It is the most common marine reptile in the Mediterranean. It is an omnivorous species, with a diet that varies from echinoderms (sea urchins, starfish …) to jellyfish, from molluscs to algae.
The powerful beak allows it to crush the shells of prey. It lives mainly in the open sea.
In the Mediterranean, it nests in the summer on the southern beaches of the basin. Each female can lay up to 120 eggs for each brood and the young at birth do not exceed 5cm in length for 20g in weight.
They are often seen resting on the surface.
