Peppered Maskray
The peppered maskray (''Neotrygon picta'') or speckled maskray, is a species of stingray in the family Dasyatidae, found in shallow waters off northeastern Australia. This small, thin-bodied ray attains a maximum width of . It has a diamond-shaped pectoral fin disc with a row of tiny thorns along the midline, and a relatively short, whip-like tail with both upper and lower fin folds. Its upper surface has a speckled color pattern consisting of black spots and brownish reticulations on a light yellow to brown background. Favoring soft-bottomed habitats, the peppered maskray is a bottom-dwelling predator consuming mainly crustaceans (particularly caridean shrimp) and polychaete worms. It is viviparous, with litter sizes of one to three. The females supply their developing young with histotroph ("uterine milk") during gestation. Although the peppered maskray is a frequent bycatch of bottom trawl fisheries, it is still common and significant portions of its population appear to ...

Brown Whipray
The brown whipray (''Maculabatis toshi'') 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 (''H. uarnak'') and the black-spotted whipray (''H. astra''), 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 . The diet of the brown whipray consists of crustaceans and small bony fishes. Reproduction is aplacental viviparous; females produce litters of 1–2 young and supply them with histotroph ("uterine milk") during gestation. The International Union for Conservation of Nature (IUCN) has listed the brown whip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Whipray
The freshwater whipray (''Urogymnus dalyensis'') is a little-known species of stingray in the family Dasyatidae, found in a number of large rivers and associated estuaries in northern Australia. Until recently, this species was regarded as a regional subpopulation of the similar-looking but much larger giant freshwater stingray (''U. polylepsis'') of Southeast Asia. Typically reaching across, the freshwater whipray has a distinctively shaped, rounded pectoral fin disc, a projecting snout, and a thin tail without fin folds. It is plain brown above and white below with dark marginal bands. It may occasionally travel onto land and can "breathe" out of water for up to 7 minutes. The freshwater whipray is an active hunter of small fishes and shrimps, and does not currently face substantial conservation threats. Taxonomy The first known specimen of the freshwater whipray was caught during a 1989 scientific expedition from the Daly River, after which it would eventually be named. Vari ...

Black-spotted Whipray
The black-spotted whipray (''Maculabatis astra'') is a species of stingray in the family Dasyatidae, found in the coastal waters off southern New Guinea and northern Australia. Long thought to be a variant of the related brown whipray (''H. toshi''), 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 . Crustaceans are the main type of food consumed by the black-spotted whipray. It is aplacental viviparous, with females gestating 1–3 young at a time, supplying them with histotroph ("uterine milk"). Most of the black-spotted whipray's range lies within Australian waters, where it faces minimal conservation thre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thorntail Stingray
The thorntail stingray, black stingray, or longtail stingray (''Dasyatis thetidis'') is a species of stingray in the family Dasyatidae. It is found off southern Africa, Australia, and New Zealand from the intertidal zone to a depth of . This bottom-dweller inhabits soft-bottomed habitats such as lagoons, estuaries, and reefs. Growing to across and over in weight, the thorntail stingray is among the largest stingrays in the world. Uniformly dark above and light below, it has a diamond-shaped pectoral fin disc and a very long, whip-like tail with a fin fold underneath. The upper surface of the disc and the tail bear numerous stout, sharp thorns. The diet of the thorntail stingray consists of benthic invertebrates and bony fishes. It has been known to gather in large groups during summertime. Like other stingrays, it is aplacental viviparous, with the developing embryos sustained to term by histotroph ("uterine milk") produced by the mother. The venomous stinging spine of the tho ...

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 thei ...

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 synonymi ...

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 ...
