Certainly oil pollution is a threat for the natural balance of ecosystems. The pollution sources are very different as well as their determinants. Depollution methods in case of oil pollution caused by tanker collisions are physical and chemical. This process induced by bacteria has a big disadvantage: biodegradation time is too long. The accidental oil spills affect biodiversity of aquatic and terrestrial ecosystems. The immediate consequences of oil pollution could be directly monitored using inventory of invertebrates. The test of the role played by ciliates in oil biodegradation process was made based on an interesting experiment performed on a small beach located in Constanta, Romania; The taxonomical aspects were completed by ecological aspects; the study is based on a complex geological analysis about the granulometry of beach sediments; the sands from Cazino Constanta beach are mainly represented by coarse and very coarse sand while gravels range from fine and very fine. During the experiment when performing the 48 hour control after adding the oil pollutant 13 ciliate forms were identified alive in the sand sample from Navodari station, their evolution being different.
