“…All these analyses were carried out with the PRIMER v.6 (Plymouth Routines In Multivariate Ecological Research) software from Plymouth Marine Laboratory, UK (Clarke and Gorley 2006) and the SPSS software v.16. Some of these multivariate analyses have been used for detecting similarities and differences between groups of benthic samples collected with van Veen dredges (De Leonardis et al 2008, Sciberras et al 2009, Doğan et al 2016.…”

Molluscs of Chella Bank and its surroundings were studied from 21 samples collected with a van Veen grab in the depth range 95-729 m. A total of 299 taxa were identified (77 live-taken), thus increasing by more than 95% the species of molluscs reported in the recently declared site of community importance “Sur de Almería-Seco de los Olivos”. Two of the species are new records to Spanish waters and one to the Alboran Sea. The high species richness observed could be related to the location, the hydrological characteristics and the topographical heterogeneity of the area within the Alboran Sea. Four significant groups of samples were discriminated through multivariate analysis of quantitative data of live-taken molluscs: (I) bathyal muddy bottoms with buried rhodoliths; (II) bathyal muddy bottoms with coral rubble; (III) bathyal hemipelagic muddy bottoms and (IV) bathyal sandy bottoms. Molluscs were more diverse on coral framework bottoms than on sedimentary bottoms around Chella Bank. Most of the live-taken species are widely distributed along the Atlantic and Mediterranean Sea, and a few are strictly Mediterranean. The most striking feature was the occurrence of two species with planktotrophic larval development for which Chella Bank is the sole recorded locality in the Mediterranean (Episcomitra angelesae and Mitrella templadoi) and which elsewhere extremely rare (Mathilda spp.).

“…In the following years, some remarkable studies on the subject have been carried out by Sturany (1895) and Ostroumoff (1896). Afterwards, many studies have been accomplished on the mollusc fauna of the region (Marion, 1898;Kaneva-Abadjieva, 1959;Albayrak and Balkıs, 1996a, b;Türkmen and Demirsoy, 2009;Doğan et al, 2016;Çulha and Şahin, 2018;Bitlis, 2019).…”

In the present study, mollusc species distributed in the Kemer Bay (Sea of Marmara) were determined seasonally (November, February, May, and August) in the years 2010 and 2011. The benthic samples were collected from different biotopes in 16 stations at depth ranging between 0.2 and 5 m by using a quadrate sampling gear. As a result of the evaluation of collected benthic materials, a total of 66 mollusc species belonging to 3 classes (Polyplacophora, Gastropoda, and Bivalvia) were identified. When the number of species and individuals are compared based on the seasons, maximum number of species (46 species) and individuals (168825 ind. m-2) were counted in autumn and spring, respectively. Mytilus galloprovincialis (Lamarck, 1819) and Mytilaster lineatus (Gmelin, 1791) were the most abundant species in all the seasons. Whereas, Bittium reticulatum (da Costa, 1778), Rissoa membranacea (Montagu, 1803), and Tricolia pullus pullus (Linnaeus, 1758) were characterized as species having the highest frequency index values in all seasons.

“…Тем не менее и на остальных станциях было примерно та же картина. Так, Доган с соавторами (Doğan et al 2016) подсчитали, что из 49 видов моллюсков, собранных Остроумовым в батиальной зоне, только 9 видов представлены живыми особями, и из них только 2 вида -брюхоногие моллюски. Такой большой процент мертвых раковин в сборах может быть сезонным явлением, может быть связан с произошедшим 10 июля 1894 г. землетрясением с эпицентром южнее Принцевых островов, охватившим берега Мраморного моря (Шпиндлер [Spindler] 1896), или с особенностями гидрологического режима прибосфорского участка Мраморного моря (Beşiktepe et al 1993)).…”

Heterobranch specimens of the genus Roxania collected during the Russian expedition (1894) aboard the Turkish steamship Selânik to the Sea of Marmara are found in the collection of the Zoological Institute of the Russian Academy of Sciences (Saint Petersburg). One of the aims of the expedition was investigation of the fauna of the Sea of Marmara including its deepest zone to compare with the Black Sea. In 1896 A.A. Ostroumoff published a report on the expedition. Heterobranch mollusks of the genus Roxania are represented in our material by two lots from the first voyage of the expedition to the archipelago of the Prince Islands. The specimens were identified by K.O. Milaschewitsch as Roxania utriculus (Brocchi, 1814) and “Cryptaxis imperforatus n. sp.”, but a description of the last taxon has not been published. In this study, the specimens labeled by Milachewitch as Cryptaxis imperforatus n. sp. were identified as belonging to Roxania monterosatoi Dautzenberg et H. Fischer, 1896. The species is recorded for the Sea of Marmara for the first time; the description and illustrations of the species are presented. Most species of gastropod mollusks collected during the expedition including all samples of Roxania were represented by empty shells. Taxonomical value of the columella morphology in Roxania species is discussed. Based on this character the species of the genus can be divided into two groups: R. utriculus species group (mouth channeled) and R. monterosatoi species group (mouth without a channel). Morphological and molecular phylogenetic investigations are needed to clarify the status of these two groups.
