The Tardigrada, or water bears, is a small phylum comprised of about 1,000 described species of microscopic animals found in almost all types of permanently or periodically moist habitats, including the soil, the deep sea, hot springs, glaciers, and mosses. Three known species are the eutardigrade Thulinia, the heterotardigrade Echiniscoides, and the parthenogenetic eutardigrade Hypsibius. Morphological studies generally recognise two orders, Heterotardigrada and Eutardigrada. Despite their seemingly unquestioned monophyly, the tardigrades have been associated with different groups, such as panartropods and cycloneuralians.
