Editing Rotifer (section)

===Biology===
The coronal [[cilia]] pull the animal, when unattached, through the water.

Like many other microscopic animals, adult rotifers frequently exhibit [[eutely]]—they have a fixed number of [[cell (biology)|cell]]s within a species, usually on the order of 1,000.

Bdelloid rotifer genomes contain two or more divergent copies of each [[gene]], suggesting a long-term asexual [[evolution]]ary history.<ref>{{cite journal |author= Jessica L. Mark Welch, David B.
