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'' (subfamily Etroplinae) and ''Paratilapia'' (sometimes included in the Ptychochrominae, but likely belongs in its own subfamily). Abstract Abstract Genera The following genera are included in the subfamily Ptychochrominae: *'' Katria'' Stiassny & Sparks, 2006 *'' Oxylapia'' Kiener & Maugé, 1966 *''Paratilapia ''Paratilapia'' is a genus of cichlids generally restricted to Madagascar.

Cichlidae
Cichlids () are a large, diverse, and widespread family of percomorph fish in the family Cichlidae, order Cichliformes. At least 1,760 species have been scientifically described, making it one of the largest vertebrate families, with only the Cyprinidae being more speciose. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. They are native to the Neotropics, Africa (including Madagascar), the Middle East, and the Indian subcontinent, although some species have been introduced worldwide. Many cichlids, particularly tilapia, are important food fishes, while others, such as the '' Cichla'' species, are valued game fish. The family also includes many popular freshwater aquarium fish kept by hobbyists, including the angelfish, oscars, and discus. Cichlids have the largest number of endangered species among vertebrate families, most in the haplochrom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paratilapia
''Paratilapia'' is a genus of cichlids generally restricted to Madagascar. These are large, dark cichlids densely covered in light spots. An additional very poorly known species from the Congo River basin in mainland Africa is sometimes also placed in the genus, but this is highly questionable and arguably it is better placed in the "Wastebasket taxon, wastebasket genus" ''Haplochromis'' for the time being.Greenwood (1979). ''Towards a phyletic classification of the 'genus' Haplochromis (Pisces, Cichlidae) and related taxa.'' Bulletin of the British Museum (Natural History) Zoology 35(4): 265-322 Taxonomy Phylogenetic analyses of DNA sequence and Morphology (biology), morphological data have hitherto been unable to resolve the relationships of the genus to satisfaction. For example, sequence data from mtDNA MT-RNR2, 16S rRNA and Cytochrome c oxidase, COI disagree regarding its placement, (2004): Molecular phylogeny and biogeography of the Malagasy and South Asian cichlids (Teleo ...

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.'

''American Museum Novitates, 3535: 1-56.'' Most species in this genus are threatened, and '' P. onilahy'' is probably extinct. Most reach a length of , but '' P. insolitus'' reaches , while ''P. grandidieri'' and '' P. oligacanthus'' reach and respectively. The largest species was ''P. onilahy'' which may have reached as much as if reports of fishermen are to be believed.

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. The term excludes seawater and brackish water, but 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. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Franz Steindachner
Franz Steindachner (11 November 1834 in Vienna – 10 December 1919 in Vienna) was an Austrian zoologist, ichthyologist, and herpetologist. He published over 200 papers on fishes and over 50 papers on reptiles and amphibians. Steindachner described hundreds of new species of fish and dozens of new amphibians and reptiles. At least seven species of reptile have been named after him. Work and career Being interested in natural history, Steindachner took up the study of fossil fishes on the recommendation of his friend Eduard Suess (1831–1914). In 1860 he was appointed to the position of director of the fish collection at the Natural History Museum, Vienna, a position which had remained vacant since the death of Johann Jakob Heckel (1790–1857). (in German). Steindachner's reputation as an ichthyologist grew, and in 1868 he was invited by Louis Agassiz (1807–1873) to accept a position at the Museum of Comparative Zoology at Harvard University.
