What happens in the interlude is unknown. The population of green Turtles in the Mediterranean is thought to be isolated from other populations. There is evidence to show that turtles enter and exit the Mediterranean, but it is thought that this is due to navigational error. The Mediterranean population of Green Turtles is very small compared to those world-wide. Generally, the green turtle nests within the tropical latitudes, on gently shelving sandy beaches protected from the sea.
Times vary slightly depending on exact location of nesting beach.
The female comes ashore at night on a gently sloping sandy beach. The site of the nest is always well above the high tide mark. A flask like pit is dug and the clutch of eggs deposited in it. The nest is then camouflaged with a covering of sand. The turtle then returns to the sea.
