Bdelloidea Rotifera

From Wikipedia: "Bdelloidea /ˈdɛlɔɪdiə/ (Greek βδελλα, bdella, "leech-like") is a class of rotifers found in freshwater habitats all over the world. There are over 450 described species of bdelloid rotifers (or 'bdelloids'),[1] distinguished from each other mainly on the basis of morphology.[2] 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.[3] They are often referred to as "ancient asexuals" due to their unique asexual history that spans back to over 25 million years ago through fossil evidence.[4] Bdelloid rotifers are microscopic organisms, typically between 150 and 700 µm in length.[3] Most are slightly too small to be seen with the naked eye, but appear as tiny white dots through even a weak hand lens, especially in bright light."
