Resumen: Settlement of Caribbean coral planule with and without zooxanthellae was followed in response to four different settlement enviroments; one harboring zooxanthellae, one harboring crustose corralline algae and one containing zooxanthellae and CCA. Aposymbiotic planulae of Montastraea faveolata settled preferably in both enviroments where zooxanthellae were present. Planulae of Agaricia humilis, tghat already possessed zooxanthellae through maternal inheritance, showed no preference for either settlement enviroment. These results suggest that planulae thart lack zooxanthellae actively respond to the presence of zooxanthellae upon settlement and preferably settle in areas where zooxanthellae are present. Early succesful cquisition of symbionts likely enhances rrecruitment success as symbionts provide the settler with additional resources to increase survival probabilities and enhance early growth.
