It has long been established that incubation temperature plays a major role in the sexual differentiation of sea turtles, with higher temperatures resulting in a greater ration of female hatchlings. However, apart from ambient temperature, metabolic heating within the nest may also potentially influence the incubation temperature of turtle nests.  This study aims to provide a deeper insight into this phenomenon, by assessing the duration of metabolic heating events throughout the incubation period and determine the effects of clutch size on metabolic heating
