What is the stingray with pointy wings long pointy tip?

The stingray you’re describing is likely the "thorny stingray" (Dasyatis centroura), known for its elongated, pointed wings and long, tapering snout. This species is characterized by its flattened body and thorn-like spines along its back, which provide protection from predators. Thorny stingrays are typically found in coastal waters and can bury themselves in the sand to camouflage from threats. Their unique shape allows them to navigate their environment effectively while hunting for prey.
