Ciliates have been exploited as useful and highly potential models for water quality fluctuations and toxicant influx. They have remained as models due to ubiquitous nature, speed of analysis, faster generation time, minimal epigenetic variability and genomic similarity to highest organism. These organisms have developed specialization of intracellular structures and functions, comparable what has occurred between the different cells of a multicellular organism. Depletion in the food vacuole formation and changes in the contractile vacuole activity highlighted the importance of Euplotes. The tests carried in this study are simple, fast and give overall information about the ecophysiological effects of delfin in response to toxicant influx.
