The aim of a World Register of Marine Species (WoRMS) is to provide an authoritative and comprehensive list of names of marine organisms, including information on synonymy. While the highest priority goes to valid names, other names in use are included so that this register can serve as a guide to interpret taxonomic literature.
The content of WoRMS is controlled by taxonomic and thematic experts, not by database managers. WoRMS has an editorial management system where each taxonomic group is represented by an expert who has the authority over the content, and is responsible for controlling the quality of the information. Each of these main taxonomic editors can invite several specialists of smaller groups within their area of responsibility to join them.
This register of marine species grew out of the European Register of Marine Species (ERMS), and its combination with several other species registers maintained at the Flanders Marine Institute (VLIZ). Rather than building separate registers for all projects, and to make sure taxonomy used in these different projects is consistent, VLIZ developed a consolidated database called ‘Aphia’. A list of marine species registers included in Aphia is available here. MarineSpecies.org is the web interface for the marine taxa available in this Aphia database. WoRMS combines information from Aphia with other authoritative marine species lists which are maintained by others (e.g. AlgaeBase, FishBase), the so-called 'externally hosted and managed species databases'.
Resources to build MarineSpecies.org and Aphia were provided mainly by the EU Network of Excellence ‘Marine Biodiversity and Ecosystem Functioning’ (MarBEF), and also by the EU funded Species 2000 Europe and ERMS projects. Aphia contains valid species names, synonyms and vernacular names, and extra information such as literature and biogeographic data. Besides species names, Aphia also contains the higher classification in which each scientific name is linked to its parent taxon. The classification used is a ‘compromise’ between established systems and recent changes. Its aim is to aid data management, rather than suggest any taxonomic or phylogenetic opinion on species relationships.
Keeping WoRMS up-to-date is a continuous process. New information is entered daily by the taxonomic editors and by the members of our data management team. Often data also come in from contributions of large datasets, such as global or regional species lists. No database of this size is without errors and omissions. We can’t promise to make no errors, but we do promise to follow up and give feedback on any communications pointing out errors. Feedback is very welcome!
222,176 accepted species; of which 211,241 checked (95%) 402,947 species names including synonyms 503,993 taxon names (infraspecies to kingdoms) 48,370 images; of which 23,442 checked (48%) WoRMS passed the 200,000 species mark in 2010 in conjunction with the celebration of 10 years' Census of Marine Life. Given an estimated 230,000 accepted described marine species, still 7,824 to go (plus the yearly increment of 2,000 newly described species). With WoRMS we aim to provide the most authoritative list of names of all marine species globally, ever published. WoRMS is a contribution to the Catalogue of Life, the Encyclopedia of Life, the Global Biodiversity Information Facility and the Census of Marine Life.
