Himantura
''Himantura'' is a genus of stingray in the family (biology), family Dasyatidae that is native to the Indo-Pacific. In a 2016 Taxonomy (biology), 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'' (Nelson Annandale, Annandale, 1909) (Pale-spot whip ray) * ''Himantura australis'' (Peter R.

Reticulate Whipray
The reticulate whipray or honeycomb stingray (''Himantura uarnak'') is a species of stingray in the family Dasyatidae. It inhabits coastal waters in the western Indian Ocean including the Red Sea, Natal and the Arabian Sea; also a Lessepsian transmigrant in the eastern Mediterranean. A large species reaching in width, the reticulate whipray has a diamond-shaped pectoral fin disc and an extremely long tail without fin folds. Both its common name, common and scientific names refer to its ornate dorsal color pattern of many small, close-set dark spots or reticulations on a lighter background. However, the reticulate whipray is only one of several large spotted stingrays in the Indo-Pacific which, coupled with the variability of its coloration with age and locality, has resulted in a great deal of Taxonomy (biology), taxonomic confusion. Often encountered resting on the bottom during daytime, the reticulate whipray is a predator of benthic, bottom-dwelling invertebrates and bony fish ...

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 ...

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 ...

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 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 Australis
''Himantura australis'', the Australian whipray, is a type of whiptail stingray found mainly in Australia and south of New Guinea island. This species is a minor bycatch and usually released back to ocean by Australian trawlers, although it might be retained for human consumption by the New Guinean locals. Description This species can be distinguished from several characteristics, such as weakly rhomboidal-shaped disc, short preorbital snout, narrowly rounded lateral apices, yellow-pale brown body color, white-colored underside, and fully covered in scattered dark brown speckles or reticulations. The maximum size of the female specimen is 140 cm disc width. Habitat & distribution This species distribution range encompasses Northern Territory, Western Australia, and Queensland in Australia, and both Indonesian Papua and the sovereign Papua New Guinea Papua New Guinea, officially the Independent State of Papua New Guinea, is an island country in Oceania that comprises th ...

Stingray
Stingrays are a group of sea Batoidea, rays, a type of cartilaginous fish. They are classified in the suborder Myliobatoidei of the order Myliobatiformes and consist of eight families: Hexatrygonidae (sixgill stingray), Plesiobatidae (deepwater stingray), Urolophidae (stingarees), Urotrygonidae (round rays), Dasyatidae (whiptail stingrays), Potamotrygonidae (river stingrays), Gymnuridae (butterfly rays) and Myliobatidae (eagle rays). There are about 220 known stingray species organized into 29 genera. Stingrays are common in coastal tropical and subtropical marine waters throughout the world. Some species, such as the thorntail stingray (''Dasyatis thetidis''), are found in warmer temperate oceans and others, such as the deepwater stingray (''Plesiobatis daviesi''), are found in the deep ocean. The Potamotrygonidae, river stingrays and a number of whiptail stingrays (such as the Niger stingray (''Fontitrygon garouaensis'')) are restricted to fresh water. Most myliobatoids are d ...
