The short-tail stingray or smooth stingray is a common species of stingray in the family Dasyatidae. It occurs off southern Africa, typically offshore at a depth of 180–480 m (590–1,570 ft), and off southern Australia and New Zealand, from the intertidal zone to a depth of 156 m (512 ft). It is mostly bottom-dwelling in nature and can be found across a range of habitats from estuaries to reefs, but also frequently will swim into open water. One of the largest stingrays in the world, this heavy-bodied species can grow upwards of 2.1 m (6.9 ft) across and 350 kg (770 lb) in weight. Its plain-colored, diamond-shaped pectoral fin disc is characterized by a lack of dermal denticles even in adults, and white pores beside the head on either side. The body can have colors as well as dark grey or black with rows of white spots along each wing. Its tail is usually shorter than the disc and thick at the base. It is armed with large tubercles and a midline row of large thorns in front of the stinging spine which has the dorsal and ventral fin folds behind.
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.
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.
Urogymnus is a genus of stingrays in the family Dasyatidae from marine, brackish and freshwater habitats in the Indo-Pacific and tropical East Atlantic regions. The genus was previously considered to be monotypic, containing only the porcupine ray. Molecular phylogenetic research published in 2016 reassigned several species from Himantura to Urogymnus.
The broad stingray, also known as the brown stingray or Hawaiian stingray, is a species of stingray in the family Dasyatidae. They range across the Indo-Pacific from southern Africa to Hawaii, and are the predominant species of stingray in the inshore waters of the Hawaiian Islands. This benthic fish also inhabits sandy or muddy flats at depths greater than 15 m (49 ft) in the Eastern Atlantic, from southern France to Angola, including the Mediterranean Sea. Usually growing to 1 m (3 ft) across, the broad stingray has a wide, diamond-shaped pectoral fin disc with a protruding snout tip and a long tail with a ventral fin fold. At night, this species actively forages for bottom-dwelling invertebrates and bony fishes, often near the boundaries of reefs. Reproduction is aplacental viviparous. As substantial threats to its population exist in many areas of its wide distribution, IUCN has listed this species as Vulnerable.
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 roughtail stingray is a species of stingray in the family Dasyatidae, with separate populations in coastal waters of the northwestern and southwestern Atlantic Ocean. This bottom-dwelling species typically inhabits sandy or muddy areas with patches of invertebrate cover, at a depth of 15–50 m (49–164 ft). It is seasonally migratory, overwintering in offshore waters and moving into coastal habitats for summer. The largest whip-tail stingray in the Atlantic, the roughtail stingray grows up to 2.6 m (8.5 ft) across and 360 kg (800 lb) in weight. It is plain in color, with an angular, diamond-shaped pectoral fin disc and a long, whip-like tail bearing a subtle fin fold underneath. The many thorns on its back and tail serve to distinguish it from other stingrays that share its range.
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.
The pitted stingray is a species of stingray in the family Dasyatidae, endemic to the waters around Japan and the Sea of Japan. It typically found near the coast at depths of 40–60 m (130–200 ft), but may also venture into the open sea. Measuring up to 2 m (6.6 ft) across, the pitted stingray has a diamond-shaped pectoral fin disc with a characteristic W-shaped groove on the underside. The total length including the tail has a record of 2.8 m (9.2 ft). Other identifying characteristics of this species include its dark gray dorsal coloration with small white spots, and the presence of dorsal tubercles in adults. Pitted stingrays are caught as bycatch in coastal fisheries and brought to market. The International Union for Conservation of Nature (IUCN) does not yet have sufficient data to assess this species beyond Data Deficient. This species is now regarded as a population of the Short-tail stingray.
Taeniurops is a genus of stingrays in the family Dasyatidae. Its two species were formerly contained within the genus Taeniura.
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.

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.
