Reptile eggs are soft-shelled so that the babies can break out of the shells. Bird eggs are hard-shelled, because baby birds use their beaks to crack the shells of their eggs, but since reptiles don't have beaks to use to break their shells, their eggs have to be soft-shelled.
The amniotic egg is the feature present in reptiles and absent in amphibians that freed reptiles from dependence on water for reproduction. The amniotic egg has protective membranes and allows reptile embryos to develop on land, reducing the need for water for reproduction.
The Amniotic egg. Remember, reptiles are believed to have evolved from amphibians. Where do amphibians lay there eggs? - The water. Why? because their eggs are soft. The reptiles are the first to lay the amniotic egg which has a hard shell. If an amphibian tried to lay its egg on land, gravity would squad it because an amphibian's egg is jelly like. With the hard shell of the amniotic egg, reptiles have greater change of reproduction.
The amniotic egg allows reptiles to reproduce on land, away from water.
No, not all reptiles have lungs. Some reptiles, like snakes, have evolved specialized structures like air sacs that help in breathing. Crocodilians are an example of reptiles that use both lungs and special air sacs.
Reptiles, mammals, and birds lay amniotic eggs, which contain a yolk to nourish the developing organism. Eggs are used to protect the organism as it develops, and the egg also aids in gas and energy exchange.
The answer is, the colour and the pattern of the egg and the shape.
birds - warm blooded have wings and have hollow bones reptiles - cold blooded or endothermic and reptiles have soild, dense bones birds- has a normal hard shelled egg reptiles- has a special type of egg
A special type of reptiles called "Archosaurs."
Reptiles (I think)
Some reptiles lay egg in the nest and some reptiles lay egg on the land.

There is no such thing as a "cleidoian egg." It may have been misspelled or misheard. If you meant to ask about a "cleidoic egg," it is a type of egg found in reptiles and birds that has a shell and several extra membranes to protect and nourish the developing embryo.
Reptiles are thought to have developed after the evolution of an amniotic egg, which allowed them to reproduce successfully on land without the risk of the egg drying out. This adaptation was a key factor in their ability to transition from an aquatic environment to a terrestrial one.
