“…Even if many sponges avoid predation through the production of secondary metabolites (Clavico et al, 2006), the studied species are strongly exploited by the grazing activity of cidarid echinoids. The presence of sponge spicules in the gut content of these sea urchins was already observed in the Mediterranean Sea by Tortonese (1965) while several observations on the diet of these organisms, based on sponges and corals, were made in cold-water ecosystems (Jacob et al, 2003).…”

The Mediterranean spongofauna is relatively well-known for habitats shallower than 100 m, but, differently from oceanic basins, information upon diversity and functional role of sponge grounds inhabiting deep environments is much more fragmentary. Aims of this article are to characterize through ROV image analysis the population structure of the sponge assemblages found in two deep habitats of the Mediterranean Sea and to test their structuring role, mainly focusing on the demosponges Pachastrella monilifera Schmidt, 1868 and Poecillastra compressa (Bowerbank, 1866). In both study sites, the two target sponge species constitute a mixed assemblage. In the Amendolara Bank (Ionian Sea), where P. compressa is the most abundant species, sponges extend on a peculiar tabular bedrock between 120 and 180 m depth with an average total abundance of 7.3 ± 1.1 specimens m -2 (approximately 230 gWW m -2 of biomass). In contrast, the deeper assemblage of Bari Canyon (average total abundance 10.0 ± 0.7 specimens m -2 , approximately 315 gWW m -2 of biomass), located in the southwestern Adriatic Sea between 380 and 500 m depth, is dominated by P. monilifera mixed with living colonies of the scleractinian Madrepora oculata Linnaeus, 1758, the latter showing a total biomass comparable to that of sponges (386 gWW m -2 ). Due to their erect growth habit, these sponges contribute to create complex three-dimensional habitats in otherwise homogenous environments exposed to high sedimentation rates and attract numerous species of mobile invertebrates (mainly echinoderms) and fish. Sponges themselves may represent a secondary substrate for a specialized associated fauna, such zoanthids. As demonstrated in oceanic environments sponge beds support also in the Mediterranean Sea locally rich biodiversity levels. Sponges emerge also as important elements of benthic-pelagic coupling in these deep habitats. In fact, while exploiting the suspended organic matter, about 20% of the Bari sponge assemblage is also severely affected by cidarid sea urchin grazing, responsible to cause visible damages to the sponge tissues (an average of 12.1 ± 1.8 gWW of individual biomass removed by grazing). Hence, in deep-sea ecosystems, not only the coral habitats, but also the grounds of massive sponges Guest editors: M. Maldonado, X. Turon, M. A. Becerro & M. J.

“…The presence of a speciesspecific chemical cue used in host recognition is evidence of a specialized adaptation that may reflect a fitness advantage. Echinoderms rely on chemical cues to recognize prey items (Sloan & Campbell 1982) as well as associated hosts (Clavico et al 2006, Fourgon et al 2007). In the Florida Keys, Ophiothrix lineata lives primarily in association with Callyspongia vaginalis, and also lives at low frequency (<1%) in the tube sponges Niphates digitalis (Henkel & Pawlik 2005) and Verongula (Aplysina) lacunosa (Kissling & Taylor 1977).…”

On coral reefs off the Florida Keys (USA), the obligate sponge-dwelling brittlestar Ophiothrix lineata lives almost exclusively in the tube sponge Callyspongia vaginalis. We examined chemotactic recognition by O. lineata to assess sponge host preferences using a Y-tube assay chamber. O. lineata preferentially selected seawater conditioned by C. vaginalis relative to seawater controls and showed no preference for seawater conditioned by the infrequent host sponge Niphates digitalis or the non-host sponge Aplysina archeri. When offered seawater conditioned by C. vaginalis and N. digitalis, O. lineata preferentially chose C. vaginalis. Field manipulations examined growth of O. lineata confined to live in all 3 sponge species and the impact of habitat size on growth of O. lineata living in C. vaginalis. Growth of O. lineata was significantly greater in longer (12 cm) tubes of C. vaginalis than in shorter (6 cm) tubes, and while O. lineata was able to survive in A. archeri, growth was greater for brittlestars living in C. vaginalis and N. digitalis. Surveys of O. lineata in C. vaginalis revealed that 74.3% of sponges had at least 1 male and female brittlestar, with 37.1% of sponges having a greater proportion of males, which may increase brittlestar fertilization success. Abundance of O. lineata increased with sponge size and did not differ based on the presence of brooded larvae in sponge tissue. The obligate association of O. lineata with C. vaginalis likely evolved as a consequence of some combination of host abundance, enhanced food availability, and greater probability of mating success in the multi-tubed sponge.

The sponge-dwelling brittlestar Ophiothrix lineata is a species-specific obligate living in association with the tube sponge Callyspongia vaginalis (Henkel & Pawlik 2005). Although O. lineata has been observed living in association with other sponges at low frequency (Kissling & Taylor 1977, Hendler et al. 1995, Henkel & Pawlik 2005, surveys of sponges in the Florida Keys, USA, recorded O. lineata living in C. vaginalis 99% of the time, despite the presence of similarly shaped tube sponges that could provide refuge (Henkel & Pawlik 2005). The association between O. lineata and C. vaginalis has been described as a cleaning mutualism, with O. lineata deposit-feeding on the surface of the sponge (Hendler 1984). Compari...

“…The antifouling property of marine benthic invertebrates from the Brazilian coast are still poorly known; to this date, only a single species of gorgonian, Phyllogorgia dilatata (Esper) and three of sponges were investigated: Geodia corticostylifera Hajdu et al, Mycale microsigmatosa Arndt and Aplysina fulva (Pallas). The extract of G. corticostylifera had strong antifouling activity, preventing the establishment of the bivalve Perna perna in laboratorial tests (Clavico et al, 2006), while extracts of M. microsigmatosa and P. dilatata selectively inhibited the establishment of barnacles and A. fulva did not showed antifouling effects in field experiments (Pereira et al, 2002). As there are more than 300 species of marine sponges in the Brazilian coast, this area of knowledge is clearly little explored in Brazil and there is great potential for the discovery of new antifouling compounds.…”

Benthic marine organisms are constantly exposed to fouling, which is harmful to most host species. Thus, the production of secondary metabolites containing antifouling properties is an important ecological advantage for sessile organisms and may also provide leading compounds for the development of antifouling paints. High antifouling potential of sponges has been demonstrated in the Indian and Pacific oceans and in the Caribbean and Mediterranean seas. Brazilian sponges remain understudied concerning antifouling activities. Only two scientific articles reported this activity in sponges of Brazil. The objective of this study was to test crude extracts of twelve species of sponges from Brazil against the attachment of the mussel Perna perna through laboratorial assays, and highlight promising species for future studies. The species Petromica citrina, Amphimedon viridis, Desmapsamma anchorata, Chondrosia sp., Polymastia janeirensis, Tedania ignis, Aplysina fulva, Mycale angulosa, Hymeniacidon heliophila, Dysidea etheria, Tethya rubra, and Tethya maza were frozen and freeze-dried before extraction with acetone or dichloromethane. The crude extract of four species significantly inhibited the attachment of byssus: Tethya rubra (p = 0.0009), Tethya maza (p = 0.0039), Petromica citrina (p = 0.0277), and Hymeniacidon heliophila (p = 0.00003). These species, specially, should be the target of future studies to detail the substances involved in the ability antifouling well as to define its amplitude of action.Keywords: Porifera, Demospongiae, antifouling, Perna perna, Brazil. Atividade anti-incrustante de doze demosponjas do Brasil ResumoOrganismos bentônicos marinhos estão expostos constantemente à incrustação, que pode ser danosa para a maioria das espécies. Assim, a produção de metabólitos secundários com propriedades anti-incrustantes é uma vantagem ecológica importante para organismos sésseis e pode também orientar o estudo de substâncias para o desenvolvimento de tintas anti-incrustantes. O alto potencial anti-incrustante de esponjas tem sido demonstrado nos oceanos Índico e Pacífico, nos mares Mediterrâneo e Caribenho. Esponjas brasileiras permanecem pouco estudadas em relação à atividade anti-incrustante. Apenas dois artigos científicos registraram essa atividade em esponjas do Brasil. O objetivo desse estudo foi testar os extratos brutos de doze espécies de esponjas do Brasil contra a fixação do molusco Perna perna através de ensaios laboratoriais e também destacar espécies promissoras para estudos futuros. As espécies Petromica citrina, Amphimedon viridis, Desmapsamma anchorata, Chondrosia sp., Polymastia janeirensis, Tedania ignis, Aplysina fulva, Mycale angulosa, Hymeniacidon heliophila, Dysidea etheria, Tethya rubra e Tethya maza foram congeladas e liofilizadas logo após a coleta e posteriormente procedeu-se a extração com acetona ou diclorometano. O extrato bruto de quatro espécies inibiu significativamente a fixação de bissos: Tethya rubra (p = 0.0009), Tethya maza (p = 0.0039), Petromica citrina (p...
