Journal de la mission DHEEP aux îles Éparses, du 03 au 30 avril 2019

Abstract : This log illustrates the activities of the DHEEP mission aboard R.V. Marion Dufresne in the Îles Éparses in April 2019. The objective of this mission was to collect the biological material dedicated to a study of the demographic history of the reef fauna of the western Indian Ocean. Collections of fire corals, giant clams, chitons, hermit crabs, brittle stars, sea cucumbers and fishes were made on the reefs of the Europa Islands, Juan de Nova, Glorieuses and Tromelin. Among the highlights of this mission were the collection of specimens of two new species of the fish genus Gymnocranius and the sampling of two rare giant clams currently under taxonomic revision, Tridacna elongatissima and T. rosewateri.
