The top layer contains a lattice of guanine nanocrystals, and by exciting this lattice, the spacing between the nanocrystals can be manipulated, which in turn affects which wavelengths of light are reflected and which are absorbed. Germinal layer lies on the basal lamina (a) and below lies the tissue of the dermis. They are legless (some species retain a pelvic girdle) and have an elongated body, this means that paired organs appear one in front of other and they only have one functional lung. their tounges and their bodies.

The rattle consists of up to 20 loosely interlocking hollow shells, each of which is at one point the scale covering the tip of the tail. ISO bodies are concentrically shaped, similar to mammals. In order to warm up or cool down, lizards and other reptilessuch as snakes, turtles, and crocodilesmove to different areas of their environment. Eating foods high in antioxidants. In epidermis, different layers are observed. The scales originate from the epidermal superficial layer of the skin and form keratinized wrinkles and may have bony plates underlying them (osteoderms).

These protrusions are essentially only of epidermal origin, without dermal participation [1]. A series of smaller plates, which on the border with carapace and plastron, are called inframarginal scutes. Additionally, epidermal scales may be modified into crests, spines, or horn-like processes. Skin histology of the tail (A, B) and ventral part (B, D) of Burmese Python (Python bivittatus).
