Compare skeletons of mammals and reptiles. Write down their differences and similarities.

The main similarities will be the same structure of the spine (5 sections), hind and forelimbs, the presence of a skull and chest. However, the different way of life that these animals lead, affects the differences in their skeletons. So, the limbs in mammals are located directly under the body. Reptiles, on the other hand, move differently, so their legs are placed on the sides of the body. Also, reptiles always have 5 fingers, while some mammals have only 4.
