Lilian Charistoi, an underwater photographer and videographer, observed a flock of bottlenose dolphins off the coast of the Basques on April 25 in Gouf de Cabreton. Passionate about diving, this native of Bayonne has just published a book that reveals the incredible richness of this underwater canyon, reaching depths of up to 4,500 meters.
The scene was filmed just 7 kilometers from the Basque coast, in an area where the ocean is still agitated by the waters of the Adour. Beneath the surface lies the spectacular underwater canyon Gouf de Capbreton.
Lilian Charistoi, an underwater photographer and videographer based in Bayonne, spotted a group of bottlenose dolphins there.
Unlike common dolphins, which usually swim in the open sea, this species, called Tursiops, feeds near the coast. These dolphins find big fish there (mackerel, mullet, etc.), which they love.
An encounter that needs to be able to provoke without disturbing the life of the animalexplains Lillian, who has been accustomed to observing marine life for more than 20 years in the world.
In particular, that day he noticed a mother and her child, never moving away from each other.

Lillian has been observing the species living there or passing through the area for years. Thus, among them are dolphins, as well as bluefin tuna, killer whales, sperm whales, whales, jellyfish … There are also subtropical species in late summer and penguins in winter. There are also many migratory birds on the surface.
From these meetings and after five years of work Lilian Charistoy has just published Baie de Biscaye – Les Trésors du Gouf de Capbreton, a book of photographs and anecdotes that reveals the wealth of this Gouf de Capbreton.
To make these images, I’m always looking for behavior, special treatment, but without disturbing the animals.
Gouf de Capbreton, in which Lilian observes many species, is a giant underwater canyon. This geological phenomenon of rare biodiversity dives to a depth of 4500 meters with winding slopes, plateaus and abysses.
Its formation took place about 30 million years during the expansion of the Iberian fault. Its proximity to the coast is exceptional: the canyon really starts a few hundred meters from Capbreton (in the Landes) and then continues for about 300 kilometers.
Hot and cold water mix in this canyon, attracting plankton. This is a real pantry for fish and large marine mammals.
Thus, the exceptional biodiversity of Goufs de Capbreton pleases Lilian Charista, as well as professional fishermen who catch a lot of stone or deep-sea fish here.
These beautiful images of bottlenose dolphins should not make us forget that small cetaceans are in danger. Correspondents of the National Strandings Network identified 400 strands. on the Atlantic coast from January to February 2022
The common dolphin makes up nearly 90% of those washed ashore.
Dead animals studied by scientists from the PELAGIS network bear obvious signs of falling into fishing gear.
For Vincent Ridou, professor of biology specializing in marine mammals at the PELAGIS observatory, mortality in fishing gear has been a black point for several decades, especially in our region.

If marine species are in danger, so are vertebrates.
In less than 50 years, 2/3 of wild species have disappeared from the planet, WWF worries.
