EVERYDAY SCIENCE

Detailed explanation-1: -The shells of reptile eggs are leathery and require a moist environment.

Detailed explanation-2: -Most reptiles lay eggs with soft, leathery shells, but minerals in the shells can make them harder. Crocodilians and some kinds of turtles lay eggs with tough shells-more like a bird’s egg. Female reptiles often build nests to protect their eggs until they are ready to hatch.

Detailed explanation-3: -Reptiles have an amniotic egg, which means that it has a protective layer that separates the developing embryo from the environment. Amphibians, by contrast, lack an amniotic egg.

Detailed explanation-4: -Most lizard and snake species lay leathery eggs as well, although some snakes give live birth or carry the eggs inside their bodies until the eggs hatch. The leathery exterior helps hold in moisture and protect the babies while remaining slightly flexible.
