It's time to wrap up our study of Gnathifera, and this means investigating phylum Rotifera. These are the wheel animals, and we will need a few tutorials to get through them all. Some species are freeliving and some are parasitic, and you've probably had some in your body, since they're pretty much everywhere. Let's go over some general characteristics of this phylum now.
