   Nyckelord :Polychaeta; Phyllodocidae; Alciopidae; pelagic polychaetes; phylogeny; cryptic species;

   Sammanfattning : Polychaetes are a large group of segmented worms that display an enormous morphological diversity. Molecular data has shown in recent years that groups previously thought to be separate from polychaetes are actually part of the group. LÄS MER

3. 2. Early Palaeozoic jawed polychaetes with focus on polychaetaspids and ramphoprionids from the Silurian of Gotland, Sweden
