Annelida is an ecologically and morphologically diverse phylum within the Lophotrochozoa
whose members occupy a wide range of environments and show diverse life styles. The …

The Cambrian 'explosion'is widely regarded as one of the fulcrum points in the history of life,
yet its origins and causes remain deeply controversial. New data from the fossil record …

The study of ecosystem functioning–the role which organisms play in an ecosystem–is
becoming increasingly important in marine ecological research. The functional structure of a …

Clitellata, with more than one third of all annelid species described, is briefly introduced, and
an overview of the hypotheses of phylogenetic relationships among the groups traditionally …

The phylogenetic position of Annelida within Metazoa was uncontroversial for a long time.
Ever since Cuvier (1817), the dominant hypothesis was the Articulata hypothesis, which …

Pogonophora, also known as Siboglinidae, are tube-dwelling marine annelids. They rely on
endosymbiotic chemoautotrophic bacteria for nutrition and their anatomy and physiology are …

Background The last annotated checklist of marine polychaetes in Greece was published in
2001. Since then, global taxonomic progress, combined with many new species records for …

Two conflicting hypotheses of protostome relationships, Articulata and Ecdysozoa, are
reviewed by evaluating the evidence in favor and against each one of them. Understanding …

Background Paired mushroom bodies, an unpaired central complex, and bilaterally
arranged clusters of olfactory glomeruli are among the most distinctive components of …

The use of Micro-computed X-ray tomography (microCT or μCT) in the study of the anatomy
of Annelids is becoming more common. Here we present a new approach to the anatomical …
