Also, mammals have oil and sweat glands. Some examples of mammals include humans, dolphins, giraffes, horses, spotted hyenas, etc. Reptile is a cold blooded vertebrate that cannot maintain constant body temperature. Therefore, the reptile body temperature fluctuates according to the environmental temperature.
Furthermore, reptiles have skin covered with hard and dry scales. Unlike mammals, reptiles lay eggs, and they abandon their young after hatching the eggs. Moreover, most of the reptiles are terrestrial animals, but few are aquatic. The general belief is that, during the evolutionary timeline, reptiles have evolved from the amphibians. Some examples of the reptile species include alligators, snakes, lizards, turtles, etc. The key difference between mammal and reptile is the way they regulate body heat.
Mammals can produce body heat while reptiles need an external heat source such as the sun to maintain body temperature. It is, for this reason, most reptiles bask in the sun to get warm.
Another difference between mammal and reptile is that the mammals give birth to live young while the reptiles lay eggs.
Also, the mammal offspring is very dependent on their parents for protection and nourishment while the reptile offspring do not become dependent on their parents since they abandon them after hatching the eggs.
Mammals are warm-blooded animals and have mammary glands from which milk is secreted to feed their offspring. They have bodies covered by hair. Hairs in the body help mammals to survive cold climates.
Reptiles are another type of animal class of the vertebrate group. Reptiles are cold-blooded animals and depend on their surroundings to warm up their body. Reptiles have dry skin which is covered either with horny plates or scales. They breathe by using their lungs. Most of the reptiles lay the egg on the ground and eat other animals for survival. Mammals are one of the five classes of vertebrate animals.
Mammals give birth to live young and feed their young with the milk secreted from their mammary glands. Besides these characteristics, mammals are distinguished from other classes by some other characteristics. They have hair covered all over their body. They also have sweat glands on their skins. Mammals have a lower jaw bone firmly attached to the skull. The lower jaw bone is one continuous bone. Mammals and reptiles are just two of these classes, in addition to birds, amphibians, and fish.
The epidermis, or skin, is an apparent difference between these two classes of animals, and one you will be easy to identify on a glance. Some mammals have very different hair and present themselves in the form of long whiskers, defensive quills, and horns.
The hair on these animals is primarily used to insulate the body, keeping it warm when the environment is cold. Fish scales are made of enamel and dentine, like your teeth, but reptile scales are made of protein. The cardiovascular systems in reptiles and mammals is another significant difference between these animals. This means they rely on the temperature around them to regulate their body temperature and perform regular bodily functions, like digestion.
Because they are cold-blooded and need warm exterior temperatures, you will only find them in the wild in warmer locales.
