| In most species, the head carries a corona of cilia that draws a vortex of water into the mouth, which the rotifer sifts for food. |
| I always thought Bdelloid rotifer, which are microscopic mites, was a cool name. |
| On one occasion a glimpse was caught of a rotifer similar in shape to the common wheel animalcule, but with a yellow inside. |
| The changes of form in this rotifer are still more remarkable than in the common wheel-bearer. |
| This rotifer goes through another performance which I also believe to be simply a pastime. |
| Each rotifer in the colony moves its cilia, creating a current that brings food to the colony and assists in its locomotion. |
