the shell keeps the egg from drying out by that I mean it keeps it moist or by leaving it it a wet dry area
Reptiles have hard-shelled eggs because the shell provides protection and support for the developing embryo. It allows for gas exchange with the environment and prevents the egg from drying out. This adaptation is key for reptiles, as they lay their eggs outside of their bodies.
Reptiles have developed an outer covering of scales or bony plates to retain their body moisture. Amphibian skin lets water pass in and out so amphibians must stay in or near a water source to keep their bodies from drying out. Amphibians develop from egg to larvae to adult in water. Reptiles do not have a larval stage.
They don't need thick bark to keep them from drying out because the rainforest is so wet
Some reptiles give live birth. Others (in particular, certain snake species) actually keep the eggs inside their body until they are just about ready to hatch.
So they can have baby King Cobras. Cobras are reptiles and most reptiles lay eggs, those that don't normally live in colder climates where eggs laid on or under the ground would not get warm enough to incubate. In this case the eggs are kept inside the reptiles body to keep warm and the babies are born straight from the mother.
Most reptiles simply abandon their eggs to 'fate' once they're laid. Some species of lizards and snakes will stay close-by and actively discourage anything from disturbing the 'nest'. The majority of animals know instinctively to avoid contact with reptiles.
Frogs' eggs, or frogspawn, need water or they will dry out and die. The eggs of a frog do not have a solid, protective covering like birds' eggs or reptiles' eggs do, so laying them in water preserves the developing tadpole from dehydration.
Land dwelling animal's eggs have shells (hard or soft) to keep them from drying out. Fish eggs don't need shells because being in water they won't dry out.
Reptiles lay soft eggs. These eggs unlike a birds are not meant to be rotated or disturbed, as it could lead to killing the baby. These eggs are packed down into dirt which will keep them warm and safe.
they have vascular tissue to keep form them drying out.
