In the Mediterranean deep-sea two scleractinian species, Lophelia pertusa (= Desmophyllum pertusum) and Madrepora oculata, make up the dominant structure-forming corals. The Lacaze-Duthiers canyon is the only French Mediterranean canyon where the two species L. pertusa and M. oculata have been observed living together in large quantities, the situation generally described for the biocoenosis of cold-water corals (CWC). In this canyon large colonies (more than 40 cm) of both species of scleractinians were observed at depths ranging from 246 m to 541 m at the head of the canyon and its western flank. The second canyon is the Cassidaigne canyon, where M. oculata seems to be the only structure-forming scleractinian there. The largest concentration of M. oculata colonies was observed on the west flank of the canyon along a crest at depths ranging from 200 to 210 m. Mature M. oculata colonies attained heights up to 40 cm. M. oculata were observed in three other canyons: Bourcart, Sicié and Var. In the Bourcart canyon, M. oculata was observed on a shelf of hard substratum at 331 m depth. Several single branches protruded from a slab. In the Sicié canyon a 15-cm colony of M. oculata was observed at 255 m depth, while in the Var canyon, three young branches 2 cm long were seen growing at 350 m depth on a wall of hard rock.

Spatial distribution of quarterly harbor seals (Phoca vitulina) identified by Aérobaie and the Réserve Naturelle du Domaine de Beauguillot (Nature Reserve of Beauguillot) on their haul out sites in the Bay of Somme from 2007 to 2009 inclusive.

Compact mud facies with Isidella elongata is a relevant habitat for red shrimps (Aristeus antennatus and Aristaeomorpha foliacea). These habitats are potentially vulnerable as they are targeted by fisheries.These VME fauna seem to have been swept away by repeated trawling. Vulnerable Marine Ecosystems (VME) in the deep Mediterranean Sea have been identified by the General Fisheries Commission for the Mediterranean as consisting of communities of Scleractinia (Lophelia pertusa and Madrepora oculata), Pennatulacea (Funiculina quadrangularis) and Alcyonacea (Isidella elongata). This dataset concerns video data recorded in the heads of French Mediterranean canyons. Quantitative observations were extracted from 101 video films recorded during the MEDSEACAN cruise in 2009 (Aamp/Comex), in addition to 12 Ifremer dives. Species recognized in the video films were recorded from 180 to 700 m depth, and were mapped using GIS. Isidella elongata was abundant in three canyons of the Gulf of Lion (Bourcart, Marti, Petit-Rhône).

Ces données sont une estimation du nombre annuel de femelles présentes sur les principaux sites de reproduction : Europa, Glorieuses, Juan de Nova, Mayotte, Mohéli, Mozambique, Tromelin, Iranja, Farquhar, Aldabra, Cosmoledo, Amirantes et Granitics. Ces données sont issues du projet "génétique tortue" porté par Kélonia/Ifremer.

Seconde partie (sous-forme de ponctuels) de la carte représentant les zones de de la baie du Mont Saint-Michel fréquentées comme nurserie par le tadorne de Belon (Tadorna tadorna) en période de reproduction. Cette espèce atteint occasionnellement le niveau d'importance internationale en baie du Mont Saint-Michel.

Les données acquises entre 2001 et 2015 par balise Argos, ont été analysées pour sortir 2 localisations par jour. Le nombre de localisations de Tortues vertes balisées à Mohéli est agrégé par carré de 1° de côté. Ce mode de calcul est celui choisi dans le cadre du projet Mégafaune pour toutes les populations (une espèce, un lieu) étudiées afin de permettre l'inter-comparaison. Ces suivis post-reproduction ont eu lieu dans le cadre des projets "DYMITILE" Kelonia / Ifremer.
