Description:
Southern
stingrays are the largest rays along the southern U.S. coast, and can reach
6 feet in diameter across the disc. The disc is rhomboid in shape,
forming rounded corners at the tips of the pectoral fins and the front of
the snout. A ridge of low spines is present mid-dorsally and along the
shoulder area. The tail is elongate and bears a venomous spine near
the base. A cutaneous fold is present on the underside of the tail.
The pectoral fins are expanded and lie in front of the mouth, which is on
the ventral surface. No dorsal fin is present. Body color is
typically gray or brown dorsally, white ventrally. This species is
considered harmful to humans due to the venomous spine on the tail.
Though southern stingrays are generally peaceful fishes, when perturbed,
they lash at perceived attackers with the tail and can inflict painful
wounds.
Habitat:
Southern stingrays inhabit shallow coastal waters, bays, and estuaries,
typically over sandy or muddy bottoms.
Similar Species:
Small southern stingrays can be confused with a related species, the
Atlantic stingray, Dasyatis sabina. They can be distinguished
by the shapes of the snout and pectoral fins. In southern stingrays,
the snout and tips of the pectoral fins come to rounded corners. In
the Atlantic stingray, the snout is sharply pointed, while the pectoral fins
are widely rounded.
Range:
Southern stingrays range from New Jersey south to Brazil, including the Gulf
of Mexico and Caribbean. They tend to be less common north of North
Carolina.

Stingrays tend to lie partially buried in soft sand bottoms with only their
eyes visible, so are easily overlooked by swimmers and waders. The
"stingray shuffle" is recommended to prevent painful stingray
encounters. This involves shuffling rather than walking while wading.
The shuffle helps alert stingrays to the presence of waders and encourages
them to swim off. Shuffling also insures that if a wader is near a
resting ray, the ray will be lightly contacted rather than stepped on.
