La tortuga boba cava su nido en la arena, de noche, y deja en él unos cien huevos. Dos meses después, las crías salen todas juntas, también de noche, y corren hacia la parte más clara del horizonte, que suele ser el mar. Por eso las farolas de un paseo marítimo pueden despistarlas. En varias playas del Mediterráneo español, grupos de voluntarios vigilan los nidos hasta que nacen las crías.
