Les Fruits de Mer is a non-profit French association based in Grand Case, Saint Martin.

Les Fruits de Mer began in 2007 as the world’s first Extreme Shallow Snorkeling team, born from a love of snorkeling and the undersea world. By pioneering the sport, art, and science of E.S.S. (Extreme Shallow Snorkeling) on multinational expeditions, the Les Fruits de Mer team ignited the interest of people around the globe in exploring and celebrating marine wildlife. As more people from more and more countries joined the team, we began to share not only the beauty of the sea but also other natural places, terrestrial wildlife, history, ecology, and cultural heritage, through educational outreach, events, and publications. Our mission organically broadened to include raising awareness of nature, culture, and sport, locally and internationally. To carry it out on a more epic and powerful level, we formed the Les Fruits de Mer Association in 2013.
