Dive the coral reefs of the French islands with Alexis Rosenfeld

Coral Reef monitoring mission in the vast lagoon of Mayotte, where a team from the Marine Nature Park is conducting a survey for Reef Check. This scientific programme assesses the state of health of our coral reefs.
This photojournalist has been passionate about the underwater world for as long as he can remember. Through his magnificent images of corals, he is helping to attract attention to these precious ecosystems now under threat. Here, he focuses on the French islands of the tropics with an extract from his exhibition Récifs coralliens, un enjeu pour l'humanité (Coral reefs: a challenge for humanity). From Mayotte to French Polynesia... Dive in!
Incredible biodiversity

Created in 2010, the Mayotte Marine Nature Park was the first to be designated by France in its overseas territories. The waters around the island are home to an incredible level of biodiversity. With most of its coral reefs protected and only marginally affected by pollution and bleaching, underwater life is dense here.

Green sea turtle

It is not unusual to come across beautiful green sea turtles (Chelonia mydas) in the Mayotte lagoon. Essentially herbivorous, these turtles graze the seagrass meadows.

Anemones and clownfish

Corals provide shelter and perfect conditions for a spectacular level of biomass. Here, anemones are home to clownfish among the branches of staghorn coral (Acropora sp.).

Taravai channel

In the Gambier Islands of French Polynesia, snorkelling is the best way to marvel at the beauty of the underwater world in the Taravai channel. In the crystal clear waters of the Pacific Ocean, you can see an enormous number of Acropora corals.

Coral trees

In Moorea lagoon, teams of divers are propagating cuttings of coral on coral trees.

Laboratory of Excellence

French biologist Yann Lacube is researching the effects of ocean acidification on coral. He works on the programme run by Dr. Laetitia Hedouin at CRIOBE, one of the most highly respected French laboratories engaged in coral ecosystem research. Since 2010, CRIOBE has been running the CORAIL Laboratory of Excellence involving 9 overseas institutions and 4 universities.
