Southern Stingray

Physical Characteristics

The Southern Stingray has a flattened, rhomboid-shaped disc, typically wider than it is long, with a pointed snout. Its dorsal surface is generally dark gray to brown or olive, often with lighter spots or reticulations, providing good camouflage against the seabed. The ventral side is whitish. It possesses a long, whip-like tail, which is at least as long as its body disc, and typically has one or more venomous, serrated spines located on the upper surface near the base of the tail.

Habitat & Distribution

The Southern Stingray is found in tropical and warm temperate waters of the Western Atlantic Ocean, ranging from New Jersey (rarely) south to Florida, the Caribbean Sea, and the Gulf of Mexico, extending down to Brazil. They prefer shallow coastal waters, typically inhabiting sandy or muddy bottoms, seagrass beds, and mangrove channels, from the surf zone down to depths of about 60 meters (200 feet). They are also commonly found in estuaries and lagoons.

Size & Weight

Typical disc width ranges from 50 to 90 cm (20 to 35 inches), with a maximum recorded disc width of up to 1.5 meters (5 feet). They can weigh up to 300 kg (660 pounds), though individuals over 100 kg are less common. The total length, including the tail, can exceed 2.5 meters (8 feet).

Similar Looking Species

The Southern Stingray can be confused with other stingray species found in the same region, such as the Atlantic Stingray (Hypanus sabinus) or the Chupare Stingray (Hypanus guttatus). The Atlantic Stingray is generally much smaller and has a more triangular disc shape. The Chupare Stingray has a more rounded disc and often lacks the prominent pointed snout of the Southern Stingray. Distinguishing features include disc shape, coloration patterns, and tail spine characteristics.

Ecological Role

Southern Stingrays are bottom feeders, playing a crucial role in the seabed ecosystem by disturbing the substrate and aerating it as they forage for prey. Their diet primarily consists of burying invertebrates such as bivalves, worms, and crustaceans, as well as small bony fish. They are preyed upon by larger sharks, such as hammerheads and tiger sharks. Their presence is an indicator of healthy shallow marine environments.
