust (20 September 2010). Nosivolo is designated as Madagascar's first riverine Ramsar site.'
