The Turbellarian Taxonomic Database covers all turbellarian flatworms, including parasitic turbellarians.
The Turbellarian Taxonomic Database is one of the External Global Species Databases linked to WoRMS. Its content was used to create the original Turbellarian species list within WoRMS. Later on, the Research Group Biodiversity, Phylogeny and Population Studies of the University of Hasselt has developed the World Database of Proseriata and Kalyptorhynchia.
