“…Its outer lip bears less main teeth (10–12) and the shell is whitish with about 8 brown zigzag zones of flames (not as spots) [ 35 ]. Danilia costellata was referred from the Mediterranean Sea by Palazzi and Villari [ 45 ], Crocetta and Spanu [ 46 ] and Cossignani et al [ 47 ] as certain, by Vilvens and Heros [ 48 ] as doubtful and Herbert [ 49 ] characterized that of Crocetta and Spanu [ 46 ] as tentative. In contrast, D. tinei was referred from the Mediterranean Sea by many more researchers including Gofas et al [ 35 ], Ghisotti and Steinmann [ 50 ], Cachia et al [ 51 ], Navaro and Capdevila [ 52 ], Scaperrotta et al [ 53 ] and Öztürk et al [ 54 ].…”

BackgroundThe Hellenic Seas are influenced by on-going environmental changes and the introduction of alien species, which are expected to have an impact on their biodiversity. This study contributes to the knowledge of the Hellenic marine gastropod biodiversity, expanding data over the entire Greek territory, during the period from October 2008 to March 2017.ResultsThis work presents 45 species of gastropods not previously reported from Greece or reported only once, belonging to 19 families. From those species, one (Horologica sp.) is, most probably, an undescribed species, 17 are new for the Eastern Mediterranean Sea and 40 are new for the Hellenic fauna. Main taxonomic characteristics and ecological information such as habitat, distribution and origin, are given and discussed.ConclusionsBy this report, the Hellenic gastropod biodiversity is enriched by 40 new records, out of which, 17 are new for the Eastern Mediterranean Sea, 4 are Lessepsian migrants previously reported for the Mediterranean Sea and 1 is probably a new species.

“…Denudation can occur through biological (depredation by gastropod molluscs, e.g. Simnia and Coralliophilia species; Crocetta & Spanu 2008) or environmental causes (mortality events and diseases linked to climate warming; see Cerrano et al 2000, Linares et al 2008, Garrabou et al 2009) or due to physical damage (e.g. excessive SCUBA diving activities in particular areas, fishing nets and lines; see Harmelin & Marinopoulos 1994, Tsounis et al 2012, as occurred at our study site.…”

Alcyonium coralloides is an epibiotic soft coral overgrowing living colonies of Mediterranean gorgonians. The main features of the sexual reproductive cycle of this soft coral species are described and quantified for the first time, in a population found at 18 to 22 m depth off the Medes Islands (NW Mediterranean). A. coralloides is a gonochoric internal brooder. The sexual cycle showed a single reproductive event per year. Gametogenesis took 5 to 6 mo, which is the shortest known gametogenesis in littoral octocorals (especially for oogenesis). The maximum mean ± SD diameter was 365 ± 86 µm for spermatic cysts and 632 ± 125 µm for mature oocytes. Sperm was released in spring (late May). Average male and female fecundity in this last phase of the cycle was 15 ± 9 spermatic cysts and 7 ± 4 oocytes per polyp, respectively. Larvae of about 1000 µm in length were observed in the gastrovascular cavities of female colonies in May, before they were released in June. We suggest that the remarkable short gametogenesis and timing shown by A. coralloides is an adaptation to optimize the colonization of its host (in this case the gorgonian octocoral Paramuricea clavata). We conclude that A. coralloides larvae could be ready to settle in early summer when the host P. clavata is probably more vulnerable as a result of its own reproductive cycle coming to an end.

Some of these, despite recognising the priority of Heliciella over Danilia, have continued to use the latter as the valid name.…”

“…Whilst most species seem to be scarce, a Mediterranean species, tentatively identified as Danilia costellata (O.G. Costa, 1861), may be locally abundant in colonies of the gorgonian Corallium rubrum (Linnaeus, 1758) (Crocetta & Spanu 2008). Schepman (1908), Beu & Climo (1974) and De Simone & Kosuge (2010) also reported species living in deep-water coral communities.…”
