Notes
Descriptions are provided of the morphology, infraciliature, life cycle, and ecology of the freshwater ciliate Prorodon viridis. P. viridis is a prostomatid ciliate with endosymbiotic Chlorellae and with a cosmopolitan distribution. The ciliate lives close to the oxic-anoxic boundary in freshwater lakes and ponds worldwide, and it is able to survive in anoxic, dimly-lit deep waters. The O2-evolving endosymbionts -the zoochlorellae- probably sustain the aerobic respiration of the ciliate host. The vertical distribution of this species in natural oxygen gradients is described.
