This study assessed jaguar predation impact on three species of marine turtles(Chelonia mydas,Dermochelys coriaceaandEretmochelys imbricata) that nest in Tortuguero beach. Jaguarpredation data was obtained by using two methodologies, literature review (historical records prior the year2005) and weekly surveys along the 29 km stretch of beach during the period 2005-2013. Our results indicatedthat jaguar predation has increased from one marine turtle in 1981 to 198 in 2013. Jaguars consumed annuallyan average of 120 (SD= 45) and 2 (SD= 3) green turtles and leatherbacks in Tortuguero beach, respectively.Based on our results we concluded that jaguars do not represent a threat to the population of green turtles thatnest in Tortuguero beach, and it is not the main cause for population decline for leatherbacks and hawksbills.Future research should focus on continuing to monitor this predator-prey relationship as well as the factors thatinfluence it so the proper management decisions can be taken.
