Bdelloidea / ˈ d ɛ l ɔɪ d i ə / (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]

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.

Bdelloidea Rotifer (Philodina) This animation was created to show the way rotifers move, as well as display the struggles of drawing a live organism. Rotifers are zooplankton that inhabit a variety freshwater habitats, both stationary and flowing, as well as many other things such as moist soil, mosses, gutters, sewers, and many more.
