Considered as the first animals on land with the ability to live and multiply on land (amniotic egg). Amniotic egg- . a shelled, water-like sac that enables reptiles to complete their life cycles on dry land.. Maya, Courtney, and Jae-. L. ynn. Characteristics. Reptiles are cold-blooded, vertebrates with scales covering their skin. . They are considered as tetrapod's (with four legs or leg-like appendages) even though legs are absent in some animals, like snakes. . Science class. How are animals classified?. Animals are classified based on their similarities and differences…. Scientists divided the animal kingdom into two main groups, vertebrates and invertebrates.. 2. Amniotic eggs have . membranes that protect the embryo from . desiccation, cushion the embryo, help with gas exchange, and store waste material.. 3. The amniotic eggs of reptiles and birds also have leathery or hard shells that protect the developing embryo, and a yolk that supplies food to them.. Chapter 27 and 28.

The amniotic sac contains everything an embryo needs to grow.. some develop inside mother’s body. some develop inside a tough, . semipermeable. . shell. The amniotic egg allowed vertebrates to reproduce on land. These were the first class of organisms to adapt to life on land. They are believed to have evolved from the amphibians millions of years ago. There are about 10000 different species of reptiles on earth. They are cold-blooded animals belonging to the phylum Chordata of Animal kingdom.
