Where You Will See It In Cozumel

Southern Stingray is tagged on reef profiles right along the west coast, across a depth band of roughly 6 to 98 feet.

On an ordinary beginner boat dive. It is recorded at La Francesa and Palancar Gardens. No advanced certification needed.

Deeper, and on the walls. It also shows up on Palancar Bricks and Paso del Cedral.

Conditions change the odds more than the site does — the current, the time of day and how much the group has already stirred up the sand. Ask your guide what they have been seeing that week.

Behaviour

Feeds by blowing water into the sand to expose buried molluscs and worms. Buries itself to rest and to ambush, which is why almost all injuries happen to people walking on sand rather than to divers.

Commonly Confused With

  • Yellow stingray — The yellow stingray is much smaller with a dense pattern of yellow-brown spots and a rounder disc.
  • Spotted eagle ray — Eagle rays swim in open water with white spots on a dark back and never lie buried.

Diving Etiquette And Safety

Never step down onto sand — shuffle. The barb is a defensive tail-flick, used only when the animal is trodden on or pinned.
