dasyatidae common name

1994. Stingrays of the subfamily Potamotrygonidae (river stingrays) tend to be smaller, usually less than 30 cm in diameter and less than 1 m long, although a few may attain 2 m. A unique aspect of river stingrays is their chemical adaptation to fresh water; their blood contains very low concentrations of urea, and their rectal gland (used by fishes for salt secretion) is reduced. (Allen, 1996; Böhlke and Chaplin, 1968; Hamlett and Koob, 1999; Helfman, et al., 1997; Last and Stevens, 1994; Moyle and Cech, 2000; Wheeler, 1985). Pp. At least one species, Taeniura lymma, moves in large numbers into shallow sandy areas along the Australian coast during high tide, and at low tide retreats to caves and ledges for shelter. 398-443 in W Hamlett, ed. uses smells or other chemicals to communicate. Stingrays tend to have drab coloration, but river stingrays in particular often have various patterns and markings over the brown or gray background. Fishes of the World – third edition. Most stingrays are benthic, burying themselves partially under sand or mud in relatively shallow water.

Because they depend on symbiotic photosynthetic algae, zooxanthellae, they cannot live where light does not penetrate. Reportedly, soaking the injured part of the body in hot water (about 50 degrees Celsius) for 30 to 90 minutes can alleviate pain from the venom. Accessed The polyps live only on the reef surface. Common name: Izu stingray Original description species: (NISHIDA & NAKAYA, 1988) Genus: Hemitrygon MÜLLER & HENLE, 1838 Family: Dasyatidae JORDAN & GILBERT, 1879 Order: Myliobatiformes Superorder: Batomorphii Subcohort: Neoselachii … Common name: Stingrays Silhouette. Some large rays are a popular part of public aquarium exhibits. 1998. Dasyatidae. Once sexually mature, stingrays have only one litter per year, usually bearing two to six young. The great hammerhead Sphyrna mokarran, in particular, appears to specialize in eating stingrays. 1968. (Helfman, et al., 1997), Stingrays are nearly cosmopolitan in tropical and warm temperate seas, and therefore are a consistent predator on populations of mollusks, crustaceans, worms, and fishes. Classification, To cite this page: Found on sandy bottoms, seagrass beds, lagoons and the reef face (Ref. The name pastinaca dates from the time of the Romans, since the sting for them had resemblance to the root of the parsnip (Pastinaca sativa). Rays are considered food fish in Australia, Europe, and parts of Asia, and in some places are among the most highly priced fishes. Allen, G., D. Robertson.

(Helfman, et al., 1997; Last and Stevens, 1994), Cartilaginous fishes in general are important to humans in a number of ways. 60-69 in W Eschmeyer, J Paxton, eds. In other languages, common names include arraia-manteiga (Portuguese), manteiga (Portuguese), raia (Portuguese), or raia amarela (Portuguese); stumpfnasenstechrochen (German); stompsnuitpijlstaartrog (Dutch); and raya mediana (Spanish), raya hocicona (Spanish), and raya (Spanish). Stingrays and river rays frequently bury themselves in the sand or mud in shallow water, which makes it probable that waders will step on them. Fishing is the way of life of most of costal community. For some, turbulent coastal surf provides a constant flow of invertebrates. New data on the reproductive biology of the thorny stingray, Dasyatis centroura (Pisces: Dasyatidae) from off the Tunisian coasts. In at least one species, Dasyatis centraura, females are reported to be larger than males. body of water between the southern ocean (above 60 degrees south latitude), Australia, Asia, and the western hemisphere. Medium to large-sized rays with the tail longer than the disc and one or more venomous barbs on a long slender tail. Since their mouths are directed downward and often placed against the sand, stingrays use their spiracles rather than their mouths for water intake, and, if the gills are covered with sand, the spiracles are also used for expelling water. Their mouths, which contain fleshy papillae on the floor, are small and located under the end of the snout. The family Dasyatidae includes stingrays, or whiprays, and river stingrays, encompassing nine genera and about 70 species. They can, however, swim powerfully; some migrate seasonally as far north as the British Isles, and at least one species, the pelagic stingray lives swimming freely in the water column. As part of our continual effort to improve user experience, we have been working with our Partners to standardize the display of species’ common names across our Data Warehouse and SAFIS applications. At birth the ray is fully developed and looks like a small adult. Fishes of the Bahamas and Adjacent Tropical Waters. Like shark fins, fins of some rays are harvested in Asia for soup and as an aphrodisiac. English language common names for Dasyatis kuhlii include bluespotted stingray, blue-spotted stingray, blue-spotted maskray, blue-spotted stingaree, blue-spotted stingray, and Kuhl’s stingray. 1479-1505 in Carpenter, K.E. The color of Dasyatis americana, for example, varies depending on the color of the surface on which it lies. Common Stingray – Dasyatis pastinaca The Common Stingray is a species in the family of the Dasyatidae (Whiptail Stingrays) and thus belongs to the subclass of the Elasmobranchii. Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. islands that are not part of continental shelf areas, they are not, and have never been, connected to a continental land mass, most typically these are volcanic islands. The most well known negative impact of stingrays is the excruciatingly painful sting they can inflict. and across multiple seasons (or other periods hospitable to reproduction). Rays also belong to a group of fishes, the elasmobranchs, whose electrical sensitivity seems to exceed that of all other animals. Other common names include banana-tail ray, drab stingray, fantail ray, feathertail stingray, and frill tailed sting ray. Elasmobranch fishes have relatively complex endocrine (hormonal) systems; based on knowledge of other vertebrates with similar systems, it is likely that females signal to males through chemical or behavioral cues to indicate when their hormonal state is appropriate for mating. In lab experiments, stingrays changed their feeding location according to artificially induced changes in the electrical field around them. Jonna, R. 2003. Like other rays, they have enlarged pectoral fins that form a disc. 50449).Distinct pairing with embrace (Ref. (Allen, 1996; Froese, et al., 2003; Last and Stevens, 1994; Wheeler, 1985), Some stingrays, like Dasyatis fluviorum, wreak havoc with oyster farms and cultivated clam beds. No. Male Reproductive System. Common carp Cyprinus carpio Cyprinidae - carps . Australian Aborigines have eaten rays for centuries. Allen, T. 1996. Rays that have two spines, however, are considered inedible. Dordrecht, The Netherlands: Kluwer Academic Publishers. 114953). Like other rays, stingrays have a spiral valve in their intestine that increases food absorption, and lack a swim bladder. In otherwords, Europe and Asia and northern Africa. This reproductive strategy renders them potentially vulnerable to human activity. Gestation may take up to 12 months. see also oceanic vent. There are currently FIVE members of the Whiptail Stingray Angelfish or Dasyatidae Family, two from the Atlantic, two from the Pacific Ocean, and one from both the Atlantic and Pacific Oceans, presented in this website:. 1997.

They lie buried in sand or mud in backwaters and shallows of rivers. They do not appear in all South American Atlantic-draining river systems, however, and some, like Potamotrygon leopoldi, are only found in a single river. In this system, called aplacental uterine viviparity, developing embryos receive most of their nutriment from a milky, organically rich substance secreted by the mother’s uterine lining. (Allen and Robertson, 1994; Wheeler, 1985), Dasyatinae is primarily a marine subfamily, although some members live in brackish or fresh water. a substance used for the diagnosis, cure, mitigation, treatment, or prevention of disease, animals which must use heat acquired from the environment and behavioral adaptations to regulate body temperature. (Allen, 1996; Bleckmann and Hofmann, 1999; Helfman, et al., 1997), Stingrays feed on mollusks, worms, crustaceans, fishes, clams, crabs, and shrimps. The cowtail stingray is a species of stingray in the family Dasyatidae, widespread in the Indo-Pacific region and occasionally entering freshwater habitats. uBio is a networked information service for biological information resources. 1-42 in W Hamlett, ed.

Living in Australia, New Zealand, Tasmania, New Guinea and associated islands. In the English language, Dasyatis say is usually referred to as the bluntnose stingrayor Say’s stingray. Taxon Information Upper Saddle River, NJ: Prentice-Hall. 45335). They grow and mature slowly, and the size of the adult population closely determines the number of young produced, due to their “slow” reproductive strategy of investing a great deal of energy in relatively few young over a lifetime. at http://www.fishbase.org/.

Hamlett, W., T. Koob. It uses its hammer head to knock a ray to the bottom, and then pins the ray, once again with its head, pivoting around to bite the ray’s disc until the ray succumbs and can be eaten. They are most common in shallow tropical waters but can be found in temperate regions as well. FAO Species Identification Guide for Fisheries Purposes.

The serrated, barbed spine not only delivers venom, but also creates a deep wound often worsened by the thrashing of the ray. living in sub-Saharan Africa (south of 30 degrees north) and Madagascar. Others venture into the open ocean, with one species, the pelagic stingray, living entirely in the open ocean, away from the bottom. Like all rays, they have ventral gill openings. makes seasonal movements between breeding and wintering grounds, eats mollusks, members of Phylum Mollusca. offspring are produced in more than one group (litters, clutches, etc.) Capape, C. 1993.

Moyle, P., J. Cech. Since few young are produced, it is important that they survive, and to this end rays are born at a large size, able to feed and fend for themselves much like an adult. The fam­ily Dasy­ati­dae in­cludes stingrays, or whiprays, and river stingrays, en­com­pass­ing nine gen­era and about 70 species. Researchers have found that in some stingrays, the stomach and spiral intestine are among the first organs to develop and function, so that the embryo can digest the uterine “milk.” Rays’ eggs are small and insufficient to support the embryos until they are born, although the first stage of development does happen inside tertiary egg envelopes that enclose each egg along with egg jelly. Last, P.R. In some groups the epithelium, or wall, of the uterus has evolved to form trophonemata, elongated villi that extend into the uterine cavity to provide greater surface area for respiratory exchange and histotroph excretion. (Last and Stevens, 1994; Moyle and Cech, 2000), Marine stingrays of the subfamily Dasyatinae spend much of the time partially buried under sand or mud in warm shallow areas. Rome : FAO Vol. Victims of stings generally recover, but fatalities have occurred. It typically inhabits sandy or muddy habitats in coastal waters shallower than 60 m (200 ft), often burying itself in sediment. | ITIS | CoL | WoRMS | Cloffa Elasmobranchii (sharks and rays) > Myliobatiformes (Stingrays) > Dasyatidae (Stingrays) > Urogymninae Etymology: Himantura: Greek, iman, imantos = thong, strap + Greek, oura = tail (Ref.

Development in the uterus usually takes about two to four months. Likewise, sting-bearing young are able to pass out of the mother’s body without stinging her because their stings are encased in a pliable sheath that sloughs off after birth. This group was the first to bear live young, nourish developing embryos by means of a placenta, and to regulate reproduction and embryonic growth hormonally. (Allen and Robertson, 1994; Böhlke and Chaplin, 1968; Last and Stevens, 1994; Moyle and Cech, 2000; Wheeler, 1985), Although rays can grow very large, they are still preyed upon by other large fishes, especially sharks. The young are usually born in February, but the duration of pregnancy depends on the specific geographic region and altitude. In other words, Central and South America. 3168). : American Fisheries Society Special Publication, no. Family Dasyatidae. (Hamlett and Koob, 1999; Hamlett, 1999; Wourms and Demski, 1993), Rays bear young on a yearly cycle, although pregnancy usually lasts only several months, generally spanning some period in the spring, summer, and fall. The Animal Diversity Web is an educational resource written largely by and for college students. Fishes of the Tropical Eastern Pacific. The Living Marine Resources of the Western Central Pacific. The stingrays are a family-Dasyatidae-of rays, cartilaginous fishes related to sharks. In addition to their defensive venomous sting, most stingrays have drab coloring that blends in with the sand or mud bottom. having markings, coloration, shapes, or other features that cause an animal to be camouflaged in its natural environment; being difficult to see or otherwise detect. Synapomorphy of the Bilateria. The dasyatid stingrays, also called whip-tailed rays and stingarees, inhabit all oceans and certain South American rivers. (Allen and Robertson, 1994; Böhlke and Chaplin, 1968; Froese, et al., 2003; Helfman, et al., 1997; Last and Stevens, 1994; Last and Stevens, 1998; Moyle and Cech, 2000; Nelson, 1994; Wheeler, 1985), Stingrays of the family Dasyatidae have expanded pectoral fins that form a circular, oval, or rhomboidal disc. Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0.Distinguished from the other stingray species in the Mekong basin by the presence of a ventral and a dorsal skin folds on the tail and the bright orange color of the ventral surface of the disc. An aquatic biome consisting of the open ocean, far from land, does not include sea bottom (benthic zone). However, stingrays have a system that involves internal fertilization, so it can logically be inferred that mating communication between male and female must happen to an extent that allows the male to insert at least one of his two claspers (male reproductive organs that are modifications of the pelvic fins) into the female’s cloaca to deposit sperm. 1985. having body symmetry such that the animal can be divided in one plane into two mirror-image halves. River rays (subfamily Potamotrygoninae) begin breeding in September or October. Stingrays can be found in all tropical and subtropical seas. Along with eagle rays (Myliobatidae), stingrays reportedly have the most complex brains of all elasmobranch fishes. Martin F. Gomon & Dianne J.
