South Africa: Expedition to study fossils

Scientists are launching a major study of "living fossils" in deep waters off South Africa with the help of a small submersible craft that can probe to depths of 1,300 feet. It is hoped that the minisub, which can fit only two people, will shed light on the elusive coelacanth, a curious looking fish that has been swimming the seas for an astonishing 400 million years.
