This page is a higher classification overview of freshwater, non-parasite, non-insect, invertebrate animal diversity.

Traditionally, the subject of zoology has been partitioned among various specialties: the vertebrate classes (ichthyology, herpetology, ornithology, and mammalogy), insects and other terrestrial arthropods (entomology), parasites (parasitology), and everything else (invertebrate zoology). The WInvertebrates project is aimed in particular at the freshwater taxa of the “everything else” group. Some parasites belonging to otherwise free-living taxa are also included, as well as terrestrial representatives of non-arthropod invertebrate phyla.

Bilaterial eumetazoans in general are divided among two superphyla: Protostomia and Deuterostomia. With the exceptions of two species in the phylum Xenacoelomorpha, the freshwater invertebrate phyla are classified in the former.
