The authors demonstrate the probable immigration and stable settling of the pycnogonid Ammothea hilgendorfi (Böhm, 1879) at one station in the lagoon of Venice. The species is widely distributed naturally on both sides of the Pacific Ocean and has probably immigrated on ship hulls through the Suez Canal to the Mediterranean. Two more cases (the pycnogonid Anoplodactylus portus and the amphipod Elasmopus pectenicrus) of adventitious species in this sea are compared.
