Dasyatis 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.
The giant freshwater stingray is a species of stingray in the family Dasyatidae. It is found in large rivers and estuaries in Southeast Asia and Borneo, though historically it may have been more widely distributed in South and Southeast Asia. The largest freshwater fish and the largest stingray in the world, this species grows up to 2.2 m (7.2 ft) across and can reach up to 300 kg (660 lb) in weight. It has a relatively thin, oval pectoral fin disc that is widest anteriorly, and a sharply pointed snout with a protruding tip. Its tail is thin and whip-like, and lacks fin folds. This species is uniformly grayish brown above and white below; the underside of the pectoral and pelvic fins bear distinctive wide, dark bands on their posterior margins.
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.
The chupare stingray or Caribbean whiptail stingray is a species of stingray in the family Potamotrygonidae, found in the western Atlantic Ocean from the Gulf of Campeche to Brazil, including the Antilles. The presence of this species in the Gulf of Mexico has not been confirmed. It also occurs in the Bahamas. It usually inhabits sandy substrates, sometimes near coral reefs, and is an infrequent visitor to the Amazon River estuary. Leonard Compagno doubted the taxonomic validity of this species in his 1999 Checklist of Living Elasmobranchs.
The porcupine ray is a rare species of stingray in the family Dasyatidae. This bottom-dweller is found throughout the tropical Indo-Pacific, as well as off West Africa. It favors sand, coral rubble, and seagrass habitats in inshore waters to a depth of 30 m (100 ft). A large and heavy-bodied species reaching 1.2–1.5 m (3.9–4.9 ft) in width, the porcupine ray has a nearly circular, plain-colored pectoral fin disc and a thin tail without any fin folds. Uniquely within its family, it lacks a venomous stinging spine. However, an adult ray can still defend itself ably with the many large, sharp thorns found over its disc and tail.
The whiptail stingrays are a family, the Dasyatidae, of rays in the order Myliobatiformes. They are found worldwide in tropical to temperate marine waters, and a number of species have also penetrated into fresh water in Africa, Asia, and Australia. Members of this family have flattened pectoral fin discs that range from oval to diamond-like in shape. Their common name comes from their whip-like tails, which are much longer than the disc and lack dorsal and caudal fins. All whiptail stingrays, except the porcupine ray, have one or more venomous stings near the base of the tail, which is used in defense. In order to sting their victims, they jerk their tails as the stinger falls off and stays in the wound that they have created. The stinger of a whiptail stingray is pointy, sharp with jagged edges. They range in size from 0.18 to 2.0 m or more across in the case of the smalleye stingray and giant freshwater stingray.
The Pacific chupare or Pacific whiptail stingray is a species of stingray in the family Potamotrygonidae. It has been reported off the Pacific coast of Central America from Oaxaca, Mexico to Costa Rica, and also around the Galapagos Islands. It is usually found in shallow water on soft silty or muddy flats; it is unknown whether this species is tolerant of low salinity like the related chupare stingray. Leonard Compagno doubted the taxonomic validity of this species in his 1999 Checklist of Living Elasmobranchs.
Taeniura is a genus of stingrays in the family Dasyatidae. The species Taeniurops grabata and T. meyeni were formerly placed in this genus. However, phylogenetic research has shown that these two species are not closely related to T. lymma, and they have been assigned to a separate genus, Taeniurops.
Taeniurops is a genus of stingrays in the family Dasyatidae. Its two species were formerly contained within the genus Taeniura.
Bathytoshia is a genus of stingrays in the family Dasyatidae found worldwide in tropical and warm temperate oceans. It was formerly regarded as a junior synonym of the genus Dasyatis.
Hemitrygon is a genus of stingrays in the family Dasyatidae from marine, brackish and freshwater habitats in the central Indo-Pacific and northwest Pacific regions. The genus was formerly regarded as a junior synonym of the genus Dasyatis.
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.
Telatrygon is a genus of stingrays in the family Dasyatidae from the central Indo-Pacific. Its species were formerly contained within the genus Dasyatis.
Brevitrygon is a genus of stingrays in the family Dasyatidae from the Indo-Pacific. Its species were formerly contained within the genus Himantura.
Fluvitrygon is a genus of stingrays in the family Dasyatidae from freshwater in southeast Asia. Its species were formerly contained within the genus Himantura.
Fontitrygon is a genus of stingrays in the family Dasyatidae found in coastal tropical Atlantic waters and rivers that drain into the Atlantic. Fontitrygon species were formerly contained within the genus Dasyatis.
Maculabatis is a genus of stingrays in the family Dasyatidae from the Indo-Pacific. Its species were formerly contained within the genus Himantura.
Pateobatis is a genus of stingrays in the family Dasyatidae from the Indo-Pacific. Its species were formerly contained within the genus Himantura.
Styracura is a genus of stingray in the family Potamotrygonidae and the only genus in the subfamily Styracurinae. The two species in this genus were formerly included in Himantura, but were moved to Styracura in 2016 based on morphology and molecular evidence. Unlike other members of the family Potamotrygonidae, also known as freshwater stingrays, Styracura are found in the tropical West Atlantic and East Pacific.
The mumburarr whipray is a species of whipray from northern Australia and southern Papua New Guinea, described in 2016.
