At Drake Bay, Costa Rica
|Jason with Rob James, Director of Fundacion Corcovado|
At Fundacion Corcovado we put in turtle nest traps. The way they work, when a turtle hatches it will hit the trap and stay. It doesn’t hurt the turtle, but it keeps them in one place, so that they don’t escape and they can count how many turtles hatched. After they count how many turtles have hatched, they pick them up and put them into a bucket to put them on the sand on the beach so they can go toward the ocean. Why they put them on the sand is so they have a better chance of reaching the ocean, and they don’t get killed by crabs and birds that might want to eat them.
Why they put them on the beach instead of the ocean is they want them to remember the beach so that they lay their eggs there when they get to be adults.

Most of the turtles that nest there are Olive Ridley sea turtles. But they did find one green sea turtle nest and one dead baby. It was probably killed by a crab.

Here is more information about sea turtles from research that I did.
Why turtles nest on land and not in the ocean (this was a question I had about sea turtles):
- Babies have to breathe air
1. Body pit, digging with flippers as the female sea turtle turns her body around
2. Egg cavity: The sea turtle digs with its back flippers to make a hole that looks like a tear drop that the eggs go in.
3. Lays eggs: 80-120 eggs in one nest (the eggs are flexible - it allows the females to hold more eggs and the eggs don't break when they hit the bottom of the egg cavity)
4. She covers the egg cavity with sand.
5. Throws sand in all directions to disguise the nest so that predators don't find the eggs.
6. She goes back into the ocean to return to the feeding place.
