PycnoBase distribution details
Italian part of the Adriatic Sea (Marine Region) (origin: alien)
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. [...] Fouling panels measuring 200 x 300 mm were immersed in the tidal zone at Punta Salute, near one of the three entrances of the lagoon of Venice. The panels were regularly retrieved and inspected as part of a series of studies conducted in 1979-1981.
