Hypanus
''Hypanus'' is a genus of stingrays in the family Dasyatidae from warmer parts of the East Pacific and Atlantic, including the Caribbean and Gulf of Mexico. The genus was previous regarded as a junior synonym of the genus ''Dasyatis''. Species The placement of ''H. marianae'' and ''H. rudis'' within the genus is provisional, pending more thorough investigation. *''Hypanus americanus'' (Hildebrand & Schroeder, 1928) (Southern stingray) *'' Hypanus berthalutzae'' Petean, Naylor & Lima, 2020 (Lutz's stingray) *'' Hypanus dipterurus'' (Jordan & Gilbert, 1880) (Diamond stingray) *'' Hypanus guttatus'' (Bloch & Schneider, 1801) (Longnose stingray) *'' Hypanus longus'' ( Garman, 1880) (Longtail stingray) *'' Hypanus marianae'' (Gomes, Rosa & Gadig, 2000) (Brazilian large-eyed stingray) *'' Hypanus rudis'' ( Günther, 1870) (Smalltooth stingray) *''Hypanus sabinus The Atlantic stingray (''Dasyatis sabina'') is a species of Myliobatiformes, stingray in the family (biology), family Da ...

Southern Stingray
The southern stingray (''Hypanus americanus'') is a whiptail stingray found in tropical and subtropical waters of the Western Atlantic Ocean from New Jersey to southern Brazil. It has a flat, diamond-shaped disc, with a mud brown, olive, and grey dorsal surface and white underbelly (ventral surface). The barb on its tail is serrated and covered in a venomous mucus, used for self-defense. Description The southern stingray is adapted for life on the sea bed. Its flattened, diamond-shaped body is more angular than other rays. In public aquariums, female southern stingrays have been seen biting one another on the edges of their fins. Reproduction has also been known to occur within large public aquariums. Gallery File:Dasyatis americana bonaire.jpg, A southern stingray in Bonaire.

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 ...

Bluntnose Stingray
The bluntnose stingray or Say's stingray (''Hypanus say'', often misspelled ''sayi'') is a species of stingray in the family Dasyatidae, native to the coastal waters of the western Atlantic Ocean from the U.S. state of Massachusetts to Venezuela. It is a bottom-dwelling species that prefers sandy or muddy habitats deep, and is migratory in the northern portion of its range. Typically growing to across, the bluntnose stingray is characterized by a rhomboid pectoral fin disc with broadly rounded outer corners and an obtuse-angled snout. It has a whip-like tail with both an upper keel and a lower fin fold, and a line of small tubercles along the middle of its back. More active at night than during the day when it is usually buried in sediment, the bluntnose stingray is a predator of small benthic invertebrates and bony fishes. This species is aplacental viviparous, in which the unborn young are nourished initially by yolk, and later histotroph ("uterine milk") produced by their ...

Diamond Stingray
The diamond stingray (''Dasyatis dipterura'') is a species of stingray in the family Dasyatidae. It is found in the coastal waters of the eastern Pacific Ocean from southern California to northern Chile, and around the Galápagos and Hawaiian Islands. This bottom-dweller generally inhabits sandy or muddy flats near rocky reefs and kelp forests, to a depth of , though off Hawaii it may range considerably deeper. As its common name suggests, this species has an angular, diamond-shaped pectoral fin disc that is plain brown or gray above, with rows of tubercles along the midline and on the "shoulders". The long, whip-like tail has both dorsal and ventral fin folds, which distinguish this ray from the closely similar longtail stingray (''D. longa''). It typically grows to across. When searching for food, diamond stingrays may form groups of up to hundreds of individuals. It is most active at night and preys mainly on burrowing invertebrates and small bony fishes, which are ext ... [...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'').

Smalltooth Stingray
The smalltooth stingray (''Dasyatis rudis'') is an obscure species of stingray in the family Dasyatidae, found in the Gulf of Guinea. It is known only from a stuffed specimen described by Albert Günther in 1870, which has since been lost. In 1970, Springer and Collette assigned a jaw, tail, and two embryos from off Sierra Leone to this species, but later investigation found that the jaw belonged to a guitarfish, and the tail and embryos to a different species, possibly ''Dasyatis hastata ''Dasyatis hastata'' is a species of stingray in the family Dasyatidae.

Brazilian Large-eyed Stingray
The Brazilian large-eyed stingray, ''Dasyatis marianae'', is a species of stingray in the family Dasyatidae. Endemic to northeastern Brazil, adults of this species inhabit shallow coral and sandstone reefs while the young are also found near beaches and in estuaries. This stingray measures up to across and can be identified by its large eyes, equally long fin folds above and below the tail, and distinctive coloration consisting of various dark brown markings on a yellowish-brown background above, and two pairs of dark brown blotches on a white background below. Reproduction is aplacental viviparous, with females giving birth to one young at a time, twice a year, and using sandbanks as nursery areas. The Brazilian large-eyed stingray is collected by artisanal fisheries and for the ornamental fish trade. Taxonomy and phylogeny The Brazilian large-eyed stingray was described by Ulisses Gomes, Ricardo Rosa, and Otto Gadig in 2000, in the scientific journal ''Copeia''. The authors ...

Longtail Stingray
The longtail stingray (''Dasyatis longa'', often misspelled ''longus''), is a species of stingray in the family Dasyatidae, found in the eastern Pacific Ocean from Baja California to Colombia. It inhabits sandy habitats down to a depth of . Measuring up to across, this species has a rhomboid pectoral fin disc, a lower (but not upper) fin fold on the tail, and numerous dermal denticles along the back and behind the stinging spine. The longtail stingray feeds mainly on bottom-dwelling bony fishes and crustaceans. It is aplacental viviparous, with females giving birth to 1–5 young in late summer. It is caught for food, likely throughout its range, but specific fishery data is lacking. Taxonomy and phylogeny American zoologist Samuel Garman published the original description of the longtail stingray in an 1880 issue of the scientific journal ''Bulletin of the Museum of Comparative Zoology''. He gave it the name ''Trygon longa'', in reference to the long tail, and designated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longnose Stingray
The longnose stingray (''Dasyatis guttata'') is a species of stingray in the family Dasyatidae, native to the western Atlantic Ocean from the southern Gulf of Mexico to Brazil. Found in coastal waters no deeper than , this demersal species favors muddy or sandy habitats. The longnose stingray is characterized by its angular, rhomboid pectoral fin disc, moderately projecting snout, and whip-like tail with a dorsal keel and ventral fin fold. It typically grows to across and is brownish above and light-colored below. Longnose stingrays feed mainly on bottom-dwelling invertebrates and small bony fishes. Reproduction is aplacental viviparous, with females bearing two litters of 1–2 pups per year. The young are born in relatively fresh water, move into saltier water as juveniles, and then back into fresher water as adults. This species is valued by commercial and recreational fishers in many parts of its range, and utilized for meat, gelatin, oil, and even the aquarium trade. ...

Atlantic Stingray
The Atlantic stingray (''Dasyatis sabina'') is a species of stingray in the family Dasyatidae, common along the Atlantic coast of North America from Chesapeake Bay to Mexico, including brackish and freshwater habitats. It may be distinguished from other stingrays in the area by its relatively elongated snout. This species is of little commercial importance, other than for sale in the aquarium industry. Taxonomy and phylogeny The Atlantic stingray was described by French naturalist Charles Alexandre Lesueur as ''Trygon sabina'', in an 1824 volume of the ''Journal of the Academy of Natural Sciences of Philadelphia''. He based his account on a damaged male specimen collected by American naturalist Titian Ramsay Peale during the Academy's 1817 expedition to Florida. Since then, various authors have included this species in the obsolete genera ''Pastinaca'', ''Dasybatus'' (or the variants ''Dasibatis'' and ''Dasybatis''), and ''Amphotistius'', all of which were eventually synony ...

Junior Synonym
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Marcus Elieser Bloch
Marcus Elieser Bloch (1723–1799) was a German physician and naturalist who is best known for his contribution to ichthyology through his multi-volume catalog of plates illustrating the fishes of the world. Brought up in a Hebrew-speaking Jewish family, he learned German and Latin and studied anatomy before settling in Berlin as a physician. He amassed a large natural history collection, particularly of fish specimens. He is generally considered one of the most important ichthyologists of the 18th century, and wrote many papers on natural history, comparative anatomy, and physiology. Life Bloch was born at Ansbach in 1723 where his father was a Torah writer and his mother owned a small shop. Educated at home in Hebrew literature he became a private tutor in Hamburg for a Jewish surgeon. Here he learned German, Latin and anatomy. He then studied medicine in Berlin and received a doctorate in 1762 from Frankfort on the Oder with a treatise on skin disorders. He then became a gen ...
