How to Identify Atlantic Stingray

To identify Atlantic Stingray (Dasyatis sabina), look at these key features.

Physical Characteristics

Body shape

flat

Coloration

Dorsal surface typically light brown, olive, or grayish, often with darker spots or mottling. Ventral surface is white or off-white. Some individuals may exhibit a yellowish or reddish tint.

Scale type

none

Mouth position

inferior

Distinctive features

Diamond-shaped disc, slightly wider than long., Snout is short and bluntly pointed., Eyes are small and located on top of the head, followed by spiracles., Tail is relatively short, typically less than twice the disc length, and bears a single, prominent, serrated venomous spine, usually located about halfway down the tail., No dorsal fin. A small caudal fin fold may be present on the ventral side of the tail tip., Skin is smooth, lacking dermal denticles over most of the disc, though some small denticles may be present along the midline in larger individuals.

Dorsal fin

Absent

Tail fin

Short, whip-like, with a venomous spine and sometimes a small ventral fin fold near the tip.

Pectoral fin

Large, forming the 'wings' of the disc.

Distinctive fins

No distinct pelvic fins separate from the disc margin; they are small and located at the base of the tail.

Identification Tips

1. 1

   Disc Shape

   Look for a diamond-shaped disc that is slightly wider than it is long, with a short, blunt snout.

2. 2

   Tail Length and Spine

   The tail is relatively short, usually less than twice the disc length, and possesses a single, prominent, serrated venomous spine located about halfway down the tail. This distinguishes it from other stingrays with longer tails or multiple spines.

3. 3

   Coloration

   Dorsal coloration is typically light brown, olive, or grayish, often with subtle darker markings. The ventral side is white.

4. 4

   Habitat

   Its presence in brackish or freshwater environments is a strong indicator, as few other stingray species tolerate such a wide range of salinities.
