Sharpsnout Stingray
The sharpsnout stingray or wingfin stingray (''Dasyatis geijskesi'') is a species of stingray in the family Dasyatidae, found from off Venezuela to northern Brazil. It inhabits shallow, brackish water, shifting towards the coast in the dry season and away from it in the rainy season. Typically measuring across, this dark brown ray is easily identifiable by its long, projecting snout and elongated, acutely pointed pelvic fins. Its diet consists of bottom-dwelling invertebrates. Reproduction is aplacental viviparous, with females bearing one to three pups annually. Naturally uncommon and slow-reproducing, the sharpnose stingray is under pressure by both artisanal and commercial fisheries, leading the International Union for Conservation of Nature (IUCN) to assess it as critically endangered. Taxonomy and phylogeny Dutch ichthyologist Marinus Boeseman described the sharpsnout stingray in a 1948 issue of the scientific journal ''Zoologische Mededelingen'', based on a juvenile male ...

Colares Stingray
The Colares stingray, ''Dasyatis colarensis'', is a species of stingray in the family Dasyatidae, native to the shallow brackish waters of the Amazon River estuary in northern Brazil. This species inhabits inshore bays during the dry season and moves away from the coast in the rainy season. It is characterized by a rhomboid pectoral fin disk, elongated snout, and a dark band on the lower lip. A fairly large species, males and females attain disk widths of and respectively. Females give birth to 1–4 young, possibly annually. Colares stingrays are both targeted and caught as bycatch by Brazilian artisanal and commercial fisheries; these pressures coupled with its small range and slow reproductive rate has led the International Union for Conservation of Nature (IUCN) to list this species as critically endangered. Taxonomy The Colares stingray was described by Hugo Santos, Ulisses Gomes, and Patricia Charvet-Almeida in 2004, in the scientific journal ''Zootaxa''. The specific ...

Pincushion Ray
The pincushion ray (''Dasyatis ukpam'') or thorny freshwater stingray, is a little-known species of stingray in the family Dasyatidae, found in the rivers and lakes of West and Middle Africa. A heavy-bodied ray measuring up to across, this species can be distinguished by its rounded pectoral fin disk, reduced or absent stinging tail spine, and—in adults—numerous stout thorns covering its back and tail. In lieu of a long tail spine as in other stingrays, the pincushion ray employs these thorny denticles in defense. Seldom encountered since it was originally described, this species has been assessed as Critically Endangered by the International Union for Conservation of Nature (IUCN). Taxonomy John Alexander Smith scientifically described the pincushion ray in 1863, in ''Proceedings of the Royal Physical Society of Edinburgh''. He named it ''ukpam'', as that is the local indigenous name for freshwater stingrays. Because he saw the single, reduced tail spine of this ray as an ...

Daisy Stingray
The daisy stingray, ''Dasyatis margarita'', is a little-known species of stingray in the family Dasyatidae, found in shallow waters along the coast of West Africa. This species typically grows to across and has a rounded pectoral fin disc and (in adults) a wide band of dermal denticles over its back. It is characterized by a greatly enlarged, nacreous denticle in the middle of its back called a "pearl spine"; this feature is shared with the similar but much smaller pearl stingray (''D. margaritella''), which has often been confused with this species. The daisy stingray feeds mainly on crustaceans and exhibits aplacental viviparity, with litters of 1–4 young. Heavily pressured by fisheries and possibly habitat degradation, this once-common species is declining and has been assessed as Vulnerable by the International Union for Conservation of Nature (IUCN). Taxonomy British zoologist Albert Günther originally described the daisy stingray as ''Trygon margarita'', in his 187 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fontitrygon Margaritella
The pearl stingray (''Dasyatis margaritella'') is a little-known species of stingray in the family Dasyatidae, found in shallow coastal waters from Mauritania to Angola. Growing to across, this species has a rounded pectoral fin disc with a pointed snout, and a wide band of dermal denticles over the back in adults. It closely resembles and is often confused for the much larger daisy stingray (''D. margarita''); both species are characterized by the presence of an enlarged, nacreous denticle in the middle of the back called a "pearl spine". The International Union for Conservation of Nature (IUCN) assesses the pearl stingray's conservation status as Near Threatened, but it is likely that most of the historically reported fishery catches of the daisy stingray were in fact of this species. Taxonomy and phylogeny Prior to being described by Leonard Compagno and Tyson Roberts, in a 1984 paper for the ''Proceedings of the California Academy of Sciences'', the pearl stingray was gene ...

Niger Stingray
The Niger stingray or smooth freshwater stingray (''Dasyatis garouaensis'') is a species of stingray in the family Dasyatidae, native to rivers in Nigeria and Cameroon. Attaining a width of , this species can be distinguished by its thin, almost circular pectoral fin disk, slightly projecting snout tip, and mostly smooth skin with small or absent dermal denticles. The Niger stingray feeds on aquatic insect larvae and is ovoviviparous. The long stinging spine on the tail of this ray can inflict a painful wound. It has been assessed as Critically Endangered by the International Union for Conservation of Nature (IUCN), as its numbers are declining in some areas and it faces heavy fishing pressure and habitat degradation. Taxonomy The original description of the Niger stingray was published by Alfred Stauch and M. Blanc in 1962, in the scientific journal ''Bulletin du Muséum National d'Histoire Naturelle (Série 2)''. The specific epithet ''garouaensis'' refers to the city of Garou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dasyatis
''Dasyatis'' (Greek δασύς ''dasýs'' meaning rough or dense and βατίς ''batís'' meaning skate) is a genus of stingray in the family Dasyatidae that is native to the Atlantic, including the Mediterranean. In a 2016 taxonomic revision, many of the species formerly assigned to ''Dasyatis'' were reassigned to other genera (''Bathytoshia'', ''Fontitrygon'', ''Hemitrygon'', '' Hypanus'', ''Megatrygon'' and ''Telatrygon'').

Stingray
Stingrays are a group of sea rays, which are cartilaginous fish related to sharks. 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 river stingrays and a number of whiptail stingrays (such as the Niger stingray (''Fontitrygon garouaensis'')) are restricted to fresh water. Most myliobatoids are demersa ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
