Siboglinids are tube-dwelling annelids that are important members of deep-sea
chemosynthetic communities, which include hydrothermal vents, cold seeps, whale falls and …

In Plato's Phaedrus, Socrates is concerned with how things are grouped together and how
they are divided. He makes an analogy with carving up an animal. Just as cuts of meat …

Background A median, segmented, annelid nerve cord has repeatedly been compared to
the arthropod and vertebrate nerve cords and became the most used textbook …

Two enigmatic groups of morphologically simple parasites of invertebrates, the Dicyemida
(syn. Rhombozoa) and the Orthonectida, since the 19th century have been usually …

Meiofaunal life forms are found all over the animal tree of life, and miniaturization seems to
have occurred within otherwise macrofaunal clades multiple times. While sponges, comb …

The interstitial environment of marine sandy bottoms is a nutrient-rich, sheltered habitat
whilst at the same time also often a turbulent, space-limited, and ecologically challenging …

Osedax are gutless siboglinid worms that thrive on vertebrate bones lying on the ocean
floor, mainly those of whales. The posterior body of female Osedax penetrates into the bone …

Orthonectida is a small group of parasites, which, according to recent studies, may be
phylogenetically close to Annelida. Here, we describe the musculature and serotonin‐like …

We incorporate DNA sequences from a comprehensive sampling of taxa to provide an
updated phylogeny of Osedax and discuss the remarkable diversity of this clade of …

Most species of the bone-devouring marine annelid, Osedax, display distinct sexual
dimorphism with macroscopic sedentary females rooted in bones and free-living …
