“…Currently there are 77 accepted species in the genus Cliona (Van Soest et al , 2015). Cliona species are fairly well known from the Mediterranean Sea and neighbouring areas of the Eastern Atlantic (14 species: Von Lendenfeld, 1897; Rützler & Bromley, 1981; Topsent, 1932; Van Soest, 1993; Carballo et al ., 1994, 1997; Corriero & Scalera-Liaci, 1997; Rosell & Uriz, 2002; Corriero & Nonnis Marzano, 2006; Calcinai et al , 2011), Australia (15 species: Carter, 1886; Topsent, 1888, 1932; Hooper & Wiedenmayer, 1994; Schönberg, 2000a; Fromont et al , 2005; Schönberg et al ., 2006; Van Soest et al , 2015), and best-studied in the Tropical Western Atlantic, especially in the Caribbean region (24 accepted species: De Laubenfels, 1950; Pang, 1973; Rützler, 1974; Duchassaing & Michelotti, 1864; Sollas, 1878; Carter, 1882; Topsent, 1888; Leidy, 1889; Van Soest, 1993; Holmes, 2000; Zea & Weil, 2003; Miloslavich et al ., 2010; Friday et al ., 2013; Van Soest et al , 2015), while subareas of the above and other regions are under-represented.

Bioeroding sponges of theCliona viridisspecies complex play a large role in carbonate cycling and reef health. In the present study we provide the first record and a description of a Mediterranean lineage ofC. viridis(Schmidt, 1862) in the south-western Atlantic. Specimens were collected in Maricás Archipelago, Rio de Janeiro State in September 2010 by scuba diving at 10–12 m depth and deposited in the Porifera collection of Museu Nacional, Universidade Federal do Rio de Janeiro. Morphologically, the specimens presently examined are very similar to those described in the beta and gamma growth form from the Mediterranean. The Brazilian and Mediterranean specimens share large and irregular papillae over 2 cm in diameter, megasclere tylostyles up to 500 µm long and microsclere spirasters with up to five twists and 34 µm long. A Maximum Likelihood analysis of 28S rDNA ofC. viridis, C. aprica, C. jullieni, C. schmidtiandC. varianswas performed for a genetic identification of the Brazilian specimens. The Brazilian material is phylogenetically closer to the MediterraneanC. viridisthan to the Caribbean and Indian Ocean members of this species complex included in the present analysis. Our results suggest thatC. viridisis a cryptogenic species with a distribution extending from the Mediterranean to the eastern Atlantic and in the SE Brazilian coast or further.

“…Several studies have been dedicated to explore the diversity and the role of the Mediterranean excavating sponges (e.g. Futterer, 1974; Rützler, 1974; Rützler & Bromley, 1981; Corriero et al , 1988; Rosell & Uriz, 1991; Barbieri et al , 1995; Bavestrello et al , 1996, 1997; Corriero & Scalera-Liaci, 1997; Calcinai et al , 2000; Corriero & Nonnis Marzano, 2006). Regarding the Adriatic Sea this group has mainly been studied in the Rovinj region, in the north-eastern portion of the basin (Schmidt, 1862; Lendenfeld, 1897; Volz, 1939; Rützler, 1965, 1967) and in its southern part (Tremiti Islands and Apulian coast) (Sarà, 1961; Corriero et al , 2000).…”

Excavating sponges from the Adriatic Sea: description ofCliona adriaticasp. nov. (Demospongiae: Clionaidae) and estimation of its boring activity

et al. 2010

Boring sponge diversity in the area of the Conero Promontory, the most important rocky emergence on the west coast of the Adriatic Sea (Italy), was assessed. Four species were recorded; one of them,Cliona adriatica, is new and is described here. The new species differs from all the other excavating sponge species, characterized by yellow papillae and lacking or scarcity of microscleres, in the large size of the boring chambers and the presence of numerous styles.Cliona adriaticais present on about 12% of the surface of rocky bottoms in the Conero Promontory area. The impact of this highly destructive species on the carbonatic micritic rock of the promontory was evaluated calculating a relationship between the volume of the boring chambers and the surface of the epilithic portions. Consequently, it was estimated that 1 cm2of epilithic tissue corresponds to 8.5 g of excavated rock. The recorded correlation between the excavated volume and the area of the papillar zone (roughly the area of the substratum affected by the erosion) allows an estimation of the substratum removed by a boring sponge, using only visually oriented, non-destructive, sampling methods.

The aim of this paper was (1) to update sponge diversity and distribution in the Mediterranean and (2) to re-examine faunal relationships among the Mediterranean areas on the basis of their sponge fauna. The Mediterranean demosponge faunal list was updated to 629 species by taking into consideration recent data from previously poorly studied areas. The species lists of 14 Mediterranean areas were compared on the basis of their sponge species richness, species composition, and taxonomic relatedness of species using multivariate analyses and diversity measures, such as PD, Delta?, and Lambda?. The 14 Mediterranean areas examined for their diversity and affinities were assembled into four major zoogeographic groups: the northwestern, northeastern, the central zone, and southeastern areas. Richest in species numbers were the areas belonging to the two northern groups. The species richness comparisons and similarity analyses performed at the generic level showed that it can be safely used as a surrogate for sponge species diversity in the Mediterranean. The results of this study showed that the simple traditional division of the Mediterranean Sea into a western, central, and eastern basin cannot reliably describe the distribution of sponges in the area. Thus, the W to E faunal decline previously presented for several faunal groups shifts to a general NNW-SSE pattern when one examines separately the northern and the southern parts of the traditional basins. This gradient seems to be in agreement with differences in key environmental variables, such as latitude, salinity, temperature, and water circulation, besides the typically examined distance from Gibraltar.
