In 2020, Deep Blue Exploration's CRUMMA project is selected by the INPN among more than 75 projects. This call for projects aims to improve naturalist knowledge. It is part of the natural heritage inventory mission and the Nature and Landscapes Information System (SINP). It aims to fill gaps in terms of taxa, ecosystems, eras and / or geography, within a framework of knowledge sharing and dissemination.
The CRUMMA program aims to contribute to the inventory of the diversity of CRUstaceans of the Mesophotic reefs of MAyotte CRUMMA. In continuing the DBE strategy, the project focuses on the research, identification and census of free or mutualistic crustaceans (in interaction with a host organism) in different habitats of the mesophotic zone of Mayotte from 30 to 150 m. This project, carried out in the French overseas department of Mayotte, is the first inventory dedicated to the diversity of mesophotic crustaceans using harvesting and observation methods that respect the environment.
