A series of cladistic analyses assesses the status and membership of the taxon Polychaeta.
The available literature, and a review by Fauchald & Rouse (1997), on the 80 accepted …

The typical sperm is comprised of a head, midpiece and flagellum. Around this theme there
is an enormous diversity of form–giant sperm, multi-flagellate sperm and also sperm that …

In this paper, we first demonstrate the historical background for the current unsatisfactory
state of systematics of the polychaetes. We then briefly discuss our knowledge of internal …

We present parsimony analyses of annelids based on the largest taxon sample and most
extensive molecular data set yet assembled, with two nuclear ribosomal genes (18S rDNA …

Syllidae is one of the most species‐rich groups within Annelida, with a wide variety of
reproductive modes and different regenerative processes. Syllids have striking ability to …

Abstract 'Trochophore'is a term used in a strict sense for larvae having an opposed-band
method of feeding, involving a prototroch and metatroch. Other ciliary bands such as a …

A phylogenetic analysis was conducted of the Nereidinae—those members of the
Nereididae (Polychaeta) with pharyngeal paragnaths. We had two objectives: to test the …

A cladistic analysis and taxonomic revision of the Namanereidinae (Nereididae: Polychaeta)
is presented. The cladistic analysis utilising 39 morphological characters (76 apomorphic …

The aim of this paper is to assess the monophyly of the Annelida. Also, recent cladistic
analyses of metazoan taxa, using a variety of data, have shown incongruities with regards to …

A large, combined phylogenetic analysis (including morphological and molecular data from
18S rDNA, 16S rDNA and cytochrome c oxidase subunit I), with the highest number of …
