Current knowledge of the starvation and reproduction stages of the limnic species Holophrya teres (Ciliophora: Prostomatea)

This study presents a light microscopy observation on the life cycle of the prostomatid ciliate, Holophrya teres. We were able to make distinctions between its reproduction and starvation phases. Within these phases, we observed the following stages, namely the trophont, protomont and tomont, as well as reproductive (tomites), temporary and resting cysts. Additionally, we also described two types of active specimens after the excystation...
