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.

These structures can provide predation refuges and increase larval settlement and thereby increase the richness and abundance of fauna. We collected invertebrate samples from an intertidal flat with low onuphid tube density (2.7 m–2) in Mozambique and document that more organisms (70 times higher mollusc abundances) and more species (15 times more mollusc species) were found associated with solitary tubes of an onuphid polychaete compared with surrounding sand habitats. These results are in agreement with tube versus sand comparisons from soft-bottom systems in the North Atlantic where polychaete tube densities are often much higher.

    Taxonomy and distribution of moonshine worms (Diopatra sp.) in Knysna Estuary by Hendré van Rensburg Thesis presented in fulfilment of the requirements for the degree of Master of Science in Zoology Department of Botany and Zoology Faculty of Science Stellenbosch University Supervisor: Prof. Carol Anne Simon Co-supervisor: Prof. Conrad Matthee December 2019 Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Copyright © 2019 Stellenbosch University All rights reserved i Stellenbosch University https://scholar.sun.ac.za Abstract Polychaetes as fish bait have become increasingly popular in the Knysna Estuary over the last decade. The presence of an unknown polychaete, Diopatra sp. was first reported in the Knysna Estuary ten years ago, when it was harvested as fish bait in small quantities by local fishermen who called it the moonshine worm. Since this very conspicuous species was not detected by intensive biodiversity sampling in the estuary in the 1950s and 1990s, it should thus be considered new to the estuary. A preliminary morphological investigation showed that Diopatra sp. may be Diopatra neapolitana (Delle Chiaje, 1841). However, D. neapolitana is a pseudo-cosmopolitan species with local distribution restricted to Durban and Port Elizabeth. As several cosmopolitan species have recently been described as cryptic endemic species, it is likely that Diopatra sp.

  • Diopatra Cuprea
    MARINE ECOLOGY PROGRESS SERIES Vol. 183: 169-178.1999 Published July 6 1 Mar Ecol Prog Ser l Distributions of total and active bacteria in biofilms lining tubes of the onuphid polychaete Diopatra cuprea Tina M. Phillips, Charles R. Lovell* Department of Biological Sciences, University of South Carolina, Columbia, South Carolina 29208, USA ABSTRACT: Infaunal burrows and tubes support elevated levels of microbial biomass and activities relative to the surrounding bulk sediments. The impacts of these structures on sediment biogeochem- istry have been intensively studled, but very little is known about the microbiota or their spatial orga- nization within these microenvironments. Distributions of bacterial cells and microcolonies and of potentially active bacterial cells in tubes of the onuphid polychaete Diopatra cuprea were determined using confocal scanning laser microscopy. Distributions were examined among different tubes, at dif- ferent locations within a tube, and at different depths in the biofilms lining these tubes. The average quantity of cells across all tubes examined was 5.61 X 10' cm-3 and there was no trend in the distribu- tion of cells along the length of the tube or with increasing depth in the biofilm. Cell size across all tubes collected in February 1997 averaged 0.085 pm3 but varied seasonally. Mean cell size increased with increasing depth below the sediment surface of the tube site sampled, and decreased with increasing depth in the biofilm. Microcolonies were abundant and not confined to specific depths within the biofh or locations within the tube. Potentially active cells were observed at all depths within the biofilm and at least 46% (mean = 68%) of cells at any given site were potentially active.

E-mail: [email protected] Abstract This study describes a new species of the genus Diopatra Audouin and Milne-Edwards, 1833. Diopatra micrura sp. nov., was found on the western and the southern coast of Portugal and can be distinguished from other Diopatra species by a characteristic striped colour pattern of the antennae and palps. Other diagnostic morphological characteristics include ventral parapodial lobes, crescentic nuchal organs, ceratophores with 12–15 rings, and subacicular hooks from chaetigers 8–13. This species was found mainly in fine or very fine sand with variable fines content, from the intertidal region up to 50 meters depth. Molecular studies of mitochondrial DNA genes 16S rDNA and COI confirmed the distinction of D. micrura sp. nov., from other European Diopatra species. The percentage of nucleotides divergence between the new species and D. neapolitana and D. marocensis was respectively 16% and 17% for COI and 12% and 15% for 16S. The nucleotide sequence for the 16S gene was always the same in all specimens of D. micrura and two haplotypes were found for the COI gene. The discovery of D. micrura sp. nov., brings the number of Diopatra species known from Portugal to three and from Europe to four; a key to the four species is provided.
