Where You Will See It In Cozumel

Caribbean Reef Shark is tagged on reef profiles right along the west coast, across a depth band of roughly 32 to 131 feet.

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

Deeper, and on the walls. It also shows up on Palancar Horseshoe, Punta Sur, Barracuda Reef and Chun-Chacaab.

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

A wary open-water patroller. Sightings in Cozumel are opportunistic rather than reliable, and almost always at distance on a deep southern dive.

Commonly Confused With

  • Blacktip shark — Blacktips have obvious black fin tips on top as well as underneath, and are more surface-oriented.
  • Bull shark — Bull sharks are far heavier through the body with a blunt snout; in Cozumel they are a seasonal, site-specific encounter.

Diving Etiquette And Safety

Nothing to do but hold position and watch. Do not chase for a photograph — the shark leaves and so does everyone else's sighting.
