Two species of sea turtles nesting on the beaches of Mediterranean. Caretta caretta ( Loggerhead sea turtle) and Chelonia mydas (Green sea turtle). They mate in April and nest 3-5 times every 2-3 years. The nesting interval is about 15 days.
C. caretta is carnivorous and swims at about 200m depth of sea. C. mydas is herbivorous and swims at 20-50 m depth of the sea.
The temperature of the developing eggs is what decides whether the offspring will be male or female. High temperature (32 oC) makes them female and low temperature (26 oC) makes them male.
The nests are about 50-60 cm depth for loggerhead and 90-100 cm for green turtles. The clutch size about 50-150 eggs at the size of about a ping pong ball. The incubation period is about 45-65 days.
The hatchling turtles disorientate when they see a light source other than sea. Please use low energy lamps and screen your visible lights from sea.
