Bdelloidea

Bdelloidea (from Greek βδέλλα, bdella 'leech') is a class of rotifers found in freshwater habitats all over the world. There are over 450 described species of bdelloid rotifers (or 'bdelloids'), distinguished from each other mainly on the basis of morphology. 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. They are often referred to as "ancient asexuals" due to their unique a

Adineta is a genus of rotifers belonging to the family Adinetidae. Species of this genus are found in Europe, Northern America, Australia and southernmost parts of the Southern Hemisphere.

Rotaria is a genus of asexual, microscopic animal known as a bdelloid rotifer. Analysis published in 2007 of morphology and DNA sequence data of species from the genus confirmed that despite their asexual mechanism of reproduction, two fundamental properties of species, independent evolution and ecological divergence by natural selection occurred. This demonstrates that sex is not a necessary condition for speciation.
