“…during the construction of these tubes, the worm uses complex parapodial and serpentine movements as well as slow peristaltic and antiperistaltic movements of the body (ockelmann & Vahl, 1970). these behaviors seem to be similar to those of the species of Marphysa studied here.…”

“…individuals of the aphroditid species Aphrodita aculeata, when unsheltered show no interest in feeding, whereas when they are buried or inside their tubes, they forage and feed normally (Mettam, 1980). Glycera alba did not feed outside of its tube gallery (ockelmann & Vahl, 1970). in an aquarium, Pholoe minuta, only captured its prey when both the worm and the prey were buried (pleijel, 1983).…”

AbstrActaspects of feeding, such as food capture and ingestion, as well as mobility of the polychaetes Eurythoe complanata, Marphysa formosa and Diopatra aciculata, from São Sebastião channel (São Sebastião, state of São paulo) were observed in laboratory conditions. Eurythoe complanata, a carnivorous species, fed exclusively on pieces of fish with the aid of strong muscular retractable lips, and detected the presence of food by chemical stimuli. Diopatra aciculata, an omnivorous species, captured and ingested different kinds of food with the aid of its jaws, generating a flow of water through its tube by which it detects the presence of food and oxygenates its gills. Marphysa formosa also used its jaws to bite and lacerate food. these species showed greater or lesser degrees of intolerance to light.Keywords: foraging, mobility, aciculata, polychaeta, annelida.resumo Forrageamento e mobilidade em Polychaeta alguns aspectos da atividade alimentar, tais como a captura e ingestão de alimento, bem como a mobilidade dos poliquetas Eurythoe complanata, Marphysa formosa e Diopatra aciculata, procedentes do canal de São Sebastião (São Sebastião, Sp), foram observados em laboratório. Eurythoe complanata, carnívora, alimentou-se apenas de pedaços de peixe, utilizando os lábios retráteis fortemente musculares e detectando a presença do alimento através de estímulos químicos. Diopatra aciculata, onívora, capturou (com o auxílio das maxilas) e ingeriu os diferentes tipos de alimentos oferecidos, promovendo um fluxo de água para dentro do tubo, por meio do qual o animal detecta a presença de alimento e oxigena as brânquias. Marphysa formosa também utilizou as maxilas para morder ou rasgar o alimento. durante as observações, foi constatado que estes poliquetas, em maior ou menor grau, apresentam intolerância à luminosidade.

“…Only the Goniadidae Kinberg, 1865 share some of these characters, but their jaws usually consist of two macrognaths and a variable number of dorsal and ventral micrognaths, and sometimes lateral rows of chevrons are also present (Böggemann 2006a). The glycerids have a worldwide distribution, from intertidal to abyssal depths (Böggemann 2002(Böggemann , 2009, and are generally considered to be carnivorous, capturing prey with their jaws and killing it by the injection of venom (Ockelmann and Vahl 1970;Fauchald and Jumars 1979;Manaranche et al 1980). In most species, the animals form semi-permanent burrow systems in sandy or muddy sediments (Ockelmann and Vahl 1970), whereas a few occur free-living under rocks or crawling on algae (Fauchald and Jumars 1979).…”

A new species of Glyceridae, Glycera noelae sp. nov., was recovered from two distinct colonization experiments based on organic substrates, deployed for 1 year at cold seeps in the eastern Mediterranean Sea (1,694 m depth, Nile Deep-Sea Fan Central Site 2A). The new taxon, which is the first glycerid reported from such an environment, is described by using morphological and molecular methods (18S rDNA, 16S rDNA, COI, ITS1, ITS2).

“…6) indicating of a large proportion of omnivorous species (France et al 1998). δ 15 N values of 14.3, 15.0 and 16.8 ‰ for the carnivorous polychaetes Aphrodita aculeata (Fauchald & Jumars 1979), Glycera alba (Ockelman & Vahl 1970) and Goniada maculata (Mattson 1981) placed these about 2 trophic levels above the bulk sediment. High values, indicative of a predatory feeding mode, were also found for Xenoturbella boecki, whose feeding ecology is virtually unknown, and for Maldane sarsi.…”

Sediment spiked with 14 C-2, 2', 4, 4'-tetrabrominated diphenyl ether (BDE-47) was added as a single pulse, at a low or a high concentration, to intact soft-bottom sediments in a box-cosm system. The vertical distribution of the pollutant and the bioaccumulation in 39 different taxa of macrofauna were analysed after 10, 20 and 29 wk exposure. Throughout the experimental period, 90% of the recovered BDE-47-derived radioactivity in the sediment was found within the upper 5 cm. The BSAF (biota-sediment accumulation factor) in the different taxa after 29 wk exposure varied between 0.4 and 16.3. The correlation between bioaccumulation and lipid content of all individual specimens in each box-cosm was significantly positive and explained between 11 and 64% of the variation. When the fauna was divided into groups with different feeding strategies, it was found that the mean BSAF was significantly higher for the surface deposit-feeders than for the suspension-feeders, subsurface feeders and the predators. The difference increased with time and was larger after 29 wk exposure than after 10 wk. We also tested whether there was a correlation between 15 N enrichment, i.e. trophic position, in the analysed species and bioaccumulation, but no such correlation was found. Water-soluble metabolites of BDE-47 were detected in 15 of the 39 macrofaunal species. There was no observable correlation between the presence of metabolites in the macrofauna and bioaccumulation of the pollutant.
