Santa Maria Tonameca, MEXICO -- Some 400,000 Olive Ridley turtles have been arriving on a Mexican beach to lay eggs.
Each giant sea turtle lays between 80 and 150 eggs and only 60 to 70 percent of the hatchlings reach the sea and survive.
Vigilant turtle watchers have taken up guard along the beach and say this year's migration is going smoothly.
For the past ten years volunteers have worked to protect the beach and the region's ecotourism.
Many are fishermen who used to hunt turtles prized for their meat.
