Reproduction: Most lizards deposit their eggs in a simple nest. The female skink may coil around her eggs to protect them from intruders. Other lizards do not lay their eggs, but give birth after hatching their eggs inside the body. Still other lizard species reproduce similar to mammals, giving birth to live young. Unlike female mammals, these female lizards do not nurse or care for their young after birth. Some species of North American whiptails and European lacertid lizards have only female individuals; adult females lay unfertilized eggs that hatch only into females.
