Splendid toadfish (endemic to Cozumel and nowhere else), eagle rays, turtles, and huge barrel sponges. Cousteau's 1961 television film on Cozumel effectively created Caribbean dive tourism. The island's reefs sit in the Mesoamerican Barrier Reef, the second-largest reef system on earth, and were made a national marine park in 1996. Anchorage: Marine park, moorings only, no anchoring on reef. Cozumel and Puerto Aventuras marinas. Hazards: No site-specific hazards noted, brief normally. Más
