A new dorvilleid species belonging to the genus Ophryotrocha is described from circalittoral seabeds (70-100 m) in the Cantabrian Sea (NE Atlantic Ocean). Ophryotrocha cantabrica is characterized by having well developed antennae and palps, parapodia with long dorsal cirrus, as well as, P-type maxillae and bifid mandibles slightly tagged. The most closely related species are O. longidentata and O. lobifera. http://journals.cambridge.org/action/displayAbstract?fromPage=online&aid=8966156

Prestige oil-spill scarcely scarcely affected the macroinfaunal community structure during the study period (2003–2009) and its effect was limited just to the first campaign (2003), six months after the Prestige accident. Two different communitites were found depending on the intertidal level, supralittoral and intertidal. The former one was dominated by talitrids amphipods, isopods and terrestrial insects. Polychaetes, isopods (Eurydice spp) and the amphipod Pontocrates arenarius prevailed in the intertidal. Check it out here!!. Junoy, J., C. Castellanos, J.M Viéitez, R. Riera. 2013.

Confluence of pollutants or perturbations is common at coastal areas. The combined disposal of sewage and brine affected meiofauna assemblage structure on the surrrounded sandy bare seabeds, with an increase of nematodes due to the organic enrichment from sewage disposal. Differences of grain size composition in the affected sediments explained part of the observed meiofauna variability throughout the study period. As a result, meiofauna could be considered a reliable monitoring tool for studying the environmental effects of combined disposals on coastal assemblages. Riera, R., F. Tuya, A. Sacramento, E.
