Abstract
The ascidian Phallusia nigra is listed among the non-indigenous species of the Mediterranean Sea and its first occurrence in Hellenic waters is noted here. The westward expansion of the black sea squirt from the north Levantine coast, up to the Aegean Sea has been revealed by scuba diving, as established populations were recorded offshore and in one of the harbours of Rhodes Island. Maintenance conditions of the species in captivity are briefly discussed.
Highlights
Alien species continuously increase in numbers in the Mediterranean waters (Zenetos 2010)
Populations of Phallusia nigra Savigny, 1816 (Ascidiidae) have been revealed for the first time on natural and artificial substrates of Rhodes Island, increasing the number of alien species established in the region
Among the eleven species of the family Ascidiidae occurring in the Mediterranean Sea (Monniot and Monniot 1987; Koukouras et al 1995), two are considered non-indigenous, namely Ascidia cannelata Oken, 1820 and Phallusia nigra (Zenetos et al 2005; IzquierdoMuñoz et al 2009; Shenkar and Loya 2009)
