Global diversity of nemerteans (Nemertea) in freshwater

  • Per Sundberg

Freshwater Animal Diversity Assessment


Most ribborn worms (phylum Nemertea) are marine and only 22 of the currently named around 1,200 species are known from freshwater habitats (mainly lakes/ponds). They are all free-living benthic forms found in all continents except Antarctica. The vast majority of species have been recorded from the Palearctic region, but this may reflect sampling efforts rather than biogeography.
