Bony Fish
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.
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
no they have dry skin.
Denticles are small tooth-like structures found on the skin of cartilaginous fish like sharks and rays. They differ from the bony fish's scales, which are hard, flat plates covering their bodies. Denticles help reduce drag in water and provide protection, while scales are more rigid and serve as a form of armor for bony fish.

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.
Yes, scalloped hammerhead sharks do have scales. Like all sharks, they are covered with dermal denticles, which are small, tooth-like structures that provide a rough texture and help reduce drag while swimming. These scales are different from the scales found on bony fish, as they are more similar to teeth in structure.

Sharks do not have scales. Their skin is somewhat like sandpaper, rough-surfaced. The ancients used to use sharkskin for sandpaper.
Dermal denticles. Literally, "skin teeth." They are similar in structure to the teeth of a shark. See http://en.wikipedia.org/wiki/Dermal_denticle
They have special scales like many sharks called placoid scales
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.
Sharks, as an example, do not have scales. Re: Sharks instead have something like skin, but have these things on them that make them very rough. They could even scrape off your skin!! For a weird fact, people used to use the skin of sharks as sandpaper.
