Our association was born of a sincere desire to contribute to the protection of chameleons and their ecosystem. The president and founder, Sébastien METRAILLER, is a man with a lifelong passion for herpetological fauna and aquatic ecosystems. Author, trainer, lecturer, breeder and project management expert, he is a member of the IUCN Tortoise and Freshwater Turtle Specialist Group, vice-president of the PRT association (Protection et récupération des Tortues, Centre Emys) and founder of the ZooConseil consultancy.​

Véronique PIOUCEAU is committed to this project, which was born out of a deep conviction that everyone can contribute to a better world by raising their awareness and reconnecting with what makes them tick. A therapist, coach, photographer and multi-talented individual, she supports people who are on a quest for meaning and harmony.

Thanks to her interpersonal, communication and artistic skills, she actively supports the association's efforts, particularly through communication and the creation of visual content (photography, video editing).

With a doctorate in biology, Olivier MARQUIS is curator of reptiles and amphibians at the Parc zoologique de Paris, part of the Muséum national d'Histoire naturelle. He is also a lecturer, field biologist, lecturer in various animal keeper training courses, expert on numerous commissions, member of the IUCN Crocodile Specialist Group and Chameleon Specialist Group, and co-leader of the amphibian specialist group of the European Association of Zoos and Aquariums (EAZA).

Capacitarian and consultant in herpetoculture, Benoît de VILLELONGUE is the founder of Herpéto-technique, which specialises in assisting zoological structures in the zootechnical approach and the design of infrastructures for captive reptiles and amphibians. Passionate about the animal world and a reptile breeder, he trained as an animal keeper and has worked in various zoos, including the ZooParc de Beauval, as well as in a number of private and public facilities.

As a student and amateur photographer, Rayane VUILLEMIN has always been fascinated by the diversity of the animal kingdom. Photography has been his way of getting close to animals.  Long interested in birds and mammals, his photographic approach centered on the notion of species led him to visit over 100 zoos and discover herpetology. He publishes images of his work on his website

A naturalist and terrarium enthusiast, Martin ETAVE has always had a passion for the richness of living things. He is particularly interested in the study and conservation of chameleons.

Anderson (IUCN - SSC Chameleon Specialist Group), taking part in research into the evolution, ecology and physiology of these animals.​

Benjamin DROUET, veterinary doctor at the Besançon Museum, is passionate about medicine and the conservation of endangered species, particularly Madagascan wildlife. He trained at institutions involved in the conservation of this endemic fauna, at the Parc zoologique de Paris and the Parc Zoologique et Botanique de Mulhouse. His experience as a wildlife veterinarian has enabled him to develop skills in projects that link zoos and in situ conservation stakeholders.
