Sharks do not have scales. Their skin is somewhat like sandpaper, rough-surfaced. The ancients used to use sharkskin for sandpaper.

Sharks do not have scales like bony fish. Instead, they have rough, tooth-like scales called dermal denticles that provide protection and reduce drag in the water. These denticles also give sharks their rough texture.

Nearly all fish, including sharks, have scales. We don't have any fossilized impressions of Megalodon skin, but there is no reason to believe that they didn't have scales like other sharks. The scales on shark skin are useful because they trap water against the shark. Thus, the water that rubs against them mainly rubs against the water in between the scales, and that greatly reduces drag.
Shark skin looks and feels like it is covered with tiny teeth. In fact, their small, rough placoid scales (also called denticles), have the same structure as sharks' teeth! Shark skin is sometimes used as sandpaper.www.vanaqua.org/education/aquafacts/sharks.html
Sharks do not have scales, but they do have small bones embedded in their skin, which are called dermal denticles.
Placoid scales, also known as dermal denticles, are the tooth-like scales embedded in the skin of rays and sharks. They provide protection and reduce drag when swimming.
Sharks are fish so, like all fish, they have scales. In the case of sharks, these scales are somewhat different in composition, and actually make up a yep of skin. Shark skin is made up of tiny, hard, tooth-like structures known as dermal denticles or placoid scales.
They have special scales like many sharks called placoid scales
