Abstract 
On the basis of the observations and of the samples collected over 
the 1962-1969 in 11 localities from the Romanian Black Sea littoral,
in the paper both, the distribution and the ecology of 71 species of 
psamobionte ciliates are given. Ecological data refer primary to the 
influence of the sand granulometry on the specific composition, esta-
blishing the ratio the micro-, mezo - and euryporal species from va-
ried localities. Then, the effect of temperature salinity and feeding
factor on the psammobionte ciliates are disscused. Also, the place of 
ciliates in the trophic web of the benthos and their role in the 
marine sand ecosystem are presented.
