Nuchal Organs of the Polychaete Parapionosyllis manca (Syllidae)
Invertebrate Biology, 1996Nuchal organs are known to be important sensory organs of many polychaete annelid species. This study describes the fine structure of the nuchal organs and associated glands of Parapionosyllis manca. In each nuchal organ, the ciliated epithelium of the nuchal cleft encloses an olfactory chamber through which sensory cilia and microvillus-like processes

The diversity of diets in Syllidae (Annelida: Polychaeta)
2000Results from examination of fecal pellets and gut content of some syllid species (Polychaeta, Annelida) are reported. Specimens were collected from 0 to 20m depths along Apulian coast (Mediterranean Sea). Species collected at shallowest depth showed the presence of microalgae and macroalgae fragments in their guts and were considered herbivores.

Reproduction of the Syllidae (Annelida: Polychaeta)
Hydrobiologia, 1999Polychaetes of the family Syllidae exhibit a remarkable diversity of reproductive phenomena. The primitive mode of sexual reproduction is characterized by epitoky (as epigamy and stolonization, respectively), swarming and external fertilization. Deviations from the primitive type, particularly evident in meiofaunal species, include external brooding ...

Is Syllis gracilis (Polychaeta: Syllidae) a species complex? An allozyme perspective
Marine Biology, 2000The genetic relationships between morphologically indistinguishable marine and brackish populations of Syllis gracilis Grube, 1840 (Polychaeta: Syllidae) were studied by means of allozyme electrophoresis. Samples of S. gracilis from marine coastal and brackish-water habitats were examined for variation at 13 presumptive loci.

Comparative Study of Pygidial Organization in Polychaetes of the Families Nephtyidae and Syllidae
Doklady Biological Sciences, 2018The first comparative study of the polychaete pygidial region has been performed using confocal scanning microscopy and immunohistochemical methods. Fundamentally new data has been obtained on the pygidial organization in representatives the Nephtyidae and Syllidae families. Despite differences in the overall morphology of pygidium, it is characterized

A new species of Opisthosyllis (Polychaeta: Syllidae) from California (U.S.A.)
Zootaxa, 2005Opisthosyllis leslieharrisae n. sp. is described from Santa Catalina Island, California. It differs from all other species of the genus in the following characters: dorsum densely covered by papillae in two sizes, and a distinct colour pattern consisting of white spots distributed transversally along the segments (only seen in live specimens) and dark ...

Revisited Syllidae of the English Channel coarse sediment communities
Journal of the Marine Biological Association of the United Kingdom, 2017Among the polychaetes, the Syllidae comprise numerous species whose study over many years has benefitted from valuable revisions and descriptions of new species in Europe. This abundant literature proves very useful for revisiting the taxonomy and distribution of the Syllidae in the English Channel (EC), mainly as regards existing studies on coarse ...

Faunistic analysis of Syllidae (Annelida: Polychaeta) from the Aegean Sea
2002A faunistic analysis of a total of 121 benthic samples collected from 31 stations in the infralittoral zone of the Aegean Sea, on various substrata and at various depths, yielded a total of 90 syllid species (18957 individuals). Four species are newly reported for the Mediterranean fauna and 27 species for the Eastern Mediterranean.

A new genus of Syllidae (Polychaeta) from Western Australia
Hydrobiologia, 2003During a study carried out on the subfamily Exogoninae (Syllidae) from Australia, several specimens of a new genus and species were found in samples of dead coral substrate from Western Australia. They have long palps, fused except for a terminal notch, long median and two short lateral antennae, a single pair of short tentacular cirri, and short ...

Syllidae (Polychaeta) from the Arctic and sub-Arctic regions
Journal of the Marine Biological Association of the United Kingdom, 2010A collection of over one hundred specimens of Syllidae (Polychaeta) from the Arctic and sub-Arctic regions has been examined and identified. The specimens were obtained from 26 stations in the Barents Sea, some Norwegian fiords and localities of the northern North Sea. A total of 21 species were identified; three species (Myrianida langerhansi (Gidholm,
