Osteoderms are dermal bone structures that support the upper layer of skin and serve as protection against the elements in a large variety of extinct and extant organisms, especially reptiles. [1] This structure is commonly called "dermal armor" and serves to protect the organism, while also helping with temperature regulation.
Similar to the Western tambourine, it consists of a circular frame made of the wood of the jackfruit tree, between 7 and 9 inches in width and 2 to 4 inches in depth. It is covered on one side with a drumhead made of monitor lizard skin (specifically the Bengal monitor, [4] Varanus bengalensis, now an endangered species in India), while the other side is left open.
Just prior to shedding, the skin becomes dull and dry looking and the snake's eyes turn cloudy or blue-coloured. The old layer of skin splits near the mouth and the snake wriggles out, aided by rubbing against rough surfaces. In many cases the cast skin peels backward over the body from head to tail, in one piece like an old sock.

In zoology, a scale (Ancient Greek: λεπίς, romanized: lepís; Latin: squāma) is a small rigid plate that grows out of an animal's skin to provide protection. In lepidopterans ( butterflies and moths ), scales are plates on the surface of the insect wing , and provide coloration.
The body temperature of the lizard during hibernation is 15.0 to 30.5 °C, but in many areas, the average body temperature during hibernation is around 16-18 °C. [ 8 ] The species is one of the few monitor lizards that tolerate relatively cold temperatures, being present as far north as south-west Kazakhstan.
