The Caretta Caretta is a large sea turtle with a reddish-brown shell consisting of keratin plaques. It weighs on average 90kg and can reach a length of one meter. It feeds mainly on seaweed and invertebrates, but has a preference for jellyfish. It lives in the sea but its survival fully depends on the land, since its biological cycle ends on land, with its egg-laying and hatching, and the hatchlings subsequently entering the sea. The hatchlings face many natural enemies –crabs, seagulls and fish- and their death-rate is exceptionally high. It has been calculated that only one out of every thousand baby turtles lives to become an adult turtle!
The most important egg-laying beach throughout the Mediterranean is situated in the area of Sekania on Zakynthos. The nests in Sekania range from 500 to 1,000 -depending on the year- one of the highest egg-laying densities in the world. Other important egg-laying beaches in the country for this species are found in Lagana Bay (on Zakynthos), Kyparissiako Cove, Lakoniko Cove, in Rethymno and Chania.
