Lizard Island Polychaete Workshop: sampling sites and a checklist of polychaetes
Zootaxa, 2015In August 2013, a two week polychaete workshop was held at Lizard Island, Great Barrier Reef. Twenty-one sites representing 121 collection events were sampled for polychetes around Lizard and on the Outer Barrier. Workshop participants sorted polychaetes to family and each participant received on loan selected families to work up.

Problems in polychaete systematics
Hydrobiologia, 2003Some of the intriguing issues in current polychaete systematics are reviewed. (1) The root of the ‘polychaete’ tree. Currently there are two major hypotheses concerning the root position among polychaetes. One is based on rooting cladograms with outgroups such as Mollusca and result in simple-bodied taxa such as Opheliidae and Questidae forming a basal

Polychaetes as environmental indicators revisited
Marine Pollution Bulletin, 2005The utilization of polychaetes in descriptive ecology is reviewed in the light of recent research especially concerning the biota hard bottom environments. Polychaetes, often linked in the past to the concept of opportunistic species able to proliferate after an increase in organic matter, have played an important role especially with regard to ...

Polychaete aquaculture and polychaete science: a mutual synergism
Hydrobiologia, 1999In 1984, the commercial aquaculture of the polychaete Nereis virens was initiated in NE England, at about the same time similar developments took place in the Netherlands, both establishing alternative sources of this animal as a means of supplying existing markets for marine worms to be used as bait by sea anglers.

Polychaete/amphipod ratio revisited
Marine Pollution Bulletin, 2007In this paper, we reexamine the opportunistic polychaete/amphipod ratio, modifying it to allow estuarine and coastal communities to be divided into the five classes suggested by the European Water Framework Directive (WFD). The resulting biological index, called the BOPA index, considers the total number of individuals collected in the samples, the ...

The Quarterly Review of Biology, 1971
It is suggested that, because of their relatively simple repertoires of behavior, polychaetes may be particularly useful in behavioral research. An interesting range of responses has already been described in these animals, including those involved in habitat selection, feeding, tube construction, escape from predators, fighting, pairing, swarming ...

Proceedings / Indian Academy of Sciences, 1949
1. A detailed study of the eyes of a few common polychaetes of Madras with different habits has been carried out giving a brief comparison of their structure with that of allied forms from European waters. 2. The eye in Eunicidae is usually composed of a retinal cup and a central refractive body which consists of a localised thickening ...

Larval settlement of polychaetes
Hydrobiologia, 1999Many benthic marine invertebrate species have a dispersive larval stage in their life histories. Larvae typically spend hours, weeks, or months developing in plankton before they become competent to settle and metamorphose. Recruitment to benthic populations depends on the numbers of competent larvae transported to sites and/or the interaction between ...

Muscular system in polychaetes (Annelida) [PDF]
The structure of the polychaete muscular system is reviewed. The muscular system comprises the muscles of the body wall, the musculature of the parapodial complex and the muscle system of the dissepiments and mesenteries. Various types of organisation of the longitudinal and circular components of the muscular body wall are distinguished. In Opheliidae,

A census of abyssal polychaetes
Deep Sea Research Part II: Topical Studies in Oceanography, 2009Abstract As part of the Census of Marine Life's programme of summarising existing knowledge of the oceans, records of all polychaete species collected below 2000 m have been collated from the literature. A total of 3633 records was assembled into a database, revealing that 768 species, 358 of which were new to science, have been reported from the ...
