This global polychaete data were selectively extracted from the Global Biodiversity Information Facility (GBIF) and the Ocean Biogeographic Information System (OBIS). Additionally, we also added the published
checklist of Indonesian polychaete species by Pamungkas and Glasby (2019). The data were used in the paper 'Biogeography of polychaete (Annelida) worms of the world'.
