Himantura Signifer
''Himantura'' is a genus of stingray in the family Dasyatidae that is native to the Indo-Pacific. In a 2016 taxonomic revision, many of the species formerly assigned to ''Himantura'' were reassigned to other genera (''Brevitrygon'', ''Fluvitrygon'', ''Maculabatis'', '' Pateobatis'', ''Styracura'' and '' Urogymnus''). Species Twelve extant species are currently recognized as valid, formerly four or five species. * ''Himantura alcockii'' ( Annandale, 1909) (Pale-spot whip ray) * ''Himantura australis'' (Last, White & Naylor, 2016) (Australian whipray) * ''Himantura fava'' (Annandale, 1909) (Honeycomb whipray) * ''Himantura fluviatilis'' (Hamilton, 1822) (Ganges whipray) * ''Himantura krempfi'' ( Chabanaud, 1923) (Marbled freshwater whip ray) * ''Himantura leoparda'' ( Manjaji-Matsumoto & Last, 2008) (Leopard whipray) * ''Himantura marginata'' ( Blyth, 1860) (Blackedge whipray) * '' Himantura menoni'' (Sahni & Mehrotra, 1981) * '' Himantura microphthalma'' ( J.

Oligocene
The Oligocene ( ) is a geologic epoch (geology), epoch of the Paleogene Geologic time scale, Period that extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from Ancient Greek (''olígos'') 'few' and (''kainós'') 'new', and refers to the sparsity of Neontology, extant forms of Mollusca, molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major chang ...

Himantura Alcockii
''Himantura alcockii'', the pale-spot whip ray, is a species of stingray in the family Dasyatidae. It is found in coastal regions including estuaries, in the Indian Ocean. As presently defined, it is probably a species complex. Taxonomy The species has had a chequered taxonomic history. The IUCN Red List still lists ''H. alcockii'' as a synonym of the Whitespotted whipray, which is now reallocated to ''Maculabatis''. Human interactions Over 50% of the total ray catch landed at Mumbai Mumbai ( ; ), also known as Bombay ( ; its official name until 1995), is the capital city of the Indian state of Maharashtra.

Himantura Marginata
The blackedge whipray (''Himantura marginata'') is a little-known species of stingray in the family Dasyatidae, found in the coastal waters of the Bay of Bengal and the Gulf of Mannar. Attaining a disc width of , this species has a diamond-shaped disc with two small concavities on either side of the snout tip, and a long, whip-like tail without tail folds. It is characterized by large thorns with star-shaped bases scattered over the disc, and by the wide, black marginal bands on the underside of the disc. The International Union for Conservation of Nature (IUCN) currently lacks sufficient data to assess the blackedge whipray beyond Data Deficient. Taxonomy English zoologist Edward Blyth described the blackedge stingray as ''Trygon marginatus'', in an 1860 issue of the ''Journal and Proceedings of the Asiatic Society of Bengal''. Blyth based his account on a specimen across obtained from a fish market in Calcutta, which has since been lost. The specific epithet ''marginatus'' mea ...

Himantura Leoparda
The leopard whipray (''Himantura leoparda'') is a little-known species of stingray in the family Dasyatidae, found in the Indian and Pacific Oceans from the Andaman Sea to the Coral Triangle. It is found close to shore at depths shallower than , over soft substrates. Attaining a width of , this species has a diamond-shaped pectoral fin disc with a pointed snout and an extremely long, whip-like tail without fin folds. Adult rays have a leopard-like dorsal pattern of dark brown rings on a yellowish brown background, as well as a row of enlarged, heart-shaped dermal denticles along the midline of the disc. Newborns and small juveniles have large, solid dark spots and few denticles. The leopard whipray is caught by fisheries in many parts of its range, primarily for meat. Taxonomy Historically, the leopard stingray has been conflated with the reticulate whipray (''H. uarnak'') or the honeycomb whipray (''H. undulata'' or its synonym, ''H. fava'') in literature; all three are closel ...

Paul Chabanaud
Paul Chabanaud (30 November 1876, in Versailles – 27 February 1959) was a French ichthyologist and herpetologist. Beginning in 1915, he worked as a volunteer under zoologist Louis Roule at the ''Muséum National d'Histoire Naturelle'' in Paris. In 1919–1920, he undertook a scientific expedition to French West Africa (Senegal, Guinea) on behalf of the museum, during which he collected thousands of zoological specimens. Following his return to Paris, he served as a preparator in the laboratory of biologist Jean Abel Gruvel at the museum. He specialized in the anatomy and systematics of the flatfish (order Pleuronectiformes) and was the taxonomic authority of many herpetological and ichthyological species.The Eponym Dictionary of Reptiles by Bo Beolens, Michael Watkins, Michael Grayson < ...

Francis Buchanan-Hamilton
Francis Buchanan (15 February 1762 – 15 June 1829), later known as Francis Hamilton but often referred to as Francis Buchanan-Hamilton, was a Scottish surgeon, surveyor and botanist who made significant contributions as a geographer and zoologist while living in India. He did not assume the name of Hamilton until three years after his retirement from India. The standard botanical author abbreviation Buch.-Ham. is applied to plants and animals he described, though today the form "Hamilton, 1822" is more usually seen in ichthyology and is preferred by Fishbase. Early life Francis Buchanan was born at Bardowie, Callander, Perthshire where Elizabeth, his mother, lived on the estate of Branziet; his father Thomas, a physician, came in Stirling, Spittal and claimed the chiefdom of the name of Clan Buchanan, Buchanan and owned the Leny estate. Francis Buchanan matriculated in 1774 and received an MA in 1779. As he had three older brothers, he had to earn a living from a profession, ...

Himantura Fluviatilis
''Himantura fluviatilis'', the Ganges whip ray, is an obscure species of stingray in the family Dasyatidae, apparently endemic to the Ganges River system and adjacent marine waters. With an oval pectoral fin disc and long projecting snout, it closely resembles, and may be the same species as ''Himantura chaophraya'' (a synonym of the Giant freshwater stingray of Southeast Asia). Growing to across, it is a plain dark colour above, and lighter below with wide dark bands on the lateral disc margins. The International Union for Conservation of Nature (IUCN) has listed this species as Endangered, as it faces overfishing and habitat degradation within its heavily populated range. Taxonomy Scottish physician, geographer, and naturalist Francis Buchanan-Hamilton, in his 1822 account of Ganges River fishes, made reference to a species of freshwater stingray he named ''Raia fluviatilis''. However, he deferred making a description until an illustration could be made, an opportunity that ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Himantura Fava
''Himantura fava'', the honeycomb whipray, is a species of stingray in the family Dasyatidae. It is found in coastal regions including estuaries, in the Indo-Pacific off India, Indonesia, and the Gulf of Thailand. As presently defined, it is probably a species complex. Taxonomy The first known specimens of this species were two wide adult females collected near Orissa, India by the steamer ''Golden Crown'', and described by Scottish zoologist Nelson Annandale in a 1909 issue of ''Memoirs of the Indian Museum''. He remarked that it was closely allied to '' Himantura uarnak'' with the main distinguishing feature being the mouth. Smaller differences included a yellow, as opposed to white, reticulated pattern on the dorsal surface, and the lack of stellate denticles. The species has had a confused taxonomic history. Many sources still consider ''H. fava'' to be a synonym of '' Himantura undulata''. Description This species is characterized by absence of skin fold on the ventral ...
