| Abstract |
One hundred years has passed since one of the biggest biogeographical experiments started with the opening of the Suez Canal. The successful migration along the Canal of a great many Red Sea species into the Mediterranean is seen as a process to which most of these species were preadapted in the littoral environment of the Red Sea. The repeated transgressions of this sea into the basin of the Bitter Lakes and the existence—presently and in the past—of several slightly hypersaline lagoons along its shores, resulted in the creation of a special stock of species able to perform this migration. Progress through the Canal is either a step-by-step one, or a result of active swimming (or transport). Neither the role of planktonic spread by means of larvae and/or currents, nor the obstacles put by the salinity, should be overemphasized. The main factors in helping or hindering migration are considered to be the presence of suitable substrates and water transparencies in the Canal. |
