Cownose Ray
Rhinoptera bonasusAlso known as Cownose Stingray
Cownose Rays are broad-winged cartilaginous fish with two rounded lobes at the front of the head and a long whip-like tail. Large schools migrate through warm western Atlantic bays and coastal waters, using plate-like teeth to crush buried shellfish.

Interaction riskVery high
- Low
- Moderate
- High
- Very high
- Why interaction risk is very high
- A stepped-on or restrained ray can drive its venomous tail spine into skin and cause a painful wound.
- Why it is dangerous
- The serrated tail spine can puncture deeply and introduce venom and tissue contamination into the wound.
- How to recognize a risky encounter
- Look for pointed wings, a notched cow-like forehead, and a long tail trailing behind the disc.
- What to do
- Never grab, pin, or lift a ray; leave the water calmly and seek urgent medical care after a spine injury.
- What to notice
- Confirm the paired rounded head lobes and broad pointed fins before recording a distant sighting.
- Support conservation
- Release only with trained fishery methods, minimize air exposure, and never retain or harass a migrating school.
Responsible observation
- Wade: Shuffle feet over sandy shallows and give passing schools an open route away.
- Boat: Slow down near surface-feeding rays and avoid cutting across tightly grouped animals.
