What features of reptile reproduction contributes to the preservation of offspring?

The egg itself in reptiles is covered with a dense shell – this already contributes to greater survival than in amphibians. Lizards are carefully looking for a place to lay their eggs. It is always some kind of mink, cracks in stones, hollow trees. So they try to protect eggs from predators. Turtles swim a long distance in order to reproduce. They crawl with difficulty on land, but try to find a secluded hole for their offspring. However, this is where the care of lizards and turtles for their children ends. But crocodiles guard their eggs for a long time and carefully, protecting it. After hatching, the little crocodiles will be carefully transported to a more comfortable place in the water.
