Glyphis Hastalis

	Glyphis Hastalis ''Glyphis hastalis'' is a species of extinct river shark from Great Britain. Modern relatives include the Ganges shark and speartooth shark The speartooth shark (''Glyphis glyphis'') is a rare species of river shark, belonging to the family Carcharhinidae. It inhabits coastal marine waters and tidal reaches of large tropical rivers in northern Australia and New Guinea. Despite bein ....

	River Shark ''Glyphis'' is a genus in the family Carcharhinidae, commonly known as the river sharks. They live in rivers or coastal regions in and around south-east Asia and parts of Australia. Taxonomy This genus contains only three extant species. Further species could easily remain undiscovered, due to their secretive habits. This genus was thought to contain five different species, but recent studies on molecular data revealed that the species '' Glyphis gangeticus'' has an irregular distribution in the Indo-West Pacific region. Species The recognized species in this genus are: * '' Glyphis gangeticus'' ( J. P. Müller & Henle, 1839) (Ganges shark) * '' Glyphis garricki'' L. J. V. Compagno, W. T. White & Last, 2008 (northern river shark) * ''Glyphis glyphis'' ( J. P. Müller & Henle, 1839) (speartooth shark) * †''Glyphis hastalis'' Agassiz, 1843 * †''Glyphis pagoda'' (Noetling, 1901) Distribution and habitat Their precise geographic range is uncertain, but the known species are d ...

	Ganges Shark The Ganges shark (''Glyphis gangeticus'') is a critically endangered species of requiem shark found in the Ganges River (Padma River) and the Brahmaputra River of Bangladesh and India. It is often confused with the more common bull shark (''Carcharhinus leucas''), which also inhabits the Ganges River and is sometimes incorrectly referred to as the Ganges shark. The genus is currently considered to contain three recent species; genetic evidence has shown that both the Borneo river shark (''G. fowlerae'') and Irrawaddy river shark (''G. siamensis'') should be regarded as synonyms of the Ganges shark, expanding the range of the species to Pakistan, Myanmar, Borneo, and Java. While the other members of the genus ''Glyphis'' occur in coastal marine waters as well as rivers, the Ganges shark is found only in fresh water, making it the world's only exclusively freshwater shark. The species remains poorly known and very rare. Taxonomy Formerly the Borneo river shark (''Glyphis fowlerae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Speartooth Shark The speartooth shark (''Glyphis glyphis'') is a rare species of river shark, belonging to the family Carcharhinidae. It inhabits coastal marine waters and tidal reaches of large tropical rivers in northern Australia and New Guinea. Despite being a member of the river shark genus, it is also found in near-shore marine waters, favoring highly turbid environments over a wide range of salinities. This robustly built, gray-colored shark is characterized by a short and broad snout, tiny eyes, a relatively large second dorsal fin, and a black blotch beneath each pectoral fin near the tip. Another identifying trait is its teeth, which are large, triangular, and serrated in the upper jaw and narrow, spear-like, and serrated only near the tips in the lower jaw. Adults grow to about long. Preying on demersal bony fishes and crustaceans, the speartooth shark is adapted for hunting in near-complete darkness. It is not as active as other requiem sharks, moving upstream and downstream with ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
