| The structure of the cumacean assemblages from the southern margin of the Cap Ferret Canyon was studied at 13 stations ranging from 346 to 1099 m depth with a modified Macer-GIROQ suprabenthic sledge (four superimposed nets; 0.5 mm mesh size). A total of 1885 specimens were collected and classified into 5 families and 42 species. The total abundances fluctuated between 2.8 ind./100 m2 (station TS04; 484-485 m) and 55.8 ind./100 m2 (station TS08; 714-708 m). The highest values of species richness and diversity were recorded at station TS13 (1097-1099 m): S=25 species; H’(log2)=4.05. The near-bottom vertical distribution of the cumacean fauna showed the same pattern at all stations: at least 60% of the individuals were sampled by the lower net of the sledge... |

| Cette réflexion a été réalisée dans le cadre du Bon Etat Ecologique pour la DCSMM (Directive Cadre pour la Stratégie sur le Milieu Marin). Elle est préalable à la construction d'un indicateur de l'Etat Ecologique des communautés benthiques du domaine profond, pour lesquelles il n'existe rien actuellement. Cette réflexion fait suite à une étude bibliographique des indices existants. Voir rapport ci-après: Pedel, L., Fabri, M.C., 2012. Etat de l'art sur les indices existant concernant l'Etat Ecologique des habitats benthiques du domaine profond. DCSMM Bon Etat Ecologique (Ministère de l'Écologie, du Développement Durable, des Transports et du Logement), Ifremer, 1-71. |

| Discorhabdella pseudaster n. sp. is an incrusting sponge from the upper bathyal zone of the 'Banc du Geyser', north of Madagascar, Mozambique Channel This new species is described only from a single specimen but it is remarkable by the presence of spicules similar to euasters, a type of microsclere unknown in Poecilosclerida. These spicules are in fact a new example of homoplasy, being derivatives of the typical Discorhabdella pseudoastrose acanthostyles, which are here reduced to the aster-like tyles. The isochelae with a large lamella on the shaft are also quite unique in Poeciloclerida. |

| Ce guide reprend l'ensemble des métriques proposées dans le cadre de la stratégie de surveillance nationale des écosystèmes benthiques profonds évoquées dans le rapport "mesure de l'état écologique des habitats benthiques du domaine bathyal à partir de l'imagerie optique (Sélection de métrique et proposition d'une stratégie de surveillance = stratégie d'échantillonnage)" (Pedel et al. 2013). Il décrit les différentes méthodes d'acquisition vidéo selon les métriques à mesurer: 1.4 Répartition des écosystèmes 1.5 Etendue d'un habitat 1.6 Etat des communautés benthiques (Densité, Taux de couverture, Richesse et composition spécifique, Etat des colonies) 1.3 Structure de taille d'une population Une validation des standards reste à faire avec les pays européens... |

| This paper documents the species of Pectinoidea Rafinesque, 1815 collected in Vanuatu during the SANTO 2006 expedition. A total of 49 species (13 Propeamussiidae Abbott, 1954, 4 Cyclochlamydidae n. fam., 1 Entoliidae Teppner, 1922, and 31 Pectinidae Rafinesque, 1815) are represented, of which 70% are new records for Vanuatu. A new family, Cyclochlamydidae n. fam., is established for the genera Cyclochlamys Finlay, 1926, Chlamydella Iredale, 1929 and Micropecten n. gen., formerly placed in Propeamussiidae, but differing by their sculptured prodissoconch (smooth in Propeamussiidae), an occasionally antimarginally sculptured right valve (smooth or weak commarginally sculptured in Propeamussiidae), a (common) simple outer prismatic layer of longitudinally... |

| Eighteen species of Pectinoidea (six Propeamussiidae Abbott, 1954, one Entoliidae Teppner, 1922, eleven Pectinidae Rafinesque, 1815) are listed from the Tarava Seamounts, Society Islands and Tuamotu Archipelago, French Polynesia. Four Propeamussiidae species (Parvamussium lamellatum n. sp., Parvamussium scutulatum n. sp., Parvamussium vesiculosum n. sp., Cyclopecten comptulus n. sp.) are new to science. |

| Twenty-nine species of Pectinoidea (12 Propeamussiidae, 1 Entoliidae, 16 Pectinidae) are recorded from the Austral Islands, the southernmost archipelago of French Polynesia. One genus (Pectinidae: Lamellipecten n. gen.) and five species (Propeamussiidae: Parvamussium australanum n. sp., Cyclochlamys australensis n. sp., Cyclopecten ambiguus n. sp.; Pectinidae: Lamellipecten aduncus n. gen., n. sp., Mimachlamys erycina n. sp.) are new to science, and most others are new records for the archipelago. The near-shore fauna of Rapa has 12 species of Pectinidae, and half of these have narrow-range distributions. Such a remarkably high level of marine endemism is shared by other mollusc taxa on Rapa. |
