Considerations on the taxonomy of the Phylum Tardigrada

An analysis of the taxonomy of the Tardigrada is offered, based on the latest checklist version. A total of 1167 species from 113 genera were counted, but marine species are misrepresented on account of being understudied. Moreover, many poor descriptions and synonyms remain in this constantly growing list. We advocate more accurate future taxonomic work, aiming for an official list of species that better represents true values of biodiversity
