    Abstract

    Translocation of radioactive 14C and 32P between the pyrgomatine barnacle Savignium milleporum and the hydrocoral Millepora dichotoma in the Red Sea was investigated in order to discover any mutual nutritional benefits. Translocation of photosynthetic products from endosymbiotic zooxanthellae to the hydrocoral was demonstrated. There was no evidence that carbon was further translocated to the barnacle. However, hydrocorals bearing barnacles accumulated significantly more 14C and 32P than those with no barnacles. The possibility that the hydrocorals recycle substances excreted by the barnacles is discussed in the context of the oligotrophic environment of the Red Sea.
