In November 2000, South-African divers using mixed gas tanks dived in an underwater canyon at Sodwana Bay on the south coast of South Africa. This is the most modern form of deep sea diving. They followed the traces of a South-African legend, the coelocanth, a 400 million year-old fish which in 1938, by pure chance, got trapped in the net of a Trawler in East London. At the time, this was one of the most important zoological scientific adventures of the century. A fish dating from the earliest pre-history of all land-living four-legged vertebrates, which had been doomed to be extinguished, had somehow managed to survive in a hidden niche of the Indian Ocean. On that November day in 2000, the Sodwana divers succeeded in something which had seemed impossible until then. After two years of arduous research, a diver discovered the first living coelocanth - in a depth of only 109 metres.
