Polychaeta Lana Crumrine
Polychaeta Lana Crumrine Well over 200 species of the class Polychaeta are found in waters off the shores of the Pacific Northwest. Larval descriptions are not available for the majority of these species, though descriptions are available of the larvae for at least some species from most families. This chapter provides a dichotomous key to the polychaete larvae to the family level for those families with known or suspected pelagic larva. Descriptions have be $in gleaned from the literature from sites worldwide, and the keys are based on the assumption that developmental patterns are similar in different geographical locations. This is a large assumption; there are cases in which development varies with geography (e.g., Levin, 1984). Identifying polychaetes at the trochophore stage can be difficult, and culturing larvae to advanced stages is advised by several experts in the field (Bhaud and Cazaux, 1987; Plate and Husemann, 1994). Reproduction, Development, and Morphology Within the polychaetes, the patterns of reproduction and larval development are quite variable. Sexes are separate in most species, though hermaphroditism is not uncommon. Some groups undergo a process called epitoky at sexual maturation; benthic adults develop swimming structures, internal organs degenerate, and mating occurs between adults swimming in the water column. Descriptions of reproductive pattern, gamete formation, and spawning can be found in Strathmann (1987). Larval polychaetes generally develop through three stages: the trochophore, metatrochophore, and nectochaete stages. Trochophores are ciliated larvae (see Fig. 1).A band of cilia, the prototroch, is used for locomotion and sometimes feeding. Trochophore larvae are generally broad anteriorly and taper posteriorly. -

Biodiversity Data Journal 3: e5737. doi: 10.3897/BDJ.3.e5737 Abstract Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all living European land and freshwater animals, their geographical distribution at country level (up to the Urals, excluding the Caucasus region), and some additional information. The Fauna Europaea project covers about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies, which is much more than the originally projected number of 100,000 species. This represents a huge effort by more than 400 contributing specialists throughout Europe and is a unique (standard) reference suitable for many users in science, government, industry, nature conservation and education. This paper provides updated information on the taxonomic composition and distribution of the Annelida - terrestrial Oligochaeta (Megadrili and Enchytraeidae), Aphanoneura and Polychaeta, recorded in Europe. Data on 18 families, 11 autochthonous and 7 allochthonous, represented in our continent by a total of 800 species, are reviewed, beginning from their distinctness, phylogenetic status, diversity and global distribution, and following with major recent developments in taxonomic and faunistic research in Europe. -

The traditionally recognized classes were Polychaeta, Oligochaeta and Hirudinea. The latter two are now viewed as the taxon Clitellata, since recognizing Hirudinea with class rank renders Oligochaeta paraphyletic. Polychaeta appears to contain Clitellata, and so may be synonymous with Annelida. Current consensus would place previously rec- ognized phyla such as Echiura, Pogonophora, Sipuncula and Vestimentifera as annelids, though relationships among these and the various other annelid lineages are still unresolved. Key words: Polychaeta, Oligochaeta, Clitellata, Echiura, Pogonophora, Vestimentifera, Sipuncula, phylogeny, review Introduction Annelida is a group commonly referred to as segmented worms, found worldwide in terrestrial, freshwater and marine habitats. The first annelids were formally named by Linnaeus, including well-known forms such as the earthworm Lumbricus terrestris Linnaeus, 1758, the medicinal leech Hirudo medicinalis Linnaeus, 1758, and the sea-mouse Aphrodite aculeata Linnaeus, 1758. -
Phylogenetics of Acrocirridae and Flabelligeridae (Cirratuliformia, Annelida)
Zoologica Scripta Phylogenetics of Acrocirridae and Flabelligeridae (Cirratuliformia, Annelida) KAREN J. OSBORN &GREG W. ROUSE Submitted: 26 July 2010 Osborn, K. J. & Rouse, G. W. (2010). Phylogenetics of Acrocirridae and Flabelligeridae Accepted: 5 October 2010 (Cirratuliformia, Annelida). — Zoologica Scripta, 40, 204–219. doi:10.1111/j.1463-6409.2010.00460.x When seven deep-sea, swimming cirratuliforms were recently discovered, the need for a thorough phylogenetic hypothesis for Cirratuliformia was clear. Here, we provide a robust phylogenetic hypothesis for the relationships within Acrocirridae and increase the taxon sampling and resolution within Flabelligeridae based on both molecular (18S, 28S, 16S, COI and CytB) and morphological data. Data partitions were analyzed separately and in combination. Acrocirridae and Flabelligeridae were reciprocally monophyletic sister groups when rooted by cirratulids. The seven recently discovered species form a clade within Acrocirridae and will be designated as four genera based on phylogenetic relationships and apomorphies. A revised diagnosis is provided for Swima, restricting the genus to three spe- cies distinguished by a thick gelatinous sheath, transparent body, simple nuchal organs, a single medial subulate branchia, and four pair of small segmental branchiae modified as elliptical, bioluminescent sacs. Helmetophorus and Chauvinelia are maintained as separate genera based on morphological differences. Evidence for flabelligerid branchiae being seg- mental is provided, the papillae on segment two of most acrocirrids is confirmed to be the nephridiopores, and scanning electron microscopy is used to examine acrocirrid spinous chaetae in comparison with flabelligerid segmented chaetae.

Abd-Elnaby National Institute of Oceanography and Fisheries, Alexandria, Egypt Abstract: Faunistic analysis of benthic samples were obtained during a trip to the south part of Suez Canal, Egypt, during April, 2007, which revealed the presence of 82 polychaete species, 18 of them are considered as new records for the Egyptian waters. In order to achieve this study fouling components and sediments samples were collected by Van Veen grab (0.5 to 8 m depths), from six stations extending from Deversoir to Port Toufiq. Illustrative taxonomical characters is provided for each newly recorded species; as well as geographic distribution are given to draw a picture of the new records, which indicated that most of them are lessepsian migrant and 6 species are of Mediterranean and Adriatic Sea affinity. Also the polychaete recorded formed less dense of population on shallow water, hard substrates and also in sediment.
