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'').

Dasyatis Pastinaca
The common stingray (''Dasyatis pastinaca'') is a species of stingray in the family Dasyatidae, found in the northeastern Atlantic Ocean and the Mediterranean and Black Seas. It typically inhabits sandy or muddy habitats in coastal waters shallower than , often burying itself in sediment. Usually measuring across, the common stingray has a diamond-shaped pectoral fin disc slightly wider than long, and a whip-like tail with upper and lower fin folds. It can be identified by its plain coloration and mostly smooth skin, except for a row of tubercles along the midline of the back in the largest individuals. The predominant prey of the common stingray are bottom-dwelling crustaceans, though it also takes molluscs, polychaete worms, and small bony fishes. It is aplacental viviparous: the embryos are nourished by yolk and later histotroph ("uterine milk") produced by the mother. Females bear 4–9 young twice per year in shallow water, after a gestation period of four months. The co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Stingray
The blue stingray (''Dasyatis chrysonota'') is a species of whiptail stingray of the family Dasyatidae often found in the coastal waters of southern Africa. Distribution and similar species The species' common geographical distribution ranges from St. Lucia on the southern tip of Africa up to Angola and a depth distribution ranging from the surf zone to 110m depth. Although this is the typical geographical distribution, the species has also been found off the Mediterranean coast of Israel and in the Gulf of Gabčs in southern Tunisia. ''D. chrysonota'' is easily distinguishable from other stingray species by the appearance of faint blue splotches and lines on its light-brown triangular disc body. Growth and appearance Their disc can reach a maximum width of approximately 75 cm. There are four size classes: small, medium, large, and very large. The ranges of each size class are as follows: small = 60 cm. The size of male and female blue stingray show no distinction f ...

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 ...

Groovebelly Stingray
The groovebelly stingray (''Dasyatis hypostigma''), referred to as the butter stingray by fishery workers, is a species of stingray in the family Dasyatidae. It is found over sandy or muddy bottoms in shallow coastal waters off southern Brazil, and probably Uruguay and Argentina. The groovebelly stingray can be distinguished by a prominent "W"-shaped furrow on its underside behind the last pair of gill slits, as well as completely smooth skin in all but the largest individuals. It reaches a maximum known width of . This species is aplacental viviparous, with one observed female gestating two young. The main threat to its population is likely bycatch mortality from shrimp trawlers, although habitat degradation is also a concern. Taxonomy Hugo Santos and Marcelo de Carvalho formally described the groovebelly stingray in a 2004 volume of ''Boletim do Museu Nacional'', giving it the name ''Dasyatis hypostigma'', from the Greek ''hypo'' ("ventral") and ''stigma'' ("mark").

Dasyatis Marmorata
''Dasyatis marmorata'', the marbled stingray, is a species of stingray of the family Dasyatidae. Its geographic range covers the central and south-eastern Atlantic, from Morocco to South Africa. It is also present in the coastal waters of southern Mediterranean Sea and the Levantine Basin. This bottom-dweller generally inhabits sandy or muddy flats near rocky reefs and kelp forests Kelp forests are underwater areas with a high density of kelp, which covers a large part of the world's coastlines. Smaller areas of anchored kelp are called kelp beds. They are recognized as one of the most productive and dynamic ecosystems on Ea ..., to a depth of 50 m (164 ft).

Megatrygon
The smalleye stingray (''Megatrygon microps'') is a large species of stingray in the family Dasyatidae, measuring up to across. Rare but widely distributed, it is found in the Indo-Pacific from Mozambique to India to northern Australia. This species may be semi-pelagic in nature, inhabiting both deeper waters and shallow coastal reefs and estuaries. It is characterized by a diamond-shaped pectoral fin disc much wider than long, a tail that is broad and flattened in front of the spine but whip-like behind, and large white spots over its back. The very wide shape of the smalleye stingray differs from that of most other members of its family, and may reflect a mode of swimming similar to other rays such as manta rays. This species is aplacental viviparous, with litter sizes perhaps as small as one pup. A handful of smalleye stingrays are caught incidentally by commercial fisheries across its range. At present there is insufficient data for the International Union for Conservation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
