Maculabatis is a genus of stingrays in the family Dasyatidae from the Indo-Pacific. Its species were formerly contained within the genus Himantura . [1]
The genus contains two groups, the "gerrardi-complex" containing spotted species and the "pastinacoides-complex" containing plain species.
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 whitespotted whipray or sharpnose stingray is a species of stingray in the family Dasyatidae. It is found in coastal regions including estuaries, in the Indo-Pacific, and has also been recorded in the Ganges River. It reaches a maximum length of 2 metres. As presently defined, it is probably a species complex.
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. They range in size from 0.18 to 2.0 m or more across.
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 tubemouth whipray is a little-known species of stingray in the family Dasyatidae, named for its distinctive, highly protrusible jaws. It is found in shallow, brackish water near mangrove forests and large river mouths along the coasts of southwestern Borneo and southern Sumatra. Measuring up to 1 m (3.3 ft) across, this species has a diamond-shaped pectoral fin disc with an elongated, pointed snout and broadly rounded outer corners. The upper surface of the disc is a plain grayish or brownish in color, and covered by small, flattened dermal denticles. The tubemouth whipray is relatively common at present, but is heavily pressured by habitat degradation and coastal fisheries. The International Union for Conservation of Nature (IUCN) has listed it as Vulnerable.
The Hortle's whipray is a little-known species of stingray in the family Dasyatidae, occurring in shallow estuaries and mud flats off southern New Guinea. This species, growing to 71 cm (28 in) across, has a heart-shaped pectoral fin disc with a long, pointed snout and minute eyes. It has a wide dorsal band of dermal denticles extending from in front of the eyes to the tail, as well as scattered sharp denticles on the snout. The underside of the disc is a distinctive bright yellow in color, sometimes with darker markings around the nostrils, mouth, and gill slits. The Hortle's whipray is threatened by extensive seine fisheries and habitat degradation, leading the International Union for Conservation of Nature (IUCN) to assess it as Vulnerable.
The black-spotted whipray is a species of stingray in the family Dasyatidae, found in coastal waters off southern New Guinea and northern Australia. Long thought to be a variant of the related brown whipray, this species has an angular, diamond-shaped pectoral fin disc and a whip-like tail without fin folds. It is characterized by its dorsal color pattern, which consists of a variably extensive covering of small, close-set dark, and sometimes also white, spots on a grayish brown background. In addition, the tail has alternating light and dark saddles past the stinging spine. This species reaches a maximum recorded width of 80 cm (31 in).
The brown whipray is a species of stingray in the family Dasyatidae, common in inshore, muddy habitats along the northern coast of Australia. It has often been confused in literature for the honeycomb stingray and the black-spotted whipray, which until recently was thought to be the same species. This species has an angular, diamond-shaped pectoral fin disc and a long, very thin tail without fin folds. It is plain brown above, sometimes with white dots or flecks near the edge of the disc, and white below; the tail is dark all over, with alternating dark and light bands near the tip. The maximum recorded disc width is 74 cm (29 in).
The honeycomb whipray is a species of stingray in the family Dasyatidae, found widely in the shallow coastal waters of the Indo-Pacific from India to the Malay Archipelago. This large species grows to 1.3 m (4.3 ft) across and has a diamond-shaped disc with rounded corners and a projecting, pointed snout. Its tail is long and whip-like, without fin folds. Adults have a striking dorsal color pattern consisting of large, dark brown rings and reticulations delineated by thin yellow lines, while juveniles have a pattern of large dark spots. This ray can also be distinguished from its similar relatives by an enlarged, pearl-like dermal denticle at the center of the back, which is followed by a few thorns. The International Union for Conservation of Nature (IUCN) has assessed the honeycomb whipray as Vulnerable, as it faces heavy fishing pressure and habitat degradation across much of its range.
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.
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.
