Agardh were performed to test the hypothesis that boat transportation could explain its rapid and wide spreading along the Mediterranean coasts. In particular, studies were made of its desiccation resistance, drought tolerance, and survival capacity under simulated conditions prevailing in boat anchor lockers or in fishing net heaps. For comparative purposes, identical studies have been carried out with Caulerpa prolifera (Forsk l) Lamouroux. Dehydration rates were very similar for both species, with lost of 50% of their original relative water content in 1 h, at 23 °C temperature and 70-75% of relative air humidity, and complete desiccation in 5 h. Rehydralion of plants with different degrees of dehydration was also very rapid but not always complete; thalli of Caulerpa TI - The Spreading of the Introduced Seaweed Caulerpa taxifolia (Vahl) C.
