What does squama mean?
A squama is a single scale, especially one of the overlapping scales that cover the body of a snake or lizard. In zoological writing, the term distinguishes reptilian scales from other kinds of scales, such as those of fish or the protective plates of a tortoise. The singular is relatively uncommon, but the plural squamae appears in scientific descriptions of reptile anatomy, skin structure, and identification. Squama comes from Latin, where squāma means “scale” or “scale-like plate.” Its broader relatives include the adjective squamous, meaning “scaly” or “covered with scales,” and squamate, a term associated with reptiles such as snakes and lizards. For general writing, scale is usually the clearer choice; squama is most useful when precise zoological terminology is required.
