“…Many hydroids are generalists in the use of substrata, with specializations rarely observed in a few taxa (Campos et al 2012;Miglietta and Cunningham 2012). Species of the Family Hydractiniidae usually grow on mollusk shells, especially those inhabiting hermit crabs, but they also occur on other moving and non-moving substrata (Schuchert 2008;Miglietta et al 2009).…”

Two species of Hydractiniidae (Hydrozoa) with metagenetic life cycle have been recorded for the temperate region of the southwestern Atlantic Ocean: the medusa stage of Podocoryna tenuis and the polyp stage of P. humilis. Both the adult medusa of P. humilis and the polyp stage of P. tenuis are unknown, but it is possible that they are different stages of the same species, a hypothesis still to be tested. Colonies of P. humilis growing on the southern king crab Lithodes santolla collected at the Atlantic Patagonian coast, and two small medusae released from these hydroid colonies were analyzed. Medusa of P. humilis were kept alive for 3 days and they were morphologically compared with the medusae of P. tenuis sorted out from ~ 2,500 plankton samples along the Atlantic Patagonian coast. The study of these specimens allowed reassessing the taxonomic status of P. humilis and P. tenuis from the southwestern Atlantic Ocean. Polyp and young medusa stages of P. humilis were described, and additional information was recovered to better describe the medusa stage of P. tenuis. New morphologic and biogeographic evidences in order to propose the synonymy between P. tenuis and P. humilis were discussed.

The objective of this study was to investigate some life history traits of the palaemonid shrimp Typton carneus collected from a reef in northeastern Brazil. Samples of the sponges Amphimedon compressa, A. viridis, Desmapsamma anchorata, Dysidea etheria, Haliclona implexiformis and Tedania ignis were analyzed and shrimps were removed from them. A total of 41 individuals were found in Te. ignis, three in H. implexiformis and one in D. etheria; the latter two sponges are new records of sponge hosts for Ty. carneus. Of the specimens associated with Te. ignis, 24 were males, 10 ovigerous females, six non-ovigerous females and one juvenile male. Fecundity varied between 19 to 56 eggs (37 ± 14) per female, and the mean egg volume was 0.033 ± 0.010 mm³. Eleven heterosexual pairs were obtained. Characteristics of the pairs suggest a monogamous mating system for the studied population, such as: the absence of sexual dimorphism in weaponry and body size and presence of paired non-brooding and brooding females carrying eggs in different development stages; and a sex ratio that does not differ from the expected 1:1. However, the lack of size-assortative pairing as well as the low proportion of pairs, compared to solitary individuals, have been observed in polygamous mating systems.

“…The colonization of the outer surface of S. coralliophaga by a diverse community of sessile suspension feeders in MRC suggests that this sponge acts as a major settlement substrate in that region (see also Klitgaard 1995; Montenegro-Gonzalez and Acosta 2010; De Campos et al 2012;Padua et al 2013). This is further emphasized by the much higher species richness, abundance, and dry biomass in MRC sponges compared to MRC coral rubble.…”

Biodiversity of Spongosorites coralliophaga (Stephens, 1915) on coral rubble at two contrasting cold-water coral reef settings

Cold-water coral reefs (CWRs) in the northeast Atlantic harbor diverse sponge communities. Knowledge of deep-sea sponge ecology is limited and this leaves us with a fragmented understanding of the ecological roles that sponges play in CWR ecosystems. We present the first study of faunal biodiversity associated with the massive demosponge Spongosorites coralliophaga (Stephens, 1915) that typically colonizes coral debris fields of CWRs. Our study focused on the sessile fauna inhabiting sponges mixed with coral rubble at two contrasting settings in the northeast Atlantic: the shallow inshore (120-190 m water depth) Mingulay Reef Complex (MRC) and the deep offshore (500-1200 m) Logachev Mound (LM) coral province. MRC is dominated by the scleractinian Lophelia pertusa, while LM is dominated by L. pertusa and Madrepora oculata. Nine sponge-coral rubble associations were collected from MRC and four from LM. Measurements of abundance, species richness, diversity, evenness, dry biomass, and composition of sessile fauna on sponge and coral rubble microhabitats were undertaken. Differences in community composition between the two regions were mainly a response to changes in fauna with depth. Fauna composition was also different between sponge and coral rubble within each region. Infauna constituted a minor component of the sponge-associated fauna in MRC but had a higher contribution in LM. Sponge and coral rubble sessile fauna in both regions was mainly composed of cnidarians and molluscs, similarly to some previous studies. Sponges' outer surfaces at MRC were colonized by a speciesrich community with high abundance and biomass suggesting that S. coralliophaga at MRC acts as a settlement surface for various organisms but such a role is not the case at LM. This difference in the role of S. coralliophaga as a biological structure is probably related to differences in fauna composition with depth, bottom current speed, and the quantity/ quality of food supplied to the benthos.
