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

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 ...

Researchers have described an exceptionally well-preserved new fossil species of bristle worm called Kootenayscolex barbarensis. Discovered from the 508-million-year-old Marble Canyon fossil site in ...

Scientists have discovered the oldest fossil that can be assigned to the living annelid worms, the group of animals that contains earthworms, leeches and many different forms in the ocean including ...

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.

Larvae of a marine ragworm Platynereis dumerilii have been studied as a zooplankton model, and possess photoreceptor cells in the brain to regulate circadian swimming behavior. This study revealed ...
