Reptiles, with amphibians, invertebrates, fish, birds and mammals are among the six main animal groups. Reptiles They are tetrapods which were about 340 million years ago different from ancestral amphibians. In the process of evolution from amphibians, there are two characteristics formed by early reptiles: scales and amniotic eggs (eggs with an internal fluid membrane), of great significance for them.

As described in the previous chapter, the skin of reptiles represents its greater commitment towards a terrestrial life.
There is considerable keratinisation, with skin glands lower than amphibians.
There are scales but the scales of the dermal scales of the fish are radically different.
The reptile scale usually does not have the kid or any major structural contributions from the dermis.
Rather, it is a fold in the epidermis of the surface, thus an epidermis.
The flexible hinge is the connection between adjacent skin scales.
If the epidermal scale is large and flat, it can be called a scute. Epidermal scales can also be modified into processes like crests, spines or horns.
Although not usually connected to scales, in many reptiles dermal bone is present.
Examples of this are gastralia, which is a collection of bones in the abdomen.
If the dermal bones support the epidermis, the plates of the dermal bone underneath the epidermal scales are called osteoderms.
Crocodiles, some lizards, and some extinct reptiles are found in osteoderms. Probably modified osteoderms are some bones of the turtle shell.
