As the names suggest, the subdivision of annelids into the Errantia and Sedentaria matches their overall lifestyles (Fig. 1). Members of the Errantia are free to move about, and crawl, swim or burrow.

The Leibniz Association is funding a new collaborative project to untangle European marine annelids. Led by Dr Jenna Moore at the Leibniz Institute for the Analysis of Biodiversity Change (LIB), the ...

A new species of ancient sea worm with an impressively elaborate set of star-shaped chaetae has been discovered after its puzzling fossilized form was found to be animal not mineral. And just as ...

A new genetic analysis of a large group of ringed worms called annelids proves a 150-year-old hypothesis that these many species can be split into the lazy bums and the jocks. The annelids, which ...

Recent molecular phylogenetic analysis has shown that the marine animals known as peanut worms are not a separate phylum, but are definitely part of the family of annelids, also known as segmented ...

In an article published in the journal Nature Communications, scientists reveal that the regeneration processes in a marine worm, the annelid worm, show similarities to those observed in certain ...

The demand for rare raw materials, such as cobalt, is fuelling the exploration of the deep-sea floor for mining. Commercial deep-sea mining is currently prohibited in areas beyond national ...

Excavations by a University of Kansas paleontologist working in a treasure trove of fossils called the "Spence Shale Lagerstätte" have revealed an ancient sea worm unknown to science until now. The ...

A new interdisciplinary study led by molecular biologist Florian Raible from the Max Perutz Labs at the University of Vienna provides exciting insights into the bristles of the marine annelid worm ...

Ancient fossils have shed new light on a type of sea worm linking it to the time of an evolutionary explosion that gave rise to modern animal life. Researchers at Durham University, UK, and Northwest ...
