After Some species have been reported to lay 250 eggs, such as the hawksbill. After the hole is dug, the female then starts filling the nest with a clutch of soft-shelled eggs one by one until she has deposited around 50 to 200 eggs, depending on the species. Using her hind flippers, she digs a circular hole 40 to 50 centimetres (16 to 20 in) deep. The mature nesting female hauls herself onto the beach, nearly always at night, and finds suitable sand on which to create a nest.
