I ask Beluot. Statistically, only one to three percent, he tells me. Maybe of 10,000, about 150 will make it to adulthood. Eggs in natural nests face many threats to survival. Predators like monitor lizards dig up the nests for easy meals.
Ants also prey on turtle eggs.
Eggs may be accidentally destroyed by turtles digging new nests, and on some beaches nests may be swamped by high tides. But most eggs left undisturbed will hatch. Each turtle's heroic battle for survival begins as soon as it scrabbles through the roof of its nest. They only catch the slower, weaker ones. And any that come out in the daytime might be eaten by kites or eagles.
