Season 1

The coral reef is not only one of the most diverse communities within the animal kingdom, but also one of the fiercest, with an overwhelming number of natural predators. Dive deep with John Stoneman as he studies these marauders, from tiny slugs and coral to mighty sharks.

During World War II, nearly 100 ships, planes and submarines were sunk in Micronesian's Truk Lagoon. Many of the wrecks have now become artificial reefs, attracting a wide range of corals, fish life and interested divers like John Stoneman.

Even fish need sleep, but what happens when night falls and nocturnal predators awake? John Stoneman swims the Caribbean coral reef at night to better understand the unique balance between day and night

Many tall tales have been told about the sea, but which stories are fact and which are fiction? Join John Stoneman as he explores the Bermuda Triangle and other legends that make the Caribbean such a fascinating place.

The coral reef is the oldest ecosystem on the planet, home to more living organisms than any other habitat, including the rain forest. John Stoneman tours some of the most beautiful and prolific reefs in the world, including the Great Barrier Reef of Australia and the Red Sea Reef of Egypt and Saudi Arabia.

Follow John Stoneman as he studies some of the animals living in the sandy areas of the coral reef. Watch as the stingray feeds and some truly exotic and rarely seen creatures make themselves known.

A fascinating look at how and why ocean creatures attack others and defend themselves, and how the predatory bites and stings have been misinterpreted by humans over the years.

Water covers two-thirds of the Earth's surface, and contained therein is a vast food supply and substantial mineral resources. Oceans develop our weather systems and produce much of the oxygen we breathe, yet they are threatened by pollution and over-fishing. What can be done to same them?
