Question

what is use of scales ?????

Answer 1

$\huge\star\green{{Answer...!! }}$

The scales that cover their bodies are dry to the touch and quite impressive. Like human fingernails and rhinoceros horns, these scales are made of a strong protein called keratin. Contrary to popular belief, scales are not reptiles' skin; their skin actually lies beneath this keratin layer, which serves many functions that help reptiles survive in the wild.

In most biological nomenclature, a scale is a small rigid plate that grows out of an animal's skin to provide protection. In lepidopteran (butterfly and moth) species, scales are plates on the surface of the insect wing, and provide coloration.
