Sperm ultra-structure of Odontosyllis ctenostoma (Polychaeta: Syllidae) with inferences on syllid phylogeny and reproductive biology

open access: yesScientia Marina, 2008
The analysis of the complex reproductive patterns of Syllidae may drastically change the taxonomic hierarchy of the family. To further contribute to the knowledge of Syllidae we have described the sperm ultra-structure and some steps of spermiogenesis of

An integrative approach to the anatomy of Syllis gracilis Grube, 1840 (Annelida) using micro-computed X-ray tomography [PDF]

open access: yesPeerJ, 2019
Background The overall anatomy of the genus Syllis (Annelida: Syllidae) has been largely studied; however, an integrative approach considering different anatomical techniques has never been considered.

A micro‐CT approach to the anatomy of Pectinariidae Quatrefages, 1866 (Annelida)

open access: yesActa Zoologica, Volume 106, Issue 4, Page 463-484, October 2025.
Abstract The Micro‐computed X‐ray tomography (micro‐CT) technique is used to examine the external and internal anatomy of four species of Pectinariidae (Annelida: Terebellida): Amphictene auricoma, Cistenides granulata, Cistenides hyperborea and Lagis sp., from material collected off Iceland and NW Spain.

Evolution of Haplosyllis (Syllidae, Annelida) With Emphasis on the Indo‐Pacific Region and the djiboutiensis Species Complex

open access: yesZoologica Scripta, Volume 54, Issue 5, Page 684-707, September 2025.
ABSTRACT Haplosyllis is a worldwide distributed genus of marine annelids, commonly associated with other invertebrates. Its characteristic simple bidentate chaetae have often led to mistakes in estimating the real diversity of the genus. Currently, Haplosyllis includes 38 species, nearly half of which inhabit the Indo‐West Pacific (IPW).

From two segments and beyond: Investigating the onset of regeneration in Syllis malaquini

open access: yesEvolution &Development, Volume 26, Issue 6, November 2024.
This study shows that the segmented worm Syllis malaquini needs at least two segments to regenerate head and tail, with gut regions significantly influencing the success or failure of regeneration. Abstract Annelids feature a diverse range of regenerative abilities, but complete whole‐body regeneration is less common, particularly in the context of the

Field collections and environmental DNA surveys reveal topographic complexity of coral reefs as a predictor of cryptobenthic biodiversity across small spatial scales

open access: yesEnvironmental DNA, Volume 6, Issue 3, May–June 2024.
Ordination of the 14 sampling sites (numbers) using a non‐metric multidimensional scaling (NMDS) based on the Bray‐Curtis dissimilarities of the 13 microhabitats. This means the 14 sites are placed in respect to their similarity in microhabitats of which the six most abundant across sites are displayed in orange.
