A Turtle dig a two feet nest with her hind flippers and lay almost 100 to 150 eggs.In about two months the hatchlings would break through the shells and would make a dash for the sea by natural instinct which they tend to locate by reflection of the moon and the starlight on the water surface.

The hatchlings drift with the oceanic current and sometimes they happen to have covered the entire ocean.These hatchlings when become reproductively active(10 to 15 years,for some species 50 yesrs) use the earth's magnetic field to find the beach where they were born so that they can start the cycle again.
