Six hundred and eighty alien marine multicellular species have been recorded in the Mediterranean Sea, with many establishing viable populations and dispersing along its coastline. A brief history of bioinvasions research in the Mediterranean Sea is presented. Particular attention is paid to gelatinous invasive species: the temporal and spatial spread of four alien scyphozoans and two alien ctenophores is outlined. We highlight few of the discernible, and sometimes dramatic, physical alterations to habitats associated with invasive aliens in the Mediterranean littoral, as well as food web interactions of alien and native fish. The propagule pressure driving the Erythraean invasion is powerful in the establishment and spread of alien species in the eastern and central Mediterranean. The implications of the enlargement of Suez Canal, reflecting patterns in global trade and economy, are briefly discussed.
