Turtles of Zakynthos

The sea turtles of Zakynthos, called coaches, are the largest of the eight species of turtles swimming in the world's oceans. The average large turtle of this species weighs 100 kg and reaches 120 cm in length. Greece is the only European country where these marine animals lay eggs. The Laganas Bay on the island of Zakynthos has the most of this endangered species. Male turtles live about 60 years. In the nights from June to August, female turtles come ashore and lay about 200 eggs, bury them to a depth of 40-60 cm and cover them with warm sand. About 8 weeks after burial, the cubs hatch and go to the sea. Then the surviving adult females return after 30 years on the same shore to lay their eggs in turn. 
Therefore, in 1999 in the southern part of the island of Zakynthos, a National Marine Park has been created, protecting about 6 km of secluded sandy beaches, so that turtles can safely create a generation.
