Biological invasions can have major impacts on freshwater and marine ecosystems. Therefore, it is vital that non-indigenous species are accurately identified reported when potential or confirmed occur. The present study reports the first occurrence of Marenzelleria neglecta (Annelida, Spionidae) spread Laonome xeprovala Sabellidae) in Danube Delta–Black Sea ecosystem. Spionidae one most diverse...

As a result of processing materials from the expeditions Saint-Petersburg State University in 2012–2013 and Transarctic expedition 2019, 131 polychaete taxa were recorded, which 124 identified to species. On basis data previous recent collections, general list polychaetes Kara Sea was updated; it includes 209 species belonging 98 genera, 37 families, 15 orders. The following are reported for fi...

Spiralian development is characterized by the conservation of spindle orientation and cell geometry during early cleavage stages, as well as features of the ultimate fates of identified cells. This complex set of characters is shared by a number of animal lineages including nemerteans, polyclad platyhelminthes, annelids and mollusks. How a similar, highly stereotypical cleavage program can give...

Introduction Sustainable growth of the salmon aquaculture industry is highly dependent on availability new feed resources as well improved management and utilization waste streams from production. Polychaetes are capable recapturing recycling valuable biomolecules contained in sludge at same time constitute a possible resource for aquafeeds. Material methods In this study, potential Hediste div...

•Among the Lepidonotinae, two species of Lepidonotus are referred to new genera: L. dictyolepis Haswell, from Australia, to Augenerilepidonotus, and L. kumari Rullier, from Malaya, to Olgalepidonotus. As part of an on-going study on the polynoid polychaetes, two species that were described under Lepidonotus Leach, 1816, L. dictyolepis Haswell, 1883, from Australia, and L. kumari Rullier, 1970, ...

In less intensive shrimp culture systems, polychaetes are known to be a major food item of several penaeid species. Under these conditions, very little is known about their population dynamics and the possible interactions with penaeid predation and artificial feeding. This work examined the effects of Penaeus subtilis, predation, stocking density and supplemental feeding on the population dyna...

This Special Volume of Zootaxa has had a long gestation! Way back in 2011, Pat Hutchings was approached by Anne Hoggett, one of the Co-Directors of Lizard Island Research Station which is a facility of the Australian Museum, with the concept of running a polychaete workshop at Lizard Island. Back in 2005, the first Lizard Island taxonomic workshop investigating biodiversity of amphipod crustace...
