“…Polychaetes are usually one of the dominant groups in sponges (see Supplementary material Appendix 1). A clear relationship between faunal densities and sponge morphology was established by comparing many studies and, for example, in the case of a syllid species, it was reported that lobate sponge species are able to grow faster than massive ones, supporting higher densities of worms (Neves and Omena 2003). Considering the endofauna hosted by other Mycale species Nalesso 1996, Ribeiro et al 2003 , Table 1), in which polychaetes were the dominant group in one of the species but crustaceans were dominant in the other one, it remains unclear whether the morphology or internal architecture of M.…”

SUMMARY: The composition of endobionts in the sponge Mycale (Aegogropila) magellanica at the shelf-break, near 100 m depth, in the Argentine Sea was studied. We also provide new information on the distribution of M. (A.) magellanica, extending its northern limit to 38º36.02'S and 55º44.68'W, 91 m in the SW Atlantic Ocean. The main Patagonian scallop fishing grounds are located in the shelf-break frontal area of the Argentine Sea. In this area, M. (A.) magellanica plays an important role in providing habitat for at least 23 taxa of small invertebrates, mostly crustaceans (66% to 96% of the total number of individuals). On average, this sponge hosted 348 individuals per litre; Aristias cf. antarcticus (Amphipoda) was the most frequent and abundant species. Other organisms commonly found were the isopod Caecognathia sp., the amphipod Leucothoe cf. spinicarpa, the bivalve Hiatella meridionalis and the ophiuroid Ophiactis asperula. As previously demonstrated for other sponges, our study suggests that M. (A.) magellanica enhances benthic biodiversity, as it shelters a variety of invertebrate species. In areas of soft and flat substrate, erect and sessile epifauna usually acts as an ecosystem engineer, structuring the architecture of the habitat by increasing the sea-bottom complexity. Mass removal of this fauna due to intense trawling activities on Patagonian scallop beds could have devastating effects on local biodiversity.Keywords: Mycale (Aegogropila) magellanica, sponge-invertebrate associations, benthic richness, Argentine Sea. RESUMEN: Mycale (aegogropila) Magellanica (Porifera: Demospongiae) en el Atlántico suroeste: fauna endobiótica y nuevos datos de su distribución. -Se estudió la composición de endobiontes de la esponja Mycale (Aegogropila) magellanica, recolectada en el área del talud del Mar Argentino, a una profundidad promedio de 100 m. Se presenta también nueva información sobre la distribución de M. (A.) magellanica, extendiendo su límite norte hasta los 38º36.02'S y 55º44.68'W, 91 m en el Atlántico Sudoccidental. En el Mar Argentino, los principales bancos de vieira patagónica están situados en el borde externo de la plataforma, en el área frontal del talud. En esta región, M. (A.) magellanica juega un papel importante al proveer hábitat para al menos 23 taxones de invertebrados pequeños, en su mayoría crustáceos (66 al 96% del total de individuos). En promedio, esta esponja alberga 348 individuos por litro de esponja, siendo Aristias cf. antarcticus (Amphipoda) la especie más frecuente y abundante. Otros organismos hallados con frecuencia fueron el isópodo Caecognathia sp., el anfípodo Leucothoe cf. spinicarpa, el bivalvo Hiatella meridionalis y la ofiura Ophiactis asperula. Tal como se ha encontrado en otras esponjas, nuestros resultados sugieren que M. (A.) magellanica enriquece la biodiversidad local al proveer refugio a una gran variedad de invertebrados bentónicos. En áreas de sustrato blando, la epifauna eréctil y sésil estructura la arquitectura del hábitat, aumentando la complejidad del fond...

“…Furthermore, in Brazil, little information is available about the ecology and biology of coral-associated fauna (Young, 1986;Nogueira, 2003). Our knowledge is restricted to taxonomic aspects of barnacles (Young & Christoffersen, 1984;Young, 1986Young, , 1988Young, , 1989, polychaetes (Nogueira & Rizzo, 2001;Nogueira & Amaral, 2000;Neves & Omena, 2003;Nogueira, 2003) hydroids (da Silveira & Migotto, 1984) and bioeroding sponges (Reis & Lea˜o, 2000).…”

This study describes the distribution and abundance patterns of the associate fauna on the living surface of the corals Siderastrea stellata Verril, 1868 and Mussismilia hispida (Verril 1902) using a non-destructive method, on the northern coast of Rio de Janeiro State. For each coral species, infestation density and proportions of infested colonies, colonies attached and unattached to the substrate were estimated. A total of 474 colonies of S. stellata and 452 colonies of M. hispida were examined. The barnacle Ceratoconcha floridana (Pilsbry, 1931) was the dominant coral associate found, followed by gall-crabs of the family Cryptochiridae Paulson, 1875 and the bivalve Lithophaga bisulcata (d'Orbigny, 1842). Both coral species presented similar patterns of infestation dominance. S. stellata colonies were more commonly infested and showed a greater mean infestation density of 0.62 ind/cm 2 at Armac¸a˜o dos Bu´zios, whereas M. hispida colonies had infestation densities of only 0.20 ind/cm 2 . Infestation density does not appear to impact negatively on corals of Armac¸a˜o dos Bu´zios. A clear negative relationship between the number of associates in the coral colony and coral size was found. Evidently abundance and frequency of occurrence of associated fauna is highly related to coral community structure and composition and the results highlight the importance of local scale studies.

“…The most common hosts for species of Haplosyllis are sponges (Duarte & Nalesso 1996;Martin & Britayev 1998;López et al 2001;Çinar 2003;Martin et al 2003;Neves & Omena 2003), gorgonians (López et al 1996;Martin et al 2003), bryozoans (Morgado & Tanaka 2001), intertidal and sublittoral algae (Çinar 2003;Giangrande et al 2003;Antoniadou et al 2004), and seagrasses (Bone & San Martín 2003;Çinar 2003;Lattig et al 2007). …”

Two new species of Haplosyllis collected along the coast off northeastern Brazil are described. Haplosyllis amphimedonicola sp. nov. lives in close association with the sponge Amphimedon viridis and is characterized by having midbody dorsal cirri alternating long (with 3-7 articles) and short (with 1-3 articles), with long cirri not reaching half the body width. Ciliated anus dorsally and pair of smooth to irregularly articulated anal cirri; chaetae bidentate, often with eroded tips, main fang about same length or shorter than shaft width, mid-joining point straight and long, upper side of main fang with few, short denticles. Haplosyllis rosenalessoae sp. nov. is characterized by having body wall of midbody to posterior chaetigers with internal iridescent and granulose inclusions, arranged in continuous transverse rows across chaetigers, broader laterally, at base of parapodia, progressively narrower towards dorsal mid-line. Bidentate chaetae, with long and pointed main fang, about same width as shaft, slightly stouter posteriorly. Chaetae on posterior parapodia with apical teeth very close to each other, nearly unidentate at first glance, upper side of main fang smooth; 2-3 aciculae in each midbody parapodium. A table comparing all valid species of Haplosyllis is provided.
