This species bears witness to an evolutionary bifurcation 380 million years ago, and bears the marks of a great event: the day the fish left the ocean for the open air. Does it hold the secret to the transition to walking on land? In 2010, a marine biologist and outstanding diver, Laurent Ballesta, took the first photographs of the Coelacanth in its ecosystem. In April 2013, divers and researchers set down their equipment at the Sodwana base camp in South Africa, in the club founded by Peter Timm (who died in 2014). Six weeks of extreme diving at depths of over 120 meters, in an attempt to film the Coelacanth with a double-headed camera, collect its DNA and tag a subject with a satellite-linked beacon...
