RAISE AWARENESS, TRANSMIT OUR PASSION, HELP PROTECT THE OCEAN.
Last April 5th, globally renowned diver and naturalist Laurent Ballesta, equipped with a Blancpain Fifty Fathoms timepiece on his wrist and accompanied by specially trained divers and researchers from the South African Institute for Aquatic Biodiversity SAIAB, together with ten scientists from the Museum of National History and from CNRS, the French National Research Institute, all left for South Africa to undergo 40 days of deep water diving to meet with legendary bottom-dwelling sea creature, the coelacanth.
Locally known as Gombessa, this peaceful giant measures two metres long and was once thought to have become extinct 70 million years ago. However, this rare fish, when discovered alive in 1938 has come to represent one of the most important zoological discoveries of the 20th century:
- it is seen as the ‘transition animal’ from backboned fish to the earliest four-legged vertebrate land animals; and
- with its lobe fins and ‘primitive lung’, this fish bears testament to our forays within theprimordial soup, 379 million years ago.
For over a century, the coelacanth has sparked intense debate between scientists and creationists. Portrayed as the crucial link between fish and land animals, it is without doubt one of the most hotly dissected and debated creatures of our time, and yet we know almost nothing about its way of life. Extremely rare and living over 100 metres deep, very few direct sightings have been witnessed until now. The GOMBESSA expedition, the result of two years’ scientific research, logistical and human preparedness, for the first time enabled observations and scientific experiments to be carried out in contact with a living coelacanth.
To reach this living legend, Laurent Ballesta and his team of divers had to perform daily deep water dives to Jesser Canyon caves, 120 metres below the surface: a depth where each minute passed underwater is paid for in long hours of decompression.
Once in contact with the animal, they implemented scientific protocol devised by the research team from the National History Museum and from CNRS, led by Professor Gaël Clément, palaeontologist at the Museum, and by South African biologists, Kerry Sink and Angus Paterson from SAIAB.
