The soft-shelled, white eggs of green turtles take 30-90 days to incubate, taking longer in wet seasons.
Female green turtles lay white, soft-shelled eggs that measure 35-58 millimeters in diameter. One female can lay 1-9 clutches in a single nesting season, but tends to average around 3. Each of these clutches can include 75-200 eggs.
Incubation takes 30-90 days, depending on whether or not it is the wet or dry season. Incubation typically takes longer in the wet season.
