Collotheca (coll-o-thee-ka) is a rotifer (metazoa) and is fairly distinctive because of the long stiff setae. The organism may contract. Rotifers are common members of the microbial communities of many aquatic ecosystems. Although they are multiceullar animals, they may be only be 100 microns long, and so overlap in size with ciliates. They can be confused with ciliates because they use cilia to capture their food. However, they can be distinguished because they have an exoskeleton, usually two posterior toes, and a tough pharyngeal region just behind the head.

Collotheca (col-owe-theek-a) a rotifer, with long cilia used to capture food. Contractile, and with its anterior ciliary organ, the corona, developed into 5 lobes. Often also with mucus around the stalk, but this is not evident here. Phase contrast.
