What are the features of the skin structure in mammals?

The skin of mammals is very different from the same fish, reptiles and others. The main difference is the close location of the capillaries to the surface, which makes the skin different in color. In most mammals, it is pinkish. So does the firmness and elasticity. It does not provide protection, but it helps to move freely. Hair is characteristic. Hair follicles are found in most mammals. Also, this skin does not have the ability to quickly renew itself. We do not shed skin layers. It flakes off in very small pieces that are invisible to us.
