Two new species of isopod crustaceans belonging to the genus Stenosoma Leach, 1814 (Valvifera, Idoteidae) are described, illustrated, and compared with the other known species of the genus. The new species can be distinguished both from each other and from all their congeners by having a maxilliped with two coupling hooks; length of the appendix masculina on pleopod II; and an antennal flagellum with 12 articles in Stenosoma aaseni sp. nov.; and by having a pair of distinctive lateral spinous tubercles on pereonites I-II; and a pereon with a part of a mid-dorsal carina on the posterior half of each of the pereonites in Stenosoma inonuei sp. nov.; the two new species also differ in the morphology of mouthparts, pleotelson, and pereopods. Both new species were collected from seagrass meadows, colonized predominantly by Zostera (Zostera) marina Linnaeus, 1753 and Posidonia oceanica (Linnaeus) Delile, 1813, in the Sea of Marmara, Turkey. An up-to-date morphological identification key to species level for to genus Stenosoma is also provided. © Koninklijke Brill NV, Leiden, 2015.

Cytherella maremensis sp. n., belonging to the family Cytherellidae, is described as new from a hydrothermal vent, located in the west of Marmara Island on the North Anatolian Fault crossing the Sea of Marmara. It was collected from a sediment core 55 m below sea level. Cytherella maremensis sp. n. is clearly separated from closely related species by its shape, length-height ratio and ornamentation. © 2013 Taylor & Francis.

Aggregates of the Polychaeta Phyllochaetopterus socialis were recorded for the first time off Gemlik Bay in the Sea of Marmara, in August 2008. These were found at about 53 m depth, on the soft sediments around the sub-sea part of the North Anatoly Earthquake Fault. Samples were landed by beam trawl. Total wet weight of the mats was 58 kg. Forty-three species belonging to 10 phyla associated with P. socialis were recorded from the whole landing materials. Echinodermata and Gastropoda were the most abundant (12 and 8 species, respectively). Shannon-Wiener diversity and Margalef species richness indices were applied to analyse the structure of benthic communities. Presence and abundance lognormal distribution of the species and communities in mat habitat are shown. The hydrographic environment of the water mass is also discussed. © Marine Biological Association of the United Kingdom, 2014.

In August 2008 eight specimens of the hollowsnout grenadier, Coelorhynchus coelorhyncus, were caught by beam trawl off Barbaros in the Sea of Marmara, Turkey. The study represents the first record of this species in the Sea of Marmara. © 2009 Blackwell Verlag, Berlin.
