Reef Wrecks: Series 1
The ocean floor is home to centuries’ worth of sunken vessels integrated into marine habitats. Explore extraordinary wrecks around the world and learn how these artificial structures have become a part of the ecosystem–and in some cases, a vital tool in reversing the effects of human impact.

Part 5: Mexico’s Artificial Reefs
Shy sweepers, territorial grouper, and the worlds largest fish, the whale shark, all have one thing in common: They love a good shipwreck. Explore the sunken ships off the Yucatan Peninsula as they slowly transform into coral reefs, becoming a surprising and much-needed source of food and shelter.
