Bdelloidea /ˈdɛlɔɪdiə/ (Greek βδελλα, bdella, "leech-like") is a class of rotifers found in freshwater habitats all over the world.

The main characteristics that distinguish bdelloids from related groups of rotifers are exclusively parthenogenetic reproduction and the ability to survive in dry, harsh environments by entering a state of desiccation-induced dormancy (anhydrobiosis) at any life stage....
