Macro- and megafauna were recorded in the submarine Bari Canyon (southern Adriatic Sea, Mediterranean Sea) during an oceanographic cruise carried out in May-June 2012 and an experimental fishing survey conducted in November 2013. During the former, a total of 20 benthic samples were taken using a Van Veen grab at depths between 268 and 770 m and 4 deployments of a baited lander, for about 43 hours of video records, were carried out at depths between 443 and 788 m. During the latter, 8 longline fishing operations were conducted from 338 down to 612 m. Eighty-five living benthic and benthopelagic species were recorded: 29 Porifera, 1 Cnidaria, 2 Mollusca, 11 Annelida, 1 Arthropoda, 19 Bryozoa, 3 Echinodermata and 19 Chordata. A total of 51 species are new records for the Bari Canyon, 29 new records for the Adriatic Sea. Among the Porifera Cerbaris curvispiculifer is a new addition for the Italian Sponge Fauna. The first certain record of living specimens for the bryozoan Crisia tenella longinodata is reported. A total of 6 Mediterranean endemic species have been identified: 4 Porifera and 2 Annelida. The bathymetric range of some species has been extended. New information acquired for deep sea species confirms their importance in the structure of cold-water coral communities. This study has updated the knowledge on the biodiversity of the Adriatic Sea, as well as of the Bari Canyon in particular, one of the sites designated as “jewels of the Mediterranean” for which urgent conservation measures are needed.

“…Pansini & Longo (2003), followed by Voultsiadou (2009), were the first to provide a comprehensive account of the diversity and biogeography of the Mediterranean sponges. Both studies recognized the contribution of the Atlantic Ocean to the diversity patterns seen in the Mediterranean, but the lack of an analysis combining data from both areas has obscured our understanding of the relationship between them.…”

Recognizing and understanding presentday biodiversity and biogeographical patterns and how these relate to contemporary and past climate is pivotal to predict the effect of future climate on marine biodiversity and promote adequate conservation policies. Sponges constitute an important and dominant component of the marine benthos and are therefore an excellent model group for such investigations. In this study, we assessed the diversity patterns and the zoogeographical affinities of the Northeast Atlantic and Mediterranean shallow-water demosponge assemblages. Data on the distribution of 745 species throughout 28 areas was compiled from the literature and used to build a presence/absence matrix. Diversity patterns were assessed from estimates of species richness (S) and taxonomic distinctness (AvTD). The Mediterranean Sea proved to be more diverse both in terms of species richness and taxonomic distinctness (S = 539, AvTD = 94.74) than the Northeast Atlantic (S = 480, AvTD = 92.42) and the two regions together were found to constitute a diversity hotspot harbouring approximately 11% of the global demosponge diversity. We found an Atlantic N-S and a Mediterranean NW-SE gradient of increasing taxonomic distinctness that is strongly correlated to both contemporary (R 2 = 0.5667; P \ 0.01) and historical values (R 2 = 0.7287; P \ 0.01) of sea surface temperature (SST) at the Last Glacial Maximum (LGM). The zoogeographical affinities examined through classification (cluster analysis) and ordination (nonmetric multidimensional scaling, nMDS) based on the Bray-Curtis similarity index, revealed the presence of three groups approximately corresponding to the Northern European Seas, Lusitanian and Mediterranean provinces outlined in the 'Marine Ecoregions of the World' (MEOW) classification system. Geographical distance and oceanographic circulation were shown to constitute important factors in shaping the zoogeographical affinities among areas. The vast majority of the species occurring in the Northeast Atlantic and the Mediterranean (67 and 57%, respectively) was shown to have extremely restricted geographical ranges, as single-area or narrow-range (2-3 areas) endemics, which raises some concerns regarding their conservation.

“…The Ionian sponge fauna remains poorly known in spite of a large number of studies on the taxonomy and distribution of Mediterranean sponges which, however, mainly refer to the western coasts (see Pansini & Longo 2003).…”

“…Pansini & Longo (2003) report 12 species belonging to this genus for the Mediterranean. They agree with Rosell & Uriz (1991, 2002) who consider C. copiosa Sarà, 1959, C. nigricans (Schmidt, 1862) and C. tremitensis Sarà, 1961 as different growth stages of C. viridis (Schmidt, 1862) (the so called ''Cliona viridis complex'').…”

“…Nine species of Cliona (namely C. topsenti (Lendenfeld, 1896), C. vermifera, C. celata, C. copiosa, C. nigricans, C. rhodensis Rü tzler & Bromley, 1981, C. parenzani Corriero & Scalera Liaci, 1997, C. schmidti (Ridley, 1881 and C. viridis) have been reported for the Ionian Sea (Pulitzer-Finali 1983;Corriero et al 1984;Corriero 1990;Corriero & Scalera Liaci 1997;Pansini & Longo 2003). The present work describes a new species of Cliona, C. spissaspira, collected along the Ionian coast of Italy (Porto Cesareo, Apulia).…”

A new species of the genus Cliona is described: Cliona spissaspira sp. n., collected at 1 m depth in a shallow bay of the Ionian coast of Apulia (Southern Italy). The species, erected on the basis of the finding of two small specimens, shows a boring habitus, with an irregular pattern of galleries and spaciously distributed perforating chambers. Its colour varies from orange to light brown. The spiculation consists of short robust tylostyles, together with smooth thick spirasters. The latter vary in length and shape, and constitute the main diagnostic character of the species. The affinity of these species with other Mediterranean Clionaidae is discussed.
