Olive Ridley Sea Turtle (Lepidochelys olivacea) is one of the 7 species of marine turtles that visit Mexican beaches to lay their eggs. Egg laying occurs almost exclusively at night. After female has chosen a place for the nest, she begins digging. First a shallow and wide "bed"is made under and around the female's body followed by excavation of a deeper and narrow chimney - like hole where in between 80 and 120 eggs will be deposited.
