Abstract
On the basis of biometrical measurements of 11,000 individuals out of
10 samples collected at different depths, the quantitative parameters
that characterize Mytilaster lineatus specimens from the Romanian 
Black Sea shore and their tendency of growth were established. 
Mytilaster lineatus has a large morphological variability due to the
permanent and nonperiodical fluctuations of the ecological factors.
