Bdelloidea / ˈdɛlɔɪdiə / (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'), [1] distinguished from each other mainly on the basis of morphology. [2]

Although rotifers typically only live in freshwater environments, bdelloidea tend to live in brackish and even marine environments. They’re extremely resilient, even being able to survive radiation and drying out. In fact, drying out can help them to survive.

Bdelloids are characterized by having paired ovaries with vitellaria, more than two pedal glands, and ramate trophi. Most bdelloids are microphagous with a corona of either two trochal disks or a modified ciliated field.

Bdelloid rotifers are one of the strangest of all animals. Uniquely, these small, freshwater invertebrates reproduce entirely asexually and have avoided sex for some 80 million years. At …

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'), distinguished from each other mainly on the basis of morphology.

Bdelloid rotifers are a group of microscopic invertebrates known for their obligate parthenogenesis and exceptional resistance to extreme environments. Their diversity and distributions are poorly studied in Asia, especially in China.

Jan 1, 2004 · The order Bdelloidea consists of three families Habrotrochidae, Adinetidae and Philodinidae. Bdelloid rotifers were inhabiting on the bottom of lotic and lentic waters (Fontaneto and Ricci, 2004).
