Abstract
Three years after the first record of Caulerpa racemosa at Meloria Sho als (Leghorn, Italy), a study has been undertaken in order to evaluate the growth of this species on different substratum and to investigate the interactions with different biocenosis. The results of this study have shown that C. racemosa has increased the colonized surface from 3000 m(2) in 1993 to 300 ha in 1997. Caulerpa racemosa grows on algal turfs or the Cymodocea nodosa bed. In the contact area with Posidonia oceanica the stolons stratify, covering the rhizomes of the phanerogam .
