Caulerpa a grappoli Caulerpa racemosa alga algae intotheblue.it
Caulerpa Racemosa is a green alga from the Caulerpaceae family. It is native to the Red Sea, but it is an allochthonous species of the Mediterranean Sea, where it has penetrated through the Suez Canal and where it has easily adapted. In the Mediterranean, together with Caulerpa Taxifolia, it is threatening the Posidonia Oceanica meadows of which it is a strong competitor.
We found it in a stretch of cliff on the Livorno coast: since Livorno is an important port of the Mediterranean it is easy to imagine that it arrived there through the ballast waters of ships.
