Nest Checking

A lot of the work at Playa Grande focuses on the leatherback sea turtles and their nesting habits. Leatherbacks come ashore at night and dig deep nests in the sand with their flippers. They lay eggs and then cover the eggs back up with sand. After that, the mommy turtles go back into the ocean, leaving the eggs to develop and hatch on their own.

From that, they can figure out how many hatched and what happened to the eggs that did not hatch. Some eggs die shortly after they are laid, and some die shortly before the hatchlings come out. No one knows why yet.

Then something very exciting happened! We found a hatchling!
