Mammals are warm-blooded animals. This will help mammals live at various temperatures. Some mammals live at freezing temperatures, but other mammals live at very high temperatures.
Reptiles leave their children when they give birth
While mammals maintain the same color, reptiles can change the color based on their mood and environment
Most reptiles lay eggs, but with some snakes and lizards, eggs can develop in their mothers and give birth to young children. Crocodiles and tortoise shells are like eggs of birds. Sea turtles, snakes, and most lizards lay eggs, and the cortex is soft. A turtle laying eggs on the beach
In contrast to spawning, young people who give birth seem to be mostly in the category of mammals. There are only two exceptions, Acupuncture and Platypus, and all mammals give birth. On the other hand, reptiles can only lay eggs to hatch their children. Like the two unusual mammals laying eggs, this trend is broken by some species that provide birth dates for their infants.
The main difference between mammals and reptiles is how to regulate body temperature. Reptiles need an external heat source like the sun, but mammals can generate body temperature. That's why most reptiles are warming up under the sun. As reptiles lay eggs, mammals give birth to young people. Mammalian cubs depend heavily on the protection and nutrition of their parents, and reptiles can self-destroy at the time of hatching, so they do not need the parent's life to hatch. In addition, mammals have hair and furs, and reptiles have scales.
However, there are some differences. Mammals have hair throughout the body, but reptiles have scales. While reptiles lay eggs, mammals have births that produce milk for young people. Reptiles have only 3 hollow hearts and 4 mammals. Reptiles continue to grow throughout their lifetime and replace lost teeth. On the other hand, mammals stop growing in adulthood and make only two sets of teeth. Finally, the biggest difference is that mammals are endothermic and internally regulate body temperature, reptiles are sensitive to temperature because they depend on the environment to do this.
Fertilization is in the body of most reptiles and mammals. Most reptiles lay eggs; most mammals give young turnips. But there are exceptions. Several snakes, including the Python snake, lay live offspring. Mammals of two primitive species - ducks treated with acupuncture and ducks are known as monofia - make leathery eggs similar to reptiles. The mammalian heart consists of four ventricles, two ventricles, and two atria. One channel sends the oxygenated blood to the organ and the other channel re-oxygenates the blood towards the lungs. As a result, the mammal stains warm. In other words, regardless of the environment, generate heat, keep body temperature constant.
