Steranes preserved in sedimentary rocks serve as molecular fossils, which are thought to
record the expansion of eukaryote life through the Neoproterozoic Era (~ 1000-541 Ma) …

Annelid chaetae are extracellular chitinous structures that are formed in an extracellular
epidermal invagination, the chaetal follicle. The basalmost cell of this follicle, the …

Background The mitochondrial genomes (mitogenomes) of metazoans generally include the
same set of protein-coding genes, which ensures the homology of mitochondrial genes …

Historic species records of the families Onuphidae and Eunicidae, from the Falkland Islands
region, are reviewed and updated, new records added from intertidal and nearshore …

Lumbrineridae is a family of marine annelids with simple external morphology but complex
and diverse jaw apparatuses consisting of paired maxillae and mandibles. Here we present …

The Cambrian fossil Amiskwia sagittiformis has puzzled palaeontologists for more than a
century, but recent re-investigation of its morphology suggested a close relationship with the …

In this study, we conducted morphological and molecular analyses of Perinereis wilsoni, a
species being considered for aquaculture in China. We found this species difficult to identify …

Eunicida is a taxon of marine annelids currently comprising the taxa Eunicidae, Onuphidae,
Dorvilleidae, Oenonidae, Lumbrineridae, Histriobdellidae and Hartmaniella. Most …

Nuclear lamins are the main components of the nuclear lamina in many eukaryotes. They
are members of the intermediate filament (IF) protein family. Lamins differ from cytoplasmic …

Phylum Annelida are ubiquitous metazoans found in almost every terrestrial and aquatic
habitat on Earth. Historically, taxonomic studies on the phylum have been focussed largely …
