The Blue Stingray (Dasyatis chrysonota) is a species of ray in the family Dasyatidae. It is a common inhabitant of the western Atlantic Ocean and the Gulf of Mexico, known for its striking blue coloration and powerful sting. The species is characterized by its relatively small size and its preference for sandy and muddy bottoms, where it can be found at depths ranging from 1 to 110 meters.
Description & Characteristics
The Blue Stingray (Dasyatis chrysonota) is a distinctive species with a flattened, diamond-shaped body. Its upper surface is a striking bright blue, often with darker spots or blotches, while the underside is typically white. The species is relatively small compared to other stingrays, with an average maximum size of 75 centimeters (30 inches).

They are typically found in areas with sandy or muddy bottoms, where they can burrow into the sediment to ambush prey or avoid predators. The species is known to inhabit both shallow and deeper waters, with a depth range of 1 to 110 meters. This broad depth range suggests that the Blue Stingray (Dasyatis chrysonota) can adapt to different environments, making it a prevalent presence in both coastal and offshore areas.
