Bluntnose Stingray

Hypanus say

The Bluntnose Stingray is a graceful, bottom-dwelling navigator of our coastal shorelines. With its distinctive rounded wings and subtle camouflage, it turns the sandy seafloor into a hidden world of activity.

Behavior

The Bluntnose Stingray is a master of camouflage that spends much of its life on the seafloor. It often buries itself in the sand or mud, using its pectoral fins to stir up sediment that then settles over its body. This behavior, known as 'settling,' leaves only the eyes and spiracles (breathing holes) visible, allowing the ray to remain undetected by predators like sharks while it waits for prey to pass by.

While generally solitary, these rays are known to migrate in large groups in the northern parts of their range, moving toward warmer southern waters as temperatures drop in the fall. They are not aggressive by nature, but they are equipped with a venomous, serrated spine at the base of the tail for self-defense. Most interactions with humans occur when a ray is accidentally stepped on in shallow water, highlighting the importance of the 'stingray shuffle' when wading.

Camera Tips

To capture high-quality footage of a Bluntnose Stingray, you will need a waterproof action camera or a specialized underwater housing. Because these rays stay low to the ground, the most effective setup involves mounting your camera on a weighted base or a 'sand-anchor' tripod only a few inches above the seafloor. Aim the lens horizontally across a sandy clearing near an estuary edge or a salt marsh creek, as these are primary hunting grounds for the species.

Baiting is highly effective for drawing these rays into your camera's field of view. Use a mesh bag or a perforated PVC tube filled with crushed blue crab, shrimp, or oily fish scraps. Secure the bait about 3 to 5 feet in front of the lens. The ray’s keen electroreceptors and sense of smell will lead it to the source, often resulting in fascinating footage of the ray 'tenting' its body over the bait to suction up the food.

Timing is critical when setting your camera in tidal areas. Position your gear during low tide in spots where you see 'feeding pits'—circular depressions in the sand left by rays searching for clams. Ensure your camera is active during the incoming tide, as rays move into the shallows with the rising water to forage. Using a wide-angle lens is recommended to capture the full span of their rhomboid wings as they glide past the camera.

Frequently Asked Questions

Bluntnose Stingrays are primarily crepuscular, meaning they are most active during the low-light hours of dawn and dusk, though they are known to forage throughout the night using their electroreceptive senses.

If your 'backyard' is on a saltwater canal or estuary, you can attract them by providing a clear sandy bottom area and using a scent-based lure like a chum bag filled with crushed crustaceans or oily fish.

Their diet consists mainly of benthic invertebrates, including crabs, shrimp, clams, and worms, which they uncover by flapping their wings against the sand or using suction.

Yes, they are very common in suburban coastal areas, especially in shallow lagoons, tidal creeks, and near fishing piers from Massachusetts down to Florida and the Gulf Coast.

The Bluntnose Stingray has a blunt, rounded snout and rounded wing-tips, whereas the Atlantic Stingray has a much more pointed, elongated snout and a smaller overall body size.
