They average 24 inches, and weigh around 11lbs. margaritella). Some larger females also develop tubercles around the eyes and spiracles.

It has a flat, diamond-shaped disc, with a mud brown, olive, and grey dorsal surface and white underbelly (ventral surface).

Dorsal and ventral fin folds are present on the tail.

Humans are also considered a danger to the Atlantic Stingray. Brian Mitchell with MBFD said the department has used four stingray kits since the end of May to treat symptoms or wounds similar to a stingray envenomation.

Exclusive Grand Strand neighborhood the Grand Dunes in midst of war between Golf Village Property Owners’ Association and new homeowner over roof design. “Stingray stings are fairly common across the coast during swimming season, and while they can be extremely painful, with proper treatment they do not typically cause long-term complications,” S.C. Department of Natural Resources media coordinator Erin Weeks told The Sun News.

The greatest danger, however, is from infection. [2], Despite having a regular freshwater presence, the Atlantic stingray is physiologically euryhaline and no population has evolved the specialized osmoregulatory mechanisms found in the river stingrays of the family Potamotrygonidae. The southern stingray (Hypanus americanus) is a whiptail stingray found in tropical and subtropical waters of the Western Atlantic Ocean from New Jersey to southern Brazil. The kits allow officials to remotely heat water in order to immerse the affected area in hot water, which provides significant and rapid pain relief, he said. Its distinguishing is its elongated snout.

The embryos are sustained by a yolk sac until around day 60, after which they are nourished by uterine milk secreted by the mother (histotrophy).

The stinger, or spine near the base of the tail, is hard and sharp with backward pointing barbs (retroserrations) that can cause a jagged cut. However, the osmotic pressure between their internal fluids and external environment still causes water to diffuse into their bodies, and they must produce large quantities of dilute urine (at 10 times the rate of marine individuals) to compensate. 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. [7] The stingrays in the St. Johns River system represent the only permanent freshwater elasmobranch population in North America. Courtship involves the male following the female and biting at her body and fins, and the male will grip onto the female's pectoral fin to assist in copulation.

In freshwater, the American Alligator is the major predator of the stingray.

Marine males mature at a disk width of 20 cm (7.9 in) and females at a disk width of 24 cm (9.4 in). It may be distinguished from other stingrays in the area by its relatively elongated snout. [8], Like other stingrays, the Atlantic stingray is viviparous.

A lifeguard on the scene said the victim was stung in the leg while swashing in shallow waters. The tail is long and whip-like, with a serrated spine measuring a quarter of the width of the disk. Description The Atlantic Stingray (Hypanus Sabina) is a species of stingray common along the Atlantic coast of North America from Chesapeake Bay to Mexico, including brackish and freshwater habitats. Injuries are common among surf fishermen in southern waters who accidentally step on the animals. When feeding, these rays will position themselves facing the current so that the sediment will be washed away. Despite an encounter with a stingray being purely accidental, those who are stung should immediately seek medical treatment to ensure the barb is safely removed or apply very hot water to the wound to ease the pain while awaiting medical care.

According to representatives with SCDNR, the state is home to a number of stingray species; some with stingers, or barbs, and some without.

During the reproductive season, the teeth of mature males change to feature long, sharp cusps that curve towards the corners of the mouth, for gripping onto females during mating. The coloration is brown or yellowish brown above, becoming lighter towards the margin of the disk and sometimes with a dark stripe along the midline, and white or light gray below.

The Atlantic stingray is capable of tolerating varying salinities and can enter freshwater; it has been reported from the Mississippi River, Lake Pontchartrain, and the St. Johns River in Florida.
