Reptilia- Chelonia mydas
The organisms found in Class Reptilia are the first fully terrestrial vertebrates. They first appeared in late Paleozoic period. The eggs of the organisms in Class Reptilia develop in a cleidoic, or closed/self-contained, egg. The embryo of the egg has an extra-embryonic membrane and a relatively impermeable shell. The organisms possess lungs for respiration as well as a heart with two atria and ventricle partially or totally divided. The Reptilia has one occipital condyle. The skin of the organisms have epidermal scales or bony plates. The Reptilia are ectothermic, but are sometimes called heliotherms because they can regulate body temperature by using solar radiation.
Examples of organisms found in the Class Reptilia include what we know today as reptiles.
