While the turtles are on land, scientists measure their shells. They also count eggs, record the nest temperatures, and attach radio transmitters to track where the turtles go. Find out more about Activities. The eggs look like billiard balls. Their shells are soft and leathery.
Scientists move nests that are too close to the water to safer areas or to hatcheries.
Find out more about Eggs. The eggs hatch in about two months. Scientists can tell if the hatchlings will be male or female by the temperature of the nest. Colder temperatures produce males. Warmer temperatures produce females.
