Mammals

Mammals are vertebrates that give birth to a live young. Most offspring are not yet able to look for food and need nourishment in the form of milk from its mother’s mammary glands. Mammals have furs or hair and have sweat glands. Furthermore, mammals have a part in the brain called neocortex that regulates body heat. They also have a middle ear and a jaw made from a single bone.

Reptiles

Reptiles are vertebrates and are mostly egg-laying creatures, although there are reptiles that give birth to live young such as viper snakes. Examples of animals that are reptiles are alligators, crocodiles, snakes, lizards and turtles. The eggs of reptiles have a hard outer shell that protects the embryo from outside harm. Most reptiles are carnivorous but their digestion and metabolism is very slow.
