Figure 8

The sea surface currents in the Eastern Mediterranean Sea. The pink arrows represent the currents probably responsible for the expansion of the Lessepsian molluscs and the blue thinning zone shows the probable pathway of that expansion from the Suez Canal towards north up to the NW Aegean Sea. Heavy ink arrows indicate the main pathway and the light ones a secondary pathway. Reconstructed map for the currents according to Robinson et al. [42], Olson et al. [43], Sayin et al.[44] and Poulain et al.[45].
