Abstract

The spatial variability of the body size and morphological structures of the planktonic copepod Oithona similis in the White Sea was studied. From north to south, there was a tendency for the male cephalothorax length to decrease. In moving from the central to the northern part of the sea and from the eastern to the western part, the relative antennule length in both sexes increased. The average body size of copepods was positively and the absolute (and relative) lengths of the antennules were negatively correlated with water salinity. The morphological variations have adaptive significance and are determined by environmental factors.
