A gruelling circumnavigation of the globe, taking in the greatest thrills and spills of the world's oceans. During the course of this expedition, the team will dive with spotted dolphins, great whites, cape fur seals, sea lions, grey, white tip and nurse sharks, eagle, golden, sting and manta rays. They'll explore caves, caverns, coral reefs and giant drop offs.

The expedition starts in Cape Town, diving with great white sharks. Next stop is Aliwal Shoal in Natal, home of the ragged tooth shark and humpback whales passing through on their annual migration. Then onto Lake Malawi, one of Africa's great freshwater wildernesses, before crossing the world to Palau in Micronesia, home of Blue Corner, reef sharks, wrecks and caverns. From there it is a short hop to Yap, manta ray heaven.

From Yap the team move onto the Great Barrier Reef, before flying onto the Poor Knights Islands in New Zealand. Then it's across the Pacific to the Galapagos before flying to Belize. The last leg of the expedition takes the team to the Little Bahamas banks, and the opportunity to dive with completely wild spotted dolphins.
