Footage shown in this television special includes the deep-sea thresher shark in the Philippines; giant whale sharks feeding off the coast of Belize; and deadly hammerheads, great whites and bronze whaler sharks in South Africa.

The Seychelle Islands, known for their long stretches of white sand, also provide a home to unusual flora and fauna, including the coco de mer, a tree with the world's largest seeds, giant tortoises inhabiting an ancient volcano and living carpets of silver lizards. This film features contributions from experts who believe these exotic species are evidence that the islands were once part of a primeval super-continent.
